I have two disks: nvme0n1 and nvme1n1. I was planning on using Logical Volume Manager? 2 and someone else told be BTRFS was better, so I looked into it, and sure enough, it looked better for my use-case. I created the btrfs file systems for each partition pair (/nvme0n1p3 and /nvme1n1p3) and 4. Now, I am trying to get to the next step of installation, in which I mount my partitions / volumes and then install the necessary linux packages.

Hi, what setup are you trying to achieve? Do you want to put everything (/, /home) in one partition as subvolumes then use the 2nd partition just for storage or split them etc / in one partition and /home in the other partition? Are you also planning to use btrfs snapshots? Have a look in https://wiki.archlinux.org/title/Btrfs .
Within a btrfs partition, you can create subvolumes to put traditional Linux partitions (etc /, /home) https://wiki.archlinux.org/title/Btrfs#Subvolumes .
Usual setup on a single btrfs partition is to create subvolumes for / and /home so that you can snapshot / without including /home data. You usually mount the btrfs partition to /mnt then create subvolumes in /mnt etc btrfs su cr /mnt/@home && mkdir -p /mnt/home. You then umount /mnt and mount root subvol then other subvol with the folder path etc mount -o compress=zstd,subvol=@home /dev/nvme0n1p2 /mnt/home/. After mounting all subvolumes you would mount esp (mount --mkdir /dev/efi_system_partition /mnt/efi) then continue with your arch install.
By bindings do you mean mount options? See https://man.archlinux.org/man/btrfs.5#MOUNT_OPTIONS
ESP setup is independent of btrfs and is the same process for all filesystems (just need to mount esp and install bootloader to it in chroot).
Also in order to boot into a btrfs root subvolume, you need to use this kernel parameter rootflags=subvol=/path/to/subvolume (this step is commonly missed) https://wiki.archlinux.org/title/Btrfs#Mounting_subvolume_as_root

Hi, what setup are you trying to achieve? Do you want to put everything (`/`, `...
trying to evenly storage split them. i have /boot for my first partition, /swap for my second partition, / for my third partition, and /home for my fourth partition. When I refer to bindings I mean taking two partitions and treating them as one using BTRFS
I don't really care about subvolumes or snapping unless they help me achieve making two partitions into one
also please ping me when you have a response so I know to check here
fringe vale
@hexed isle sorry I'm not familair with mutli-disk setups but I believe it should be pretty much the same process where you just treat the 2 disks as partitions (can mount / to a partition disk 1, /home to a partition disk 2). Grub/systemd-boot/uki can all boot into /boot in btrfs so you don't really need a separate /boot partition. Also on btrfs a swapfile is generally recommend to be used over a swap partition. If you're not planning to use subvolumes I think you just need mount the path without subvol etc mount -o compress=zstd /dev/nvme0n1p1 /mnt/home/. If you want to evenly split data across 2 disks (treat 2 disks as a single btrfs partition), have a look into raid 0 ( I'm not familiar with it) https://wiki.archlinux.org/title/Btrfs#Multi-device_file_system

why not a swap partition?
how am i supposed to limit the RAM a swap file takes up?
fringe vale
you can use swap partition, swapfile is just more flexiable (can resize easier)
fringe vale
how am i supposed to limit the RAM a swap file takes up?
it will be as large as the swapfile size you set it to be
are you planning to use swap for hibernation? If you don't need hibernation you could try using zram instead if your ram is not too little
hexed isle
are you planning to use swap for hibernation? If you don't need hibernation you ...
yeah i would like to hibernate idk how to set that up though
solid granite
to hibernate i think you have to use a swap partition
you set the kernel parameter resume=UUID=<UUID of swap partition>
Not sure what you mean by "bindings". If you mean what gets mounted where, that's managed in /etc/fstab.
You mount BTRFS partitions like any other filesystem. mount /dev/<partition> <mountpoint>; if you want to mount a specific subvolume on that partition, then you pass it as a mount option. You can use the subvolume ID, path, or both. example: mount /dev/<partition> <mountpoint> -o subvol=my-subvol (if the subvolume is called my-subvol)
The ESP has to be FAT32. There's no way around that.
@hexed isle
hexed isle
Not sure what you mean by "bindings". If you mean what gets mounted where, that'...
sorry that was stupid language to be using when i say bindings i mean how would i mount two partitions connected by btrfs under root?
solid granite
ah, so a multi-device filesystem?
hexed isle
yes
thats what i am trying to achieve
i have 2 disks with 1 root, 1 home, and 1 swap partition each, and i want each root and home to be treated as one respectively
hexed isle
ah, so a multi-device filesystem?
does that make sense
solid granite
Yeah, give me a moment, I'm lagging balls running out of ram building chromium on Gentoo 😂
I know how to do this
i'm assuming they are currently separate file systems
and you want to join them together
solid granite
alr
hexed isle
and you want to join them together
i used the mf.btrfs command and specified both devices
for the root and home points
solid granite
oh
okay so you should have a mult-device file system
if you do lsblk -f
you should see that both of those partitions have the same UUID
hexed isle
they do
solid granite
okay
solid granite
yeah
hexed isle
alright
solid granite
do you have that file system mounted anywhere
hexed isle
no
solid granite
can you mount it somewhere
so we can see what type of RAID it's doing
sudo btrfs device usage <mountpoint>
it should show info for both disks
for example, i have 2 500 GB hard drives in RAID0 (striping, no redundancy)
$ sudo btrfs device usage /media/hdd_root
/dev/sdb1, ID: 1
Device size: 465.76GiB
Device slack: 0.00B
Data,RAID0/2: 444.75GiB
Metadata,RAID10/2: 21.00GiB
System,RAID10/2: 8.00MiB
Unallocated: 1.00MiB
/dev/sdc1, ID: 2
Device size: 465.76GiB
Device slack: 0.00B
Data,RAID0/2: 444.75GiB
Metadata,RAID10/2: 21.00GiB
System,RAID10/2: 8.00MiB
Unallocated: 1.00MiB
the metadata and system info part of the filesystem is striped and mirrored but the data is only striped
if it's not already in the RAID mode that you want, you can change it
hexed isle
so we can see what type of RAID it's doing
i have to mount both partitions?
solid granite
no, mounting any of them mounts the whole file system
it will automatically figure it out
lsblk will only show one partition as being mounted to that mount point, but that is normal
$ lsblk -f
NAME FSTYPE FSVER LABEL UUID FSAVAIL FSUSE% MOUNTPOINTS
...
sdb
└─sdb1 btrfs df02f1c1-fe1d-4e2a-939d-4a8bfb4c9ed0 42.8G 94% /media/storage
/media/hdd_root
sdc
└─sdc1 btrfs df02f1c1-fe1d-4e2a-939d-4a8bfb4c9ed0
sdd
...
ok good i mounted it and it showed both partitions
solid granite
okay
are you putting them together because you want redundancy, because you want speed, or because you just want one big block of storage instead of 2?
hexed isle
are you putting them together because you want redundancy, because you want spee...
third
i just want them to function as one
2x the storage
solid granite
okay
hexed isle
1 TB is not enough
solid granite
for example, i have 2 500 GB hard drives in RAID0 (striping, no redundancy)
```
...
can you show this
hexed isle
for example, i have 2 500 GB hard drives in RAID0 (striping, no redundancy)
```
...
it shows the same except the first one (ID 1) has the Data thing but it says Data,single and the second one just doesnt have the data thing at all
/dev/nvme0n1p3, ID: 1
Data,single: 8.00MiB
/dev/nvme1n1p3, ID: 2
(doesnt have the data thing at all)
everything else matches up with yours aside from the storage space differing from 440 something GiB to 600 GiB
man im so mad rn that was so counterintuitive i didnt know I had already done it for the most part
i thought there was a separate device kinda like when you use mdadm
solid granite
sudo btrfs balance start -dconvert=raid0 -mconvert=raid10 <mountpoint>
this will change your disks to RAID0 (striping, no redunancy, combined capacity, extra speed)
depending on how much data you have stored, it might take a while because this will reallocate everything
hexed isle
```
sudo btrfs balance start -dconvert=raid0 -mconvert=raid10 <mountpoint>
```
t...
i have no data whatsoever lol (im installing using bootable media usb)
solid granite
it should be fast then
hexed isle
i dont wanna boot into arch until im 100% sure i got the core components done since i dont wanna fuck up
i learned my lesson after using archinstall that you should do things your way
solid granite
you can see if it's done with btrfs balance status <mountpoint>
hexed isle
are all mountpoints predefined?
what are all the mountpoints i know /mnt and /home are some
solid granite
wherever you mounted it
hexed isle
no i know but if i type in /mount /dev/nvme0n1p3 /regdufhiotgdfj it errors
solid granite
partitions are either manually mounted by you, or automatically mounted at boot at spots defined in /etc/fstab
solid granite
no i know but if i type in /mount /dev/nvme0n1p3 /regdufhiotgdfj it errors
that's because regduf... doesn't exist
hexed isle
ok
solid granite
if you make that directory then it would work
hexed isle
partitions are either manually mounted by you, or automatically mounted at boot ...
so i need to edit fstab before im finished correct?
that way it knows what to mount
solid granite
arch comes with a tool to generate it automatically based on what you have mounted manually during installation (genfstab)
that's part of the installation guide
solid granite
it sees what you have mounted at /mnt
hexed isle
well yeah i know
i have a swap partition cause i prefer it that way i used the mkswap
solid granite
yeah
if you did swapon then genfstab will see that swap partition and add it to the fstab for you as well
hexed isle
```
sudo btrfs balance start -dconvert=raid0 -mconvert=raid10 <mountpoint>
```
t...
holup why raid10
solid granite
it just makes it a bit safer in the event of disk damage
highly unlikely that it would ever save your ass, but it just writes metadata to both drives
you can do raid0 if you want, but it doesn't cost much space and should have no performance impact
solid granite
hexed isle
what is dconvert and what is mconvert
solid granite
converting the data and metadata into the specified raid levels
see man btrfs balance
solid granite
cool
solid granite
that is the amount of data currently stored
i think
well it allocates space in advance
hexed isle
not like i give a shit about the extra 2GiB
solid granite
you will probably want to edit the fstab after generating it to enable things like automatic TRIM/DISCARD and/or compression
i use compress-force=zstd and discard=async
hexed isle
hold on im just removing this random ass artifact left behind by mdadm back when i was fiddling with that it will take me another 30 sec
ok so i dont know how i managed to do this
but nvme0n1p1 and nvme1n1p1 are both synced via raid
not btrfs
solid granite
you should disable that
hexed isle
ok so context i was working on trying to use lvm and was told btrfs was better so i switched to that and the arch wiki was weird and told me to made two separate esp parts and then make a volume out of them
solid granite
because that's likely to corrupt what btrfs is doing
solid granite
i'm surprised it hasn't broken it already lol
hexed isle
i dont need both
solid granite
i have no idea how mdadm works
hexed isle
i'm surprised it hasn't broken it already lol
it was a silent error cause i wasnt running lsblk with -f
solid granite
you only need 1 esp
hexed isle
i have no idea how mdadm works
im not gonna fuck around and find out anyway
the fact that this btrfs even works is awesome
alright im rebooting
hexed isle
uh idk it said something weird
solid granite
oh you're just restarting the iso
hexed isle
are you done with the installation?
almost im past the btrfs it seems
im not in it yet
solid granite
have you made subvolumes for root and home
solid granite
it's not required
however
if you ever want to mess with snapshots
you will want to have subvolumes
hexed isle
im still confused about the whole snapshot things
i have a basic idea of what they are
but i dont quite understand them
solid granite
so when you make a snapshot of a subvolume
you are just marking a point in time, and the data that existed then won't get deleted
there is a concept called Copy-on-Write
you make copies of things, but the actual data only exists in one place on your drives
you just have two pointers to it
hexed isle
yeah i've heard about that
solid granite
if you take a snapshot
and then delete files from what you took the snapshot of
or modify them
that data doesn't get deleted
it just gets marked as deleted in the subvolume
but still accessible through the snapshot
only once no subvolumes or snapshots reference a piece of data, does the data actually get deleted
hexed isle
when i make these subvolumes do these become new devices?
solid granite
no
subvolumes are kinda like folders
except it's possible to mount them like they're devices
with the subvol= mount option
but if you just mount the device by itself without a subvol parameter
you can see all the subvolumes on it as directories
and access them like directories
and subvols can be nested in other subvols just like directories
hexed isle
with the `subvol=` mount option
ok but to make a root and home subvolume and then use that normally i'd do this?
solid granite
yeah, so for example if you had subvolumes @ and @home for root and home, you would mount it like
mount /dev/nvme0n1p1 /mnt -o subvol=@
mount /dev/nvme0n1p1 /mnt/home -o subvol=@home
but if you just did mount /dev/nvme0n1p1 /mnt and looked inside /mnt, you would see @ and @home as directories
the @ is just a common naming scheme for subvolumes, they can be named anything though
hexed isle
alright how do i create a subvolu,e
solid granite
mount /dev/nvme0n1p1 /mnt # mount the root subvolume (meaning without a subvol= parameter)
cd /mnt
btrfs subvolume create @
btrfs subvolume create @home
but then i would need to unmount it and do this right
solid granite
if it's already mounted then you can skip the mount
solid granite
swap partitions are just swap
your esp should be fat32
it's easy to fix if they're messed up
hexed isle
if it's already mounted then you can skip the mount
idk it says vfat swap but then for the fat32 there is a 1 by both swap partitions
solid granite
$ lsblk -f
NAME FSTYPE FSVER LABEL UUID FSAVAIL FSUSE% MOUNTPOINTS
sda
├─sda1 vfat FAT32 F586-E5F2 255.7M 0% /efi
└─sda2 btrfs 277c70af-ffb7-437b-8e90-37d37dda1052 247G 71% /home
...
nvme0n1 swap 1 d3e204d3-0390-47e1-b563-5914a3a8d285 [SWAP]
sda1 is my esp and nvme0n1 is my swap
solid granite
that is correct
solid granite
idk it says vfat swap but then for the fat32 there is a 1 by both swap partition...
you have 2 swap partitions?
solid granite
could you post the output of lsblk -f
hexed isle
the mdadm raid thing going on with nvme0n1p1
imma seal up all my cracks they gonna keep coming back
solid granite
it needs to just be a regular fat32 partition
hexed isle
yep
i dont know how to destroy that
wipefs?
every restart that shit comes back bro
there is some metadata doing it
solid granite
you could try just mkfs.fat -f -F32 /dev/nvme0n1p1
this should forcibly overwrite whatever's in there
there may be a specific way you are supposed to uninitialize the raid thing
overwriting it might make the kernel mad
not sure
why do you have 2 btrfs partitions on each drive
i just noticed
hexed isle
why do you have 2 btrfs partitions on each drive
because the p3 on each is the root and the p4 on each is the home
lol
solid granite
the way we've done the subvolumes
hexed isle
sigh if i need to make a correction just say
solid granite
root and home are on the 2 partitions you made into a multi-device fs
hexed isle
yeah
do i need to merge into one part?
i can do that with ease they dont have anything valuable on them
they arent even mounted rn
solid granite
yeah
solid granite
yeah
i'm assuming we've been working with p3 of each drive and that's what you're calling root
is that right
hexed isle
yes
solid granite
yeah so i would delete p4 of each drive and expand p3 into that space
hexed isle
ok so gdisk has a partition type called Linux x86-64 root (/) whats the deal with that
hexed isle
do you have a gpt parition table
gpt
solid granite
the type should be "Linux filesystem"
hexed isle
done
alright let me check if everything is in order
deleting the p4 shouldve wiped the file system or?
solid granite
technically no, but that doesn't matter
you could recreate the partition at the exact same spot and you would see btrfs there again
but when you expand p3 into that space it doesn't make a difference
hexed isle
where exactly is all that data stored if not in partitions?
about the file system and such
solid granite
the filesystem is stored in the part of the disk specified in the partition table
partitions are just a way to divide the disk into parts of certain sizes
modifying the partition table to remove a partition just removes the record of that partition exisiting in the space
unless you actually write zeroes to that part of the disk then the filesystem will still be there
the actual partition table is a very small piece of data stored at the beginning (and i think also the end) of the disk
solid granite
what's stuck
hexed isle
the usb
solid granite
what does it say
hexed isle
idfk
i rebooted and then unplugged it
put it back in
and now nothing is being detected as a boot option
and
its in the uefi menu
solid granite
it shouldn't be possible to corrupt it, nothing should write to the usb
turn pc off, replug usb, then turn on again
hexed isle
ok there what the hell happened there
solid granite
did it work?
hexed isle
how do i check if btrfs is working again
so i mount the partition and then i run a command
@solid granite
solid granite
yeah mount it and check btrfs filesystem df /mnt
you should see total=xxx where xxx is the size of the partitions combined
if it's smaller than it should be, then the fs needs to be grown
hexed isle
for example, i have 2 500 GB hard drives in RAID0 (striping, no redundancy)
```
...
how do i get this
solid granite
the first line is the command that i ran
you would just leave out sudo and do /mnt instead of /media/hdd_root
oh yeah that shows device size as well
solid granite
how do i get this
in this command, are your 2 devices ID 1 and 2? or is it something else like 0 and 1
hexed isle
no its ID:1 and ID:2
solid granite
ok
solid granite
just checking
hexed isle
ok
solid granite
btrfs filesystem resize 1:max /mnt
btrfs filesystem resize 2:max /mnt
if the disks contained any data then it would be wise to do a btrfs balance start /mnt but since they're empty i don't think it's needed
hexed isle
yes
solid granite
nice
hexed isle
created + mounted subvols
solid granite
@ is at /mnt and @home is at /mnt/home?
solid granite
that won't work
solid granite
you need to umount /home
hexed isle
and then?
solid granite
it probably failed because the directory you're trying to mount it to doesn't exist
hexed isle
it did
solid granite
so you need to mkdir /mnt/home
hexed isle
alright done
solid granite
okay
also don't forget
mkdir /mnt/boot
mount /dev/nvme0n1p1 /mnt/boot
i think that was the esp partition
and swapon both of your swap partitions
hexed isle
i did
and now
im having another problem yaaayyyyyyyyyy

hexed isle
however it's there already and you don't need to install anything extra
machine-info isnt working and thats a command bundled with it according to the arch wiki

well the difference is that grub is more automatic and abstracted, systemd you got to manually edit some files
machine-info I believe won't work in chroot, I think only on the archiso before you chroot
hexed isle
not working there either weird
sturdy parrot
maybe they mean etc/machine-info that you can cat?
although I don't have it locally
I wrote this little guide if you wanna follow the sections inside systemd boot https://github.com/yenaras/laptop.config/blob/main/docs/systemd_arch_install.md#systemd-boot

no i already mounted everything including the root
i did
this is the part i havent done
sturdy parrot
That's the number you get with yhe command
I'll show you mine
can you show me lsblk -f
sturdy parrot
yes
hexed isle
the hash is supposed to be replaced with partuuid ohhhh....
sturdy parrot
and make sure you have a space and rw after
hexed isle
what is this stuff do i need it
sturdy parrot
no you don't need it
it's just some kernel parameters I set
you can look into them in the wiki if you like
sysrq=1 is good to have, it allows you to reboot safely with a special key sequence if you get in trouble
<alt>+<sysrq>+REISUB (reboot even if system utterly broken)
hexed isle
how do you keep partitions mounted after rebooting
sturdy parrot
don't reboot now
hexed isle
i know
sturdy parrot
once it's installed, your fstab will handle that
hexed isle
oh right i havent done fstab yet
sturdy parrot
/etc/fstab defines what mounts on boot
did you do genfstab -U /mnt > /mnt/etc/fstab before you chrooted?
anyway the fstab won't be loaded from the live usb, only on your hardware when you are done
hexed isle
did you do `genfstab -U /mnt > /mnt/etc/fstab` before you chrooted?
ok ill do that
sturdy parrot
you have to exit chroot to run that cmd
hexed isle
i did
sturdy parrot
kk
hexed isle
thank you so much for your help btw

I can help more in like an hour when my son goes to bed if needed
hexed isle
are those tabs or spaces? can i just have a normal space between each key and value?
sturdy parrot
You can use tab or any number of space, I just like them lined up
hexed isle
these two packages return error: target not found
sturdy parrot
It's an old guide, I need to make a new one
I'm not even on Wayland anymore
And my son broke that laptop
I'm on xorg i3 on my desktop
I don't recommend you start with sway and Wayland anyway
pavucontrols should work though
But I would use pipewire over pulse audio
Maybe do KDE or Gnome or XFCE for your desktop, follow the arch wiki for this bit
Maybe tonight I'll write a guide for my current setup
sturdy parrot
Oh typo on my end for pavucontrol
And rhe other one should be xorg-xwayland, but I don't recommend Wayland unless you are really experienced with Linux and want to test it's readiness. It's still in it's infancy

Manual arch install
lsblk returns a different uuid than findmnt -fn -o PARTUUID /dev/<root-partition>
sturdy parrot
yeah but use the one from findmnt
lsblk -f shows UUID which is different than PARTUUID
check blkid | grep /dev/<root-partition>
you can see both that way too
you could specify with the UUID but PARTUUID is less likely to change
hexed isle
you could specify with the UUID but PARTUUID is less likely to change
i did... it said waiting 10 seconds for device
mounting on real root
cant find
failed to mount
now being dropped into emergency shell
sturdy parrot
when you used UUID?
or PARTUUID
because you need to make the key the name of what you use
UUID or PARTUUID
also check your fstab
if there are double entries on your fstab, you will get errors like that
hexed isle
because you need to make the key the name of what you use
ohhhhhhhhhhhhhhhhhh
well because im using btrfs i was thinking uuid would be better
hexed isle
ok i used the uuid
i just changed the key to UUID
error: root device mounted successfully, but /sbin/init does not exist
@sturdy parrot
sturdy parrot
chroot in from live usb and run mkinitcpio -P
hexed isle
understood sir
i thought i didnt need to do that because the wiki said it was already ran upon installing the packages
but ill do it now
sturdy parrot
sometimes it's necessary to do it again
not sure what happened in your case
I have to run it every time I update the kernel and nvidia drivers, using a pacman hook
I guess I don't manually run it, the nvidia.hook does it for me lol
good thing to do on a fresh install while chrooted in is to run pacman -Syyuu
or if you make it to live system, either or
hexed isle
I have to run it every time I update the kernel and nvidia drivers, using a pacm...
how do i install nvidia drivers
sturdy parrot
do you have an nvidia gpu?
hexed isle
yes
sturdy parrot
sudo pacman -S nvidia nvidia-utils
in that case you should also use the pacman hook
sturdy parrot
wth
add this to your arch.conf init=/lib/systemd/systemd
after your UUID and before rw
nvm that's an old answer on stackexchange
does it say this? ```
/dev/sda2: clean, 59309/14622720 files
ERROR: Root device mounted successfully, but /sbin/init does not exist.
Bailing out, you are on your own. Good luck.
sh: can't access tty: job control turned off
[rootfs ]#
YES
sturdy parrot
/sbin/init is a link to /lib/systemd/systemd
even if you link that, I think something else will be broken
did you pacstrap base?
hexed isle
i did
sturdy parrot
maybe just pacstrap it again
hexed isle
WIAT
sturdy parrot
and base-devel
hexed isle
DO I NEED TO PUT MY MOUNT POINT IS A PARAMETER TO PACSTRAP
sturdy parrot
yes
well
you need to put /mnt
pacstrap /mnt base base-devel linux linux-firmware just try that again
it shouldn't hurt anything
with everything mounted of course
To be fair you aren't that far in tbh, restarting and taking notes is what I did starting out years ago
And why do you want btrfs
Even though that's not your issue, I'm just curious
Is it a RAID volume?
hexed isle
And why do you want btrfs
so i can extend my disk to another one
hexed isle
`pacstrap /mnt base base-devel linux linux-firmware` just try that again
gotcha
sturdy parrot
oh i see
hexed isle
oh i see
root device mounted successfully, but /lib/systemd/systemd does not exist
everything works fine its just this one init file or whatever
sturdy parrot
root device mounted successfully, but /lib/systemd/systemd does not exist
"This usually happens because you're mounting the wrong partition as "root" in the kernel command line." https://bbs.archlinux.org/viewtopic.php?id=219102
actually go ahead and mount how you normally do and then show me lsblk
from archiso
ping me when cuz I'm working on an app
hexed isle
alright
sturdy parrot
what really helped me when starting with arch linux and learning linux in general, I had arch already set up on my desktop but you can have anything and do this. I was installing it to my laptop and would ssh to the laptop for set up. I messed up a lot of things. So I would write github markdown files documenting the process. Thus the guide I shared you. I feel like documenting your process is an important thing that we overlook and skip a lot in tech but it helps so much. I should document more now, but I'm telling you it helps a lot if you document stuff yourself while you are doing it
hexed isle
this is kind of a makeshift documenting place
sturdy parrot
yeah but it can get lost quick later
you should document stuff on your own somehow
even write stuff down on paper at first
I found md files are great for documenting stuff
especially atm I'm building an industrial maintenance work order system, and I plan to build a wiki for certain tasks
hexed isle
actually go ahead and mount how you normally do and then show me `lsblk`
say no more
@sturdy parrot ok master chief heres the lsblk -fa
hexed isle
the reason im using uuid instead of partuuid is because i thought there may be a compatibility problem with the btrfs file system and i dont think the uuid would change for that anyway

/boot/loader/entries/arch.conf
sturdy parrot
You mounted /mnt and /mnt/home on the same partition. Did you want a separate home partition? If not then you just mount /mnt and not /mnt/home
And if you want home on a separate partition, you'll have to make a new partition
Maybe it's a btrfs subvolume thing?
solid granite
it is
hexed isle
look man i just need to figure out whats up with this sbin init shit
if i could find that everything would be smooth sailing
hexed isle
/sbin/init not found...
sturdy parrot
it's something to do with your mount point for root when you pacstrapped the system.
sturdy parrot
```
mount /dev/nvme0n1p1 /mnt # mount the root subvolume (meaning without a s...
you didn't cd back out of /mnt before mounting your subvolumes to /mnt again
oh actually try adding rootflags=subvol=@ to your options in /boot/loader/entries/arch.conf
seems some extra steps are needed for btrfs setup
your default subvolume needs to be @ and not @home
sturdy parrot
@hexed isle did you get it sorted out?
hexed isle
<@522970788203069442> did you get it sorted out?
im turning it on and trying it
very sorry about all of this i wouldve been done 3 days ago if it wasnt for this wack config
sturdy parrot
all good, btrfs seems like an extra learning curve lol

and then what do i set my init to again
