[SOLVED] i set up a BTRFS partition for use in windows and now i cant boot up arch how do i fix this

[coarse kindle]

Could you please boot into the Arch Live ISO, and execute the following commands?

lsblk -f | curl -F 'f:1=<-' ix.io

Afterwards please mount and chroot into your OS file system, then execute

curl -F 'f:1=<-' ix.io < /etc/fstab

[little garden]

basically what is being said above is that it seems incredibly likely that /mnt/shared in fstab is relying on an incorrect UUID.
Perhaps the partitions have changed?
If the partition that moutns to /mnt/shared no longer exists, chroot in and delete it from /etc/fstab, if it does, check the UUID matches what is in fstab. If it still does, then do other parameters, like the filesystem, match up correctly?

doing the above commands and giving us the output (you'll need an active internet connection) will let us know

[broken echo]

sorry for late reply, here you go

[broken echo]

i did delete a partiton, maybe i forgot to change the fstab and now its expecting a partition that isnt there?

[little garden]

lol, we'll need the links it spits out

[little garden]

that's almost definitely what is happening

[broken echo]

how do i fix this, doctor?

[little garden]

/dev/nvme1n1p2 /mnt/shared btrfs sync,users 0 0
does that have subvolumes?

(also what is on it?)

[bright quarry]

tbh, I'd just boot the iso, mount everything and regenerate it

[broken echo]

the partition i deleted was a btrfs partition, i now have no btrfs partitions on my ssd

[little garden]

I mean if that line is depreciated just comment it out of the fstab

[little garden]

yeah just comment out that line in the fstab then

I'm guessing p2 is now just free space

if you're confused:
iso
mount /dev/nvme0n1p4 to /mnt
<editor> /mnt/etc/fstab
comment out the line above that we specified as no longer applicable
save
quit
reboot without iso
should work.

If you're not sure what to do for <editor> just use nano

[broken echo]

that worked, thanks

vegancookies received a thank you cookie!

[broken echo]

i guess ill stay away from btrfs from now and just use exfat

[little garden]

this wasn't a btrfs issue, but I'm also not sure what you were trying to use p2 for

[broken echo]

a btrfs partition to use in both windows and arch

[little garden]

I don't understand why you'd want that to be btrfs

you're right that exfat will be the best one compatibility wise though

[broken echo]

i asked in this server and someone told me exfat is depracated

[little garden]

what did they suggest instead?

[broken echo]

btrfs

[broken echo]

umm

with an existing exfat partition, this still occurs

[little garden]

can you show us the /etc/fstab again?

(and the lsblk)

[broken echo]

http://ix.io/4CY1

[little garden]

that edit after I click, lol

did you make a new parttion for p2? I don't know what p2 is?

maybe fdisk /dev/nvme1n1 with the p command can tell us?

[broken echo]

yeah, i said i made an exfat partition

thats supposed to work across windows and arch

[little garden]

I don't understand why it doesn't appear to have a uuid

when you're next in chroot do ls /mnt/mntjust to make sure /mnt/shared exists as well

[little garden]

okay cool

didn't know you were chrooted

can you show the fdisk command output?

[broken echo]

fdisk -l
?

[coarse kindle]

btrfs filesystem show | curl -F 'f:1=<-' ix.io

[little garden]

^

[little garden]

they deleted the btrfs partition

You won't need sudo of course, and you won't be doing /dev/sda

[broken echo]

its where the aformentioned windows install is installed

[little garden]

oh it's 0n1 that you want, okay

/dev/nvme1n1p2 /mnt/shared exfat sync,users is in your fstab

change it to be the other nvme device 😂

you've exited fdisk without editing anything in there right?

(p doesn't edit anything)

if not, ctrl + c

just change the fstab to be the correct partition of the correct nvme device

[broken echo]

i used kde partition manager. guess ill manually edit fstab next time

[little garden]

this is why I prefer to use uuid's, devices are very easy to mess up

[broken echo]

btw it works now, thanks again

[little garden]

I meant just now, but cool

[little garden]

this being the wrong device is why the btrfs one just completely failed by the way

@coarse kindle why fs would you suggest for a shared partition that will be used by both windows and linux?

[broken echo]

i was the one to come up with that idea

[coarse kindle]

Did you mean "What fs"

[little garden]

yes, sorry

[broken echo]

i have a local music library that gets updated often, so i want something that can be used by both oses

[little garden]

do both need to write to it?

[coarse kindle]

Unless UNIX permissions and snapshots are required, I would suggest extfat.

[little garden]

@broken echo who told you not to use exfat?

[broken echo]

no, but arch is installed on an ext4 partition and i cant be bothered to reinstall

[coarse kindle]

However, there are other ways to use common Linux filesystems in Windows, such as using WSL2.

[little garden]

exfat seems like the right choice, would love to know who said not to use it. But also:

... solved
