BTRFS and Timeshift ERROR only ubuntu-type layouts with a and ahome subvolumes are supported

[drowsy ibex]

Yeah so what Timeshift is asking for is for at least your home subvol and your root subvol to be named as they are most commonly;

@ for your root subvol
@home for your home subvol
@<subVolName> for the rest

So you can check in the script for where they created the subvolumes and see if they follow these names

i checked the script and it seems to match my current setup

not really sure what needs fixing here

https://i.imgur.com/URvRupO.png

it seems like it matches 1 to 1

from what i read in the documentation it seems like all the important was created as a sub volume

[weak vessel]

oh no no no

dont use a @tmp subvol

/tmp is better with tmpfs instead

which is already done by default

[weak vessel]

same with var
/var/lib/pacman
is where pacman stores its list of packages
and their versions
if you seperate that from root

that's very bad

cus if your restore a snapshot of root but dont restore var to the same time as the root subvol

pacman will think your packages are upto date even tho they arent

and any installed packages that was uninstalled and restored root subvol
(pacman will think that it's still there even tho it's not)
or you installed a package and restored root subvol
(pacman will think it's no longer there but in reality the files are still there)

@compact radish i recommend you use a better layout of subvolumes

something like
root home var/log snapshot
is sufficient

[weak vessel]

someone should tell this to chris titus

that layout can really mess up if people dont know what theyre doing

[compact radish]

ooh shit

[compact radish]

@weak vessel can i get some commands brother?

[weak vessel]

welp
youre better off reinstalling at this point cus you have to do alot of moving

[compact radish]

oh man am i that fucked

that really sucks been using this setup for a couple months now

[weak vessel]

it's fine
just
remember to snapshot @var if you snapshot root

[compact radish]

well it explains why ive been struggling with btrfs lol

[weak vessel]

and restore @ the same time as you restore @var

[compact radish]

https://github.com/ChrisTitusTech/ArchTitus/blob/main/scripts/0-preinstall.sh here is the link to the github page, im probably not gonna tell him because i got alot of figuring out to do

[compact radish]

https://ask.fedoraproject.org/t/qemu-virtmanager-in-combination-with-btrfs-and-timeshift/25365/6 this was the method i used to save my vm, would it be possible to bring the snapshot of the vm over to a fresh install ?

[weak vessel]

do you still have a snapshot from when you first installed? or no

[compact radish]

naw it was just one i made recently

[weak vessel]

oh wait i misread

[compact radish]

so i can protect the vm's from timeshift

[weak vessel]

youre saying you want the vm diskfile to not be snapshotted

[compact radish]

pretty much

[weak vessel]

just make a subvolume for /var/lib/libvirt
this will make it get excluded from the snapshots of @var

[compact radish]

sweet

i already did that

[weak vessel]

wait
does timeshift create snapshot for @var?
i dont really know since i dont use it
if so then youre fine (im talking aout the first problem btw)

[compact radish]

i'm still learning about timeshift and btrfs so no idea, i just know timshift kept messing up my vm's

so i had to get it to stop bullying them

basically put in it in a sub volume to quarantine it from the rest of computer

whats the fastest way to unfuck myself here? if you have a decent install script that's gonna unfuck me up id be more than happy to use that. (just as a time saver)

[weak vessel]

cant make one rn
im busy
probably tmrw or overmorrow

[compact radish]

its okay no rush, im probably gonna work on it this weekend

this seems like one of those time consuming blackhole problems where you start early in the morning and you look up from your computer and its 2am and the dog has to take a shit

but thank you for helping me out, its been struggle to try and figure out btrfs

[compact radish]

im guessing just forking christtitus script would be fastest method

[drowsy ibex]

Can u not move the VM disk file to somewhere else

And then btrfs sv add ...

[compact radish]

I can but i think it should be fine as is. Worse comes to worse i can move it to an external drive.

[drowsy ibex]

Ye that works also

@var isn't best ngl

It can break stuff if u revert to an older snapshot with a newer /var

I would recommend /var/log

[compact radish]

var/log ?

wait

nvm its in my linux book

would /var/log save all my dot files?

I have my computer set up to where my work flow is really nice would like to have to keep that way

[drowsy ibex]

Dotfiles are best on github

Setup a dotfiles folder in your home folder and use symlinks to link them back to their original locations

Dotfiles are not in /var/log, they're usually located in ~ or ~/.config

[compact radish]

woe cool idea I'll definitely start working on that

[weak vessel]

💀 that's what i said above

[weak vessel]

@compact radish
here's the modified version of archtitus' 0-preinstall script

if you wanna know what i changed
here's the diff

[compact radish]

thank you so much!!!

[haughty mesa]

i0bz received a thank you cookie!

[compact radish]

im gonna take a look into it

i have some time today to work on my linux stuff i wanted to see if i can save my configuration before i do reinstall

also

going to post this script to archtitus github

[weak vessel]

oops
i think i missed a comment there
oh well it's just a comment

[compact radish]

so question for ya which way you think is best way to run this ? i was thinking of throwing it in github and then doing a git at the start like i did with the other script, you think that would work?

[weak vessel]

yeah that would work

wait i dunno if there's other scripts that it depends
cus i just changed some lines in archtitus's 0-preinstall.sh

you should fork his repo and put the changes for your own

[compact radish]

definitely will thank you!

[haughty mesa]

i0bz received a thank you cookie!

[compact radish]

Im probably gonna post this code in issues just so he can make the adjustment

[sonic egret]

ID 256 gen 9316 top level 5 path @
ID 257 gen 9334 top level 5 path @home
ID 258 gen 9282 top level 5 path @snapshots
ID 259 gen 9331 top level 5 path @var_log
ID 260 gen 9275 top level 5 path @var_cache

better setup?

[weak vessel]

eh sure
there's barely anything in /var/cache for me tbh so i just ignored that

[sonic egret]

ahhh just saw underneath you proporsed the same

[sonic egret]

lazy.

[compact radish]

lol erm all good?

[compact radish]

working on this atm.

[compact radish]

Getting a PXE over PV4 error

Mmh not sure how to get to my boot menu from here 🤔

[weak vessel]

when booting to the iso?

[silver quiver]

also, try dotter
https://github.com/SuperCuber/dotter

[compact radish]

Yes after installation

[weak vessel]

PXE over IPv4: Means What? This message pops when your computer cannot start from your drive. It happens due to incorrect BIOS configuration. You will see this error message when other booting devices are unavailable

this us the only thing i can find abiut that error

[compact radish]

I thought it meant secure boot was enabled but I checked all the bios settings and it seemed fine

[compact radish]

https://github.com/thealmanac1/ArchTitus/tree/main/scripts

[weak vessel]

btw youre using uefi right?

and not legacy bios

[compact radish]

Yep

[weak vessel]

other stuff i found in the internet says it's related to legacy

[compact radish]

Mmh maybe I should double check that but its fucking with me abit i swear only my desktop is has a legacy setup

[weak vessel]

culd oyou also show me the bootorder

[compact radish]

Yeah sure one sec

Hanging charging my laptop

Secure boot is disabled

Im gonna try and install the script arch titus again. To see if its a problem with the code or the computer

Okay i have vm settings enable maybe its that?

[compact radish]

No fuckin idea

[weak vessel]

ok ik what it means now

It's probably trying to boot into an internet drive

[weak vessel]

disable the ipv4 pxe boot first

cus it's first in the boot priority

[compact radish]

Okay 👍 I’ll try that

Mmhh its not letting me boot from the usb

I just get a screen flikr

Just gonna give it a few minutes

[weak vessel]

wait
how are you trying to boot into it btw?
are you just plugging it in and just opening it?

youre not opening the boot menu?

the boot menu for the ideapad is f12 or fn f12
spam that while booting
it should give options as to where to boot

[compact radish]

Been pressing f12 to get to this boot menu

Screen just flickers when i select load from usb

Mmh i think im fubar

[weak vessel]

hmm did you not flash anythinng on the usb?

[compact radish]

Nope

I think im gonna us a rescue cd
