I guess I borked my System (lemmy.today)

Context: I updated my CachyOS (Arch) BTRFS system. Some new things caused few problems especially brave browser(missing tabs), some icons missing.

So I wanted to go back to previous snapshot.

What I did: I first restored my home subvol which I saved before update. I worked.

Then I tried to restored my root partition. This is where I got the problem.

I got this error.

1001090084

I would really appreciate URGENT help

If you need any more details I can provide.

EDIT

I used BTRFS Assistant to restore the root partition. And I did it while the OS is running.

( I previously did that and got no issues )

I pressed crtl+d and got 👇🏽

I typed my password and went into maintenance. Typed journalctl -xb and got 2667 lines 😵‍💫. While scrolling mindlessly, this looked like something 👇🏽

This is my refind_linux.conf 👇🏽

Have you resolved it yet? First thing would be finding out why did it kick you into emergency mode ie whats the actual error

[–] gpstarman 2 points 4 weeks ago (1 children)

Not yet.

I kindly request you to see the edited post too.

[–] possiblylinux127@lemmy.zip 3 points 4 weeks ago (1 children)

What did you do before hand?

[–] gpstarman 1 points 3 weeks ago

If you mean to ask why do i have to restore snapshot in the first place, I updated the system. And I didn't like the new update. First thing I noticed is Brave replaced all my group tabs to new tabs. When I searched about it, I came to know it's a common , critical issue that still haven't been solved🤦🏽‍♂️.

Also Brave is now significantly slower now.

I also noticed few are wierd or not there at all. ( Plasma 6.3.1)

Put in your root pw and then look at the logs. You might need to mount disks to do so.

[–] harsh3466@lemmy.ml 1 points 4 weeks ago* (last edited 4 weeks ago)

This. Enter your su password and have a look at the logs. Likely something you can fix without tooucj trouble. I've run into this a few times over the years and I've always been able to figure out and fix the problem based on the logs.

Edit: removed incorrect instruction.

[–] possiblylinux127@lemmy.zip 4 points 4 weeks ago* (last edited 4 weeks ago) (1 children)

Please post more details

Also I don't want to be that guy but for me personally I would stick to the beaten path. Stick with the mainstream stuff that is stable and well tested. CachyOS is Arch based and does not have anywhere near the stability of something like Linux Mint.

[–] gpstarman 1 points 3 weeks ago

Yeah. I've been thinking about going back to Mint too. But the only thing stoping is that Arch is rolling distro. Which means I can get updates sooner. I mean linux gaming is getting better every day. I didn't like to be on lag for a year of improvements. Also Vavle investing lot on Arch.

I chose CachyOS, because it is made for gaming, it has decent GUI tools of its own and on top all that it's still Arch btw. So I can get benefits of Arch too.

Rolling distro can be both boon and bane. And now it didn't end up very well for me.

I saw similar error when I had a drive mounting line in /etc/fstab

When i commented out the line it went back to normal.

[–] moonpiedumplings@programming.dev 2 points 4 weeks ago* (last edited 4 weeks ago) (1 children)

Give us your fstab and lsblk.

Or, the specific piece of information I want is where the kernels are located. When /boot is part of the root subvolume (not the default setup, sadly), then the kernels will be snapshpotted along with the rest of the filesystem. /boot/efi would be where the efi system partition is, and where the bootloader is installed.

If /boot is instead the efi parition (default setup lmao), then this means that when you restored a snapshot of your root subvolume, your kernels were not downgraded. I suspect that older kernels attempting to read/view newer kernel modules would cause this boot failure.

[–] gpstarman 1 points 3 weeks ago

Short Answer: No, kernels are not snapshot ted

Long Answer: It's bit weird in my case.

Boot, EFI, Root are three separate partitions in my case.

Root mounts to /

Boot mounts to /Boot

Efi mounts to /boot/efi

It is this way because when I initially partitioned the EFI, I gave very less storage. But linux kernels are bigger than that. So, either I have move the partition. Which I didn't prefer because It'll take a lot of time and it said possibility of data loss.

So, I simply created new partition.

By default, CachyOS only snapshot /@ and /@/home. Which didn't include /boot because it's a separate partition it's own and not even BTRFS.

Start by following the instructions on the screen in order to get an error log.

[–] moonpiedumplings@programming.dev 1 points 4 weeks ago

If the root account is locked, which cachyos does by default, then you won't get anything from this screen.

I had to fix by usb booting and troubleshooting (a different issue though, I was playing with initramfs generation).

[–] SplashJackson@lemmy.ca 0 points 4 weeks ago (1 children)

Maybe try ctrl-alt-delete?

[–] gpstarman 1 points 3 weeks ago* (last edited 3 weeks ago) (1 children)

It simply restarts.🙂

Oh biscuits!
