Hello,

I’m having some issue whenever I’m trying to reboot or shutdown my pc.

Here’s some specs about my computer:

  • Dualboot with windows
  • External hard drive with btrfs in
  • The windows installation was set on top of my manjaro
  • Kde for my desktop environnement

The message that I get :
Failed to remount root and kernel file system - btrfs
Failed to remount root and kernel file system - btrfs
(I got it twice)

I’ve already try to remove the “space_cache” option as I saw on other threads that had the same issue.
I’ve try to upgrade my grub.
I also try to add my ntfs partition “sdb3” (that is my windows partition).

But none of the solutions that I saw worked for me.

I’m asking for help :slight_smile:

PS: Sorry for my english.

2

did you set your cache ti this: space_cache=v2
did you tried checking your hard disk for errors

3

I’ve tried the space_cache=v2 but it doesn’t work.

You mean to do a checkdsk to see if there is any wrong blocks ?

4

yes try check your disk for errors…

You find good Information about Btrfs in the wiki

mhwd-kernel -li :

The following kernels are installed in your system:
   * linux54

Maybe, It’s my kernel that doesn’t support the 'memory_recursiveprot’

I’ll try to upgrade my kernel to 5.7 to see if it works.

7

Try 5.10 and/or 5.15

5.7 is not a supported version and end of life.

8

I’ve try the 5.10 since it’s an lts version and it seems to works.

But still got some issue while I’m rebooting my computer but no message appear on my screen.

Here’s the error that I get :

journalctl -p 3 -b :

I think that my drivers are little bit messed up ahah.

Thanks for the help btw, It’s really appreciate :slight_smile:

Ok, the issue was resolved by just upgrading the kernel.

When using btrfs →

I would suggest to use the newest possible lts-kernel
