[SOLVED] How to restore home subvolume

I tried to restore snapshot of home subvolume, but when I'm trying to rename broken subvolume, it returns this message:

$ mv @home @broken                                                                  
mv: cannot stat '@home': No such file or directory

. Do I need to rename home directory or anything else?

Re: [SOLVED] How to restore home subvolume

Are we talking 'btrfs' (not using it myself but), what's the output of

# btrfs subvolume list -p /home

?

sudo btrfs subvolume list /                                                                                                                                                           1 ↵

Re: [SOLVED] How to restore home subvolume

$ mv @home @broken

suggests you're not issuing that command as root (from '/') - which you shouldn't, anyway - and there is no '@broken' subvolume listed above... EDIT: sorry, that's bs...

But please wait for a response of from a more qualified user that's actually using 'btrfs' before taking any further action.

Reason for last edit: grammar

Re: [SOLVED] How to restore home subvolume

@home can be replaced but not while it is mounted.

To manually restore @home:

Boot into a live USB, for example. Mount the partition containing the Btrfs pool. Move the corrupt subvolume with "mv ..." or with a file manager to somewhere on the same partition. Create a writable snapshot (@home) from a good snapshot with "btrfs subvolume snapshot ...". If necessary, update the subvolid in the etc/fstab file located in the root (@) subvolume. After everything is successful, delete the corrupt subvolume.
