two nights ago restarted my laptop and it would hang on trying to mount /home partition, wouldn’t go into emergency mode. Just sat there. After getting gnuparted live and finding a few forum posts i was able to get /home to mount.
after getting back in it’s apparent that my data was corrupted. Worse certain things don’t seem to be saving.
Such as my Favorites in Gnome on the sidebar are gone. When I try to drag over anything it just says added to favorites. They don’t appear on the sidebar. Another example, terminal won’t allow me to change the colors??? Even weirder… my previous settings show as the current selection (green text black screen) but i can’t uncheck use system theme. I can create folders though. I’m hoping there’s another trick in the btrfs toolset. I looked at their wiki but the documentation doesn’t appear to match my version.
- Is there a way for btrfs to recover this data? My current version is Btrfs v3.12+20131125
I’m getting a lot of this in dmesg:

- If there’s not, there isn’t a #2. I wipe out completely and reload from scratch. The drive tested out fine via diagnostics.

Hi
Hopefully you enabled snapshots of your /home since your running btrfs?

snapper gives “unknown config”
I see there are options for btrfs restore to try and salvage data. Just not sure which commands I really need to use and documentation has different options than i see with btrfs --help.

Hi
But during the install did you create a /home subvolume or not?
You could check in /.snapshot/<some_number>/snapshot/home is your user
there?
