Fwd: btrfs corruption

Fwd: btrfs corruption

[Riccardo Berto]

Hi
I'm a btrfs user since I encountered the ext4 3.6.2 bug and then I
decided to switch.

Today I was using my system when the /home btrfs filesystem get
corrupted. I rebooted almost instantly but it couldn't mount /home
(/dev/sda4). So I disabled the /home automount in fstab in order to
have gnome working again and I logged in to freenode on #btrfs channel
for having support of what was happened.
I met "darksatanic" who gave me suggestions to have /home mounted again.
I tried with him to mount /home manually with -o recovery (it didn't
worked). Then I did btrfs-zero-log /dev/sda4 and then it mounted, but
only a time. There were no files in there: only the dirs mountpoints
to my external HD. So I launched btrfs-restore /dev/sda4 /mnt/ and it
restored only some dotfiles (not all).
He then took me to write to mailing list attaching my logs, hoping for
someone with more clue who can help me.
