Hello everyone!
I'm hoping someone can help me save some important personal files. After a strange power failure yesterday (voltage dropped from 230 to 40V) I can't mount my storage.
What I've tried:
cryptsetup luksOpen /dev/etherd/e0.1 xellos8tib
This step works fine. But after that I get this:
mount /dev/mapper/xellos8tib /home/snix/Xellos
mount: wrong fs type, bad option, bad superblock on /dev/mapper/xellos8tib,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
Then
dmesg | tail
btrfs bad tree block start 9057752897035855649 1209453043712
btrfs bad tree block start 13993224894159572068 1209453043712

and

Have tried searching for a solution but have so far failed to find anything helpful (at least to my limited understanding). Any ideas? Or is my data doomed?

Since the main problem with btrfs atm is that there isn't a version of fsck that can fix errors, your best bet would (imo) be to simply wait for such a version.

I guess I'll have to do that. Got about 5.2TiB of data on that array. Lots of photos and videos from travels, writings, old school work (I save everything I produce), ideas, e-mail going back over 10 years. Used btrfs because I have better experiences with it than I have with ext4 when it comes to sudden power outages. That was apparently a bad choice. This sucks
Anyway, thanks for your time and sorry for the whining ^^
If anyone else has a solution I'll keep an eye on this thread. Hopefully I wont have to wait too long for fsck to start working.
