Hi!
Due an hibernation event my BTRFS Raid56 failed and is not mountable
anymore. :(
For Debugging I moved the Devices to an test-hardware and booted this
system from an Arch Linux ISO, which I created for this purpose.
The Problem is:
[ 1086.714109] BTRFS (device sdd1): parent transid verify failed on
209362944 wanted 293924 found 293922
Is there any posibility to recover any files from this desaster?
Is there any posibiolity to set the superblock to transid #293922 ?
See my tries to recover here as konsole log below.
