File system no longer mountable #71

Description

@smurfix

I have a seven-disk BTRFS partition that is inaccessible after one drive disconnected itself (loose cable).
After reattaching it and rebooting the host, this happens:

s-bed ~# btrfsck /dev/nbd0
Opening filesystem to check...
parent transid verify failed on 108791845535744 wanted 731540 found 731528
parent transid verify failed on 108791845535744 wanted 731540 found 731528
parent transid verify failed on 108791845535744 wanted 731540 found 731528
Ignoring transid failure
ERROR: root [1 0] level 0 does not match 1

Couldn't read tree root
ERROR: cannot open file system

… so now what do I do, other than mkfs.btrfs? The thing is large and would take weeks to restore …
