I also tried "btrfs-select-super" from git on all disks (sdb1,sdc1,sdd1=
) with "-s 1" and "-s 2" and nothing helped.

Only one good thing is that this is "backup machine" so I can tranfer a=
ll data from "main machine". But it is 3TB so it would take about 40day=
s to fully transfer all data :-(

Is there any possible way to (partially) restore some data? (I use rsyn=
c syncing data between both machines)
