Hi all,

 

my unraid has 8 identical disks, 1 parity and 7 data disks. One disk always had issues spinning down and i messed up while beeing tired and doing just quick search .. and executed most likely the wrong commands. So maybe it is too late, may you can help me.

 

if i am not wrong i ran first xfs_repair -nL /dev/sdg and after that xfs_repair -L /dev/sdg..  with no superblock found at the end. 

so i formatted the disk and brought it back into the array, assuming parity pair will restore the data -> boom, parity valid ... empty disk.

 

any idea how to restore some of the data ?

That not the correct command, see check filesystem for the future.

Didn't you see the warning?

 

The only option now is restoring from a backup, if there's no backup you can try a file recovery app, like UFS explorer.

ok, thanks - as expected .. just beeing tired. thank you

 

now the parity check has to apply a lot of corrections
