Problem with share


I’ve got two pools on BTRFS (data01 and data02). Recently one of my shares on data02 got damaged (i don’t now why, but it did). I can mount the pool and all other shares from that pool but not the damaged one, got the following error:

May  1 13:06:42 server1 kernel: BTRFS error (device sde): parent transid verify failed on 42936730058752 wanted 77177 found 78117

I would like to remove that damaged subvol, but when i invoke the command:

btrfs subvolume delete /mnt2/data02/someshare

i got following error:

ERROR: cannot access subvolume /mnt2/data02/someshare: Input/output error

The snapshot created before the volume got damaged is mountable without a problems.

  1. Is it possible to remove that damaged subvolume? I would like to replace it with snapshot
  2. Why rockstor is not mounting shares from second, good pool (data01)?
