       There is an issue when releasing a file striped with DoM after an hsm_restore.

      To reproduce:

      1) create a file with a 1st component on MDT:

      lfs setstripe -E 1M -L mdt -E -1 -S 4M -c -1 /mnt/lustre/domfile

      2) archive and release the file (requires HSM set up)
       

      lfs hsm_archive /mnt/lustre/domfile
# (wait for archive to complete)
lfs hsm_release

      3) restore the file

      lfs hsm_restore /mnt/lustre/domfile
# or cat /mnt/lustre/domfile

      4) release the file => FAILS 

      lfs hsm_release /mnt/lustre/domfile

Cannot send HSM request (use of /mnt/lustre/domfile): Device or resource busy

       
      It may be something wrong with the data version stored in hsm EA.
