Description

After a file has been archived and migrated, it's not possible to release it.

# dd if=/dev/urandom of=rand1 bs=4096 count=1024
...
# lfs hsm_archive rand1
# lfs migrate -o 0 -S 65536 rand1
# lfs hsm_release rand1
Cannot send HSM request (use of rand1): Device or resource busy

The file content is still accessible, and its hsm state is correct.

Yes, this patch is still useful. I didn't take the time to make the tests pass so it was missing reviews. I'll update the patch with your remarks and make the tests pass.

eaujames, courrier,
there is still patch https://review.whamcloud.com/35022 "LU-5896 hsm: can't remove a migrated file" open on this ticket. Is that patch still useful and should be refreshed, or should it be abandoned?
