Dear Lustre Users,
we have some files in the system, that are not writable anymore. Symptoms:
- normal rm fails: rm: cannot remove 'file': Operation not permitted.
- lfs rmfid fails without error message. The file is just not deleted.
- lfs migrate fails: file: no write permission, skipped
- all commands are executes as root on a node which is listed in
nosquash_nids.
- other files with the same permissions located in the same folder are
writable.
- the affected file are readable. Creating a copy is possible, but
deleting the original file not.
- the problem remains after running lfsck.
We use Lustre 2.12.5 on Centos 7 with ZFS backend.
Has anyone had such issues before? Any ideas how to delete these files?
Thank you!
Robert
