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!
