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