<br>
We recently attempted to add several new OSS servers ( RHEL 8.7 and <br>
Lustre 2.15.2). While creating new OSTs, I noticed that mdstat reported <br>
some disk failures after the mkfs, even though the disks were functional <br>
before the mkfs command. Our hardware admins managed to resolve the <br>
mdstat issue and restore the disks to normal operation. However, when I <br>
ran the mount OST command (when network had a problem and mount command <br>
timed out), similar problems occurred, and several disks were kicked <br>
out. The relevant /var/log/messages are provided below.<br>
<br>
This problem was consistent across all our OSS servers. Any insights <br>
into the possible cause would be appreciated.<br>
