After upgrading to Lustre 2.12.8 I found that the first mount after
a reboot behaves differently:<br>
<br>
Mounting mds02/astro0 on /mnt/lustre/local/astro-MDT0000<br>
mount.lustre: mount mds02/astro0 at /mnt/lustre/local/astro-MDT0000
failed: No space left on device<br>
<br>
And a different syslog output (attached syslog-0).<br>
<br>
Doing the mount again has this error:<br>
<br>
Mounting mds02/astro0 on /mnt/lustre/local/astro-MDT0000<br>
mount.lustre: mount mds02/astro0 at /mnt/lustre/local/astro-MDT0000
failed: File exists<br>
<br>
And a syslog like the one first posted. Attached the new output in
syslog-1.<br>
<br>
Finally, stopping Lustre (Only MGS in this case) and the lnet
service does free resources making lustre_rmmod fail:<br>
<br>
# lustre_rmmod <br>
rmmod: ERROR: Module osp is in use<br>
<br>
<br>
Cheers,<br>

Forgot to say this is Lustre 2.12.6 and CentOS 7.9
(3.10.0-1160.6.1.el7.x86_64).<br>

<br>
A reboot of the MDS stalled and got forced reset. After that the
MDS would not start. The syslog is attached. <br>
<br>
I'm not sure what the "class_register_device())
astro-OST0002-osc-MDT0000" part is supposed to do but
astro-OST0002 is not mounted at this time. I guess this comes
from the MGS. <br>
