Hi,
We run a lustre 2.6 server setup (centos 6) with centos 7 clients
(2.6.92 / 2.7.0) for a while with no special trouble (except 2 ost
crashes with a kernel panic last month).
We recently installed machines with a newer kernel, and we needed a more
recent version of lustre client to successfully compile (2.7.65)
I'm facing a curious symptom on only one lustre client. Even with no
activity The log is full of :
LustreError: 11-0: lustre-MDT0000-mdc-ffff8805db669000: operation
ldlm_enqueue to node 10.0.1.60@tcp failed: rc = -14
What does it mean ?
The other 2.7.65 machines does not complain.
I can't unload lustre modules on this machine :
[root@node61 ~]# umount /scratch/
[root@node61 ~]# lustre_rmmod
