[lustre-discuss] ost_connect to node failed

[Hallstein Løhre]

Hi,

After some trouble with runaway processes yesterday, I had to reboot several Lustre clients. Now some of these shows the following entries in /var/log/messages:

Nov 25 11:09:51 nodexx kernel: LustreError: 11-0: lustre01-OST000a-osc-ffff887ee3207800: operation ost_connect to node 192.168.1.xxx at o2ib<mailto:192.168.1.xxx at o2ib> failed: rc = -114

The filesystem seems ok, but the stuck processes might have accessed file(s) on OST000a. No hardware problem seems to exist, the ost's are all zfs volumes with status ok.
I suspended writing to ost000a, but after reboot of the clients and checking for hardware problems, I have reenabled writing.
Any explanation of rc = -114 ?


Best Regards

Hallstein Løhre
