Hi everyone,
I have a problem lately with our Lustre 1.8 deployment. It crashes periodically
in a way that the nodes can mount the storage and I can't access the Lustre
server machine neither. So I have to manually restart the machine every time to
make everything normal again. I tried to see the logs, memory usage and locks
count to see whether these issues may have the cause of the problem. But, I
don't think they account for this issue.
An interesting symptom I see every time this problem happens is the Infiniband
switch network usage lights which blink very fast. I think a huge traffic on
the Infiniband network to the lustre server may cause the server crash. Does
this relevance seems logical?
Anyway, I hope some of you may have experience this problem before and could
help me understand what is happening and how to avoid crashing the server again!
Thanks,
