Hi,
I realized that the time server differed much across machines,
there were at least a few hours of difference.
I'm doing the tests and have not been paying attention to time
synchronization
but now I have aligned the time of all servers and I've configured
ntpd service
and the problem no longer occurs.
I can imagine that the cause of the problem was just the time
misalignment.
Thank and sorry for the trouble !
Cheers, Stefano

Hi Andreas
My version of Lustre 1.8.3
Sorry for my bad English but I used the wrong word, "crash" is not
the
right word.
I try to explain better, I start copying a large file on the file
system
and while the copy process continues, I reboot the server OSS,
and the copy process enters state "- stalled -".
I expected that once the server back online, the copy process to
resume
normal
and complete copy of the file, instead the copy process fault.
Therefore the copy process that goes wrong, Lustre continues to
perform
good.
May 19 13:46:31 mdt01prdpom kernel: LustreError: 167-0: This client
was
evicted by lustre01-OST0000; in progress operations using this service
will fail.
The cp process failed because the client got evicted by the OSS.
We need to look at the OSS logs to figure out the root cause of
the eviction.
