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.
The failure of the copy process is a timeout issue ?
How can I change the timeout ?
Thanks !!!
Cheers, Stefano

More important is to include the crash message from the client and
the version of Lustre you are using.

Hi,
I have a small problem but it certainly is the fault of the little
knowledge I have by the argument.
I have a Lustre file system with a node MGS/MDS, two nodes OSS and
one Client.
I launch a copy of a large file on Lustre and while the copy goes on,
I restart the node OSS that is handling the writing on the File
System.
The copy process is put in the state -stalled- and when the node
OSS is back on,
I expected the copy process to resume normally, but instead crashes.
This is a log on the node MGS:
