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:
