Sorry, I have to correct this:  "the nodes CANNOT 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.
