[Lustre-discuss] Recovery Problem

[Stefano Elmopi]

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
