[Lustre-discuss] OSS server

[Stefano Elmopi]

Hi,

sorry for the delay of my reply.
I have explained myself badly, I have tried with success the scenario  
of OSS failover,
but If I have a simple scenario with one MGS/MDS and one OSS, without  
failover,
and the server OSS crash, how can I recover the data stored on the  
OST ??
Simply replace the server root with one that has the same IP ??

Thanks

Yes.  This is called "failover".
