Hi,

Rolling upgrade from Lustre 2.4.2 to 2.5.1 is supported and tested, allowing individual servers (or their failover partners) and clients to be upgraded one at a time without stopping the Lustre file system. The upgrade path is OSSs->MGS/MDS->Clients.

Best regards,

Yu, Jian

I would in general like to know what upgrade procedures are.

(and am also curious about 2.4.2 > 2.5.1)

Thanks,

Eli

OSS -> MDS/MGS -> clients as in the following attempt:
