[Lustre-discuss] Problems with failover

[Jeremy Mann]

We have come across two situations where we've had to rebuild our Lustre
filesystem. Both happened when one of the OSTs hard drives failed. We
did set the OSTs up for failover, however the network was never
interrupted so the switch to the failover node never happened.

How exactly should failover work?

We are running 1.6.0.1 on 20 OSTs and one dedicated MGS/MDT.
