Hi, We took three RHEL 7.2 boxen and deployed Lustre 2.8.0. When we have a joint MGS+MDT on the same block device we can failover our OST's between the OSSs. However when we tried to having the MGS and MDT on separate block devices (still on the same server) failover hangs. Can you offer any assistance or advice?
