You must manually mount them in only one place. When a failure occurs you have to manually mount the OST on the failover OSS (or have a piece of software do it).

Node00 is the mgs/mdt Node00 is the oss for ost0 and failnode for ost1 Node01 is the oss for ost1 and failnode for ost0 Both osts are on an SRP network and are visible by both nodes. Ost0 is mounted on node00 Ost1 is mounted on node01 If I try to mount ost0 on node01 I see in the logs for node00: kernel: Lustre: Denying initial registration attempt from nid 10.100.255.250@o2ib, specified as failover So do I have to manually mount the ost for failover purposes when there is a fail? I would have thought I mount the osts on both nodes and lustre will manage which node is the active node.
