Greetings, I am attempting to add mds failover operation to an existing v1.8.4 filesystem. I have heartbeat/stonith configured on the mds nodes. What is unclear is what to change in the lustre parameters. I have read over the 1.8.x and 2.0 manuals and they are unclear as exactly how to enable failover mds operation on an existing filesystem.
Do I simply run the following on the primary mds node and specify the NID of the secondary mds node? tunefs.lustre --param="failover.node=10.0.1.3@o2ib" /dev/<mdt device> where: 10.0.1.2=primary mds, 10.0.1.3=secondary mds All of the examples for enabling failover via tunefs.lustre are for OSTs and I want to be sure that there isn't a different procedure for the MDS since it can only be active/passive.
