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
It depends - are you using a combined MGS/MDS?
If so, you will have to update the mgsnid on all servers to reflect the
failover node,
plus change the client mount string to show the failover node.
otherwise, it's the same procedure as with an OST.

Apologies, I should have been more descriptive.
I am running a dedicated MGS node and MGT device. The MDT is a
standalone RAID-10 shared via SAS between two nodes, one being the
current MDS and the second being the planned secondary MDS. Heartbeat
and stonith w/ ipmi control is currently
Then it should be the same as the OST case. The only difference between the
two
is that we never allow two active MDSs on the same filesystem, so MDT is
always active/passive.
