Mostly, yes. From the HA perspective, Lustre can now be managed just
like any other filesystem, if you are using Heartbeat you can now use
the built-in Filesystem resource.
On the Lustre setup, there are two things that may need to be done:
MDS failover:
When creating the filesystem, a pair of MDS nodes should be specified
with the --mgsnode= parameter. ( And clients must reference both MDS
NIDS when mounting, this is unchanged from 1.4 )
OSS failover:
When creating, specify the failover partner with the --failover= parameter.
These parameters can be changed after filesystem creation with
tunefs.lustre.
Thank you Cliff.
I didn't catch this in the manual -- will look again.
