Lustre discuss - Jan 2010 - What HA Software to use with Lustre

Hi Guys,

I am setting up our new Lustre environment and was wondering what is the
recommended (stable) HA clustering software to use with the MDS and OSS
failover.  Any input would be greatly appreciated.

Thanks,
-J

Hi Jagga,

Linux HA (heartbeat) is known to work quite well with Lustre. Check 
Lustre manual for details. Also, pacemaker is overtaking heartbeat and 
you may not find old rpms. Alternatively, you can download heartbeat 
packages from

Cheers,

The docs describe heartbeat but the software is not recommended any more. 
Neither heartbeat version 1 nor heartbeat version 2. Instead the projects 
openais and pacemaker replaced the funcionallity of heartbeat. For the new 
project please see
www.clusterlabs.org

A introduction into pacemaker can be found at:

I wish I were aware of the "crm" CLI before trying to take the XML way
according the link above:

We are working on a documentation how to set up lustre together with 
pacemaker. As soon as we are finished it will show up in the wiki.
