Hi,

You need STONITH. I use IPMI for this purpose. STONITH will power down node that have problems this will ensure that only one node can access the file system.
And you may consider active - passive configuration for heartbeat.

Best regards,

Dear heartbeat users,

I would like to know what is the best way (if any) to avoid a heartbeat cluster using a SAN to be in a situation where the SAN partitions can be mounted on both nodes ... which of courses mean a filesystem corruption
(when using ext3 for example).

Thanks for any help/advice :)
