[Linux-cluster] Advice on Storage Hardware

[Michael Will]

In our case there would be a serial and an ethernet heartbeat between 
the systems.

If one system detects the lack of responsiveness of the other system, it 
shuts it down,
does an IP takeover and mounts the partition that belonged to the other 
system and
now offers it under the new IP address. When the other system has been 
brought up
again, and has been considered stable, it is being advised to take back 
it's ressource,
which does initiate the other system to release it and once that has 
been confirmed, it
takes over the IP address and starts it's nfs service for that partition 
again.

I have only configured this for active/passive setups with a single 
partition so far, but
to extend that to two partitions and an active/active setup should not 
be too hard.
