Re: Cluster aware software RAID?

Hi

The Raid1 resource agent that comes with LinuxHA was
adapted to provide active/passive failover per MD raid device,
so that only one node has an MD active, while the other
nodes in your cluster can activate on failover. MD also now
has disk-based bitmaps so that when a RAID is reactivated on
some (other) node, only what's out of sync will be resynced.

Hth,
Robert

Hello,

I'm a total novice wrt EVMS so pardon naivete of my question:
Does EVMS allow for a clustered RAID storage solution where 
2 disks on a shared bus attached to 2 cluster nodes 
are RAID 1 mirrored? What I'm trying to figure out is whether  
EVMS (private?) container with RAID md can be failed over should 
one of the nodes failed. (For the sake of argument let's say
I can't use DRBD 8-) 

Thanks!
