To avoid the need for a shared disk I had thought we could integrate in DRBD,  which does network-based disk mirroring so we can have HA without a shared disk.  To my knowledge, no one has tried the integration yet.

Subject: RE: [SSI-users] Shared disk

Basically, what we'd like to have is a clustering setup with no shared disks, and failover capability . . . Can openSSI provide that??

What we're trying to do is set up a clustered sendmail environment  --  has anyone done that??  Trying to keep the hardware at a minimum, so we want to avoid a front-end balancer, or a back-end shared disk.

Thanks again!

You need shared disks if and only if you need a failover cluster.

You really don't have to do anything special to work without one. At
least, I never do.
