Several choices. Ask on Linux-HA (heartbeat). (Or search their archives.)
This still does not get you a "local" Win2k drive. Exchange and ms-SQL only install onto local drives.

I've been able to use LVM across HyperSCSI exported disk subsystems. 2
systems exporting thier unpartitioned disks, a third client takes these 2
disks and creates an LVM group and LV that spans both disks. Worked good,
but I didn't have time to stress test it. I was able to get a second client
to access the LVM group and write to it.

What was your setup and how did it fail? No connection? Such bad
performance that it didn't work?

I went that route awhile ago and did manage to get some HA clusters
going. However, the problem is that most solutions require some type of
hardware based shared SCSI device or some type of FC fabric to actually
provide the connectivity. With the newer (read cheaper) ATA RAID
systems, I am not sure how to "share" the physical storage between
multiple systems in a cluster. This is not necessarily a clustering
issue.

Yep... As well as other software we use. :(
I'd appreciate hearing about your test setup for the iSCSI/HyperSCSI.
Thanks in advance,
- Steve

Just to re-iterate, HPs Virtual Replicator does this. (IIRC $10K)
They like you to put a MSA-1000 FC Array behind your VR server (IIRC $15K entry), but it supports/exports any FC array or local disk solution.
It does not provide any RAID aspects.
If you want to know more, e-mail me off-list.

Sistina's GFS will do this as well. We employ it here with good results. GFS can live happily in LV2.
