I think that depends on what exactly you mean by cluster. Some HW RAID
cards support a 'clustered' mode that is different from what we think of
as a beowulf cluster. Their version of 'cluster' is two raid cards
attached to the same set of disks. If one raid card/machine goes away,
the other can take over. This is not something software raid for linux
Now, if you're talking about a software raid filesystem, and sharing out
to a cluster using nfs/samba/etc, then it works fine.
