Re: High Availability..

... using NFS you need to ensure, that all services accessing files on
the shared mounts rely on the same locking mechanisms - does not sem to
bee a viable path to me. But hav a look at SGI. they portet theire
XFileSystem (XFS) to linux and theres a cXFS (cluster XFS) version

did not yet try it myself, but SGIs IRIX is famous for (c)XFS.

don't try to mount one RAID partitition on more than one host
concurrently - only one can keep state of one filesystem.
