Anyone have any experience using a big RAID unit over iSCSI with Mac OS X Server? I have a Promise unit 16TB but its only been in service for a couple of months, not very heavy use but the filesystem seems to have been corrupted. I get the "Cannot repair, please copy everything off and format" message. This is supposed to be an enterprise class RAID unit, I shouldn't have to rebuild it every few months. Is there something special I should be doing? Using the ATTO iSCSI initiator and the volume is a single HFS+ volume.
