Re: Expanding a Volume Definition with MetaSAN

Apparently, this question didn't have much traction with this community! That's okay, because I found the answer - I thought I'd post it for the next poor soul with this question. My SAN consultant is an XSAN guru, and as MetaSAN does things a little differently, it wasn't clear if I should look to the SAN software for grouping LUNs into a volume, or at Apple's tools.

The solution was to remove the two volumes (created after adding a second RAID set, to fill the XRAID) from the MetaSAN definition, create a RAID 0 ("striped") set comprised of the two RAID5 sets in Disk Utility. Pretty simple, actually. While it did wipe the first set (it's okay, double-backed up!), creating the new, combined RAID definition only took a few seconds.

Performance is now excellent (160mb/sec for one client)! Now to copy back allll the data...

PS: MetaSAN/LAN has been great, it's cheaper and very flexible (as well as cross-platform). Highly recommended, but DO hire a SAN consultant - I wish I had from the start.
