not strictly a zfs question but related: after giving a lot of thought to the appropriate zpool layout in an x4500, we decided to use raidz2 5x(7+2)+1 layout, paying attention to having no more than two disks per set in each controller. in the process, i want to move my root mirror to another controller, say C6T0. is there any reason why factory install comes with C5T0 and C5T4? a limitation of the bios or some other reason i am missing? (i may need to RTFM harder... :) thanks oz -- ozan s. yigit | oz at somanetworks.com | o: 416-348-1540 if you want to have your head in the clouds you need to keep your feet on the ground. -- terry pratchett -------------- next part -------------- A non-text attachment was scrubbed...
