Pity the price of a JBOD is so close to a Controller unit...

The T2000 saw the disks straight away and is "working" for the last 1 hour. I'll be running some benchmarks on it. I'll probably have a week with it until our vendor comes around and steals it from me. > I'm not sure that it had anything to do with the raid controller being > present or not.

I had bits of problems with using my controller 3510 as JBOD as well. Essentially, the disks seems to go away and come back especially when the system reboots. The problem is cleared only when I replaced the controller circuit with the JBOD circuit. That said, I had another 3510 JBOD that has been running very well for over 6 months now. -- Just me, Wire ... _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
