I don't expect miracles from ZFS if hardware is not compatible. However, I did expect for ahd driver and Adaptec U320 to still be fairly common and well aged, thus being compatible, but perhaps that isn't the case. Is there a list of compatible controllers? I do not understand how formatting a drive using UFS would solve my issues. I pulled 2 drives out from functional zraid2 to simulate drive failure and the system froze. Clearly there is an issue using this controller with ZFS in ZRAID setup. It shouldn't matter what I have installed on a drive. When a drive is pulled out of hot-plug enclosure, it should get marked as offline. -Simon On Wed, 2 May 2012 09:50:41 -0700, Freddie Cash wrote: >On Wed, May 2, 2012 at 9:46 AM, Simon <simon@optinet.com> wrote: >> Am I the only one using this SCSI card and ZFS? does anyone use any type of >> Adaptec U320 SCSI card?
