Sorry, I meant to say zpool offline. After I take the drive out marked as offline, and put it back in, the system spits the following: ahd0: someone reset channel A ahd0: WARNING no command for scb 242 (cmdcmplt) QOUTPOS = 283 >>>>>>>>>>>>>>>>>>>Dumpt Card State Begins>>>>>>>>>>>> ahd0: dumping card state.... followed by a lard amount of data. It then freezes and won't executed any new commands. beta_srv# uname -a FreeBSD beta_srv 9.0-RELEASE FreeBSD 9.0-RELEASE #0: Tue Jan 3 07:15:25 UTC 2012 root@obrian.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC i386 beta_srv# dmesg | grep ses ses0 at ahd0 bus 0 scbus0 target 6 lun 0 ses0: <SUPER GEM318 0> Fixed Processor SCSI-2 device ses0: 3.300MB/s transfers ses0: SAF-TE Compliant Device Thanks, Simon On Tue, 1 May 2012 14:26:35 -0700, Freddie Cash wrote: >On Tue, May 1, 2012 at 1:57 PM, Simon <simon@optinet.com> wrote: >> I decided to give ZFS ZRAID2 a shot after getting fed up with some legacy >> hardware RAID cards that don't properly perform, or at all, patrol-reads + >> consistency checking.
