Hello.
Several maintenance of a ZFS pools has to be done and my intention was
to swap the 2TB hd disk (WDC WD20EARS-00MVWB0) with a 3TB hd disk
(WD30EZRX).
zfs umount works well,
zpool export POOL also worked well,
but I didn't find any "detach command" within camcontrol (I use the new
AHACI/CAM layout in the kernel on FreeBSD 9.0-CURRENT/amd64 r223597, so
my harddrives all show up as ada0 to ada4.
Since the box has a IcyDock 5-Slot backplane attached to the ICH0R
chipset and camcontrol doesn't reveal any detach command like atacontrol
did, I trusted in hotplugging capabilities and simply pulled the disk.
All right, the box reported a lost device but did not crash. The I
inserted the new drive. Entered
camcontrol rescan all
and
camcontrol devlist showed up the new device. But I can't do anything
with the drive. Even with the former device inserted again, rescaned
etc., a zpool import command get stuck as well as any diskinfo -ctv ada4
issued to the device. The drive shows up in camcontrol devlist, but
seems inoperable. What I'm doing wrong?
Oliver
