Untouchable drives from GUI

first my background. running 9.2.0.1
following ZFS layout:

Code: Select all

nas4free:  # zpool status
  pool: tank1
 state: ONLINE
status: The pool is formatted using a legacy on-disk format.  The pool can
        still be used, but some features are unavailable.
action: Upgrade the pool using 'zpool upgrade'.  Once this is done, the
        pool will no longer be accessible on software that does not support feature
        flags.

My goal is to eventually replace both drives that make up mirror-0. They're 640GB and I want to replace with 2TB ones. My thought was to do a replace. Pull one drive and replace with one of the bigger ones. wait for the resilver to finish, replace the other one, wait for that to finish and then go into the cli and tell zfs to expand both drives. When I go into the GUI (Disks>ZFS>Pools>Tools) and select replace as the option, I only see the 2 mirror-1 drives, not the mirror-0 drives at all. Can't remove them from the GUI either. The history for the pool isn't remarkable but I'll include it. Any idea why the first mirror seems to be "untouchable" from the GUI?

Code: Select all

History for 'tank1':
2011-03-30.21:53:27 zpool create tank1 mirror /dev/gpt/ad6 /dev/gpt/ad8
2011-03-30.21:58:03 zfs create -o compress=off -o exec=off tank1/users
2012-09-15.14:13:14 zpool import -d /dev -a
2012-09-16.06:31:58 zpool import -d /dev -a
2012-09-16.06:34:26 zpool upgrade tank1
2012-09-16.08:12:06 zpool add tank1 mirror ada0 ada1
2014-05-02.19:36:17 zpool import -d /dev -f -a

Not following you on the mirror 1 vs mirror 0.

However what you describe is how I backup. I shutdown, pull a drive, swap in one that was offsite for a month and resilver.

It works for me

The mirror-0 drives never show up on the GUI, only the mirror-1 drives
