Mirror pool drives keep reverting to HFS
Posted: Sat Aug 04, 2018 9:30 am
So, this has happened twice now: I create a mirror pool, export it, shut down the external dual disk enclosure, restart the external dual disk enclosure... and the HFS disks come back and show up on the desktop (and, obviously, I can't import the pool any longer). Here is the annotated terminal session, it's very simple:
Details: running 1.7.2 zfs under El Capitan 10.11.6, up to date with all security patches. Other World Computing dual disk Elite enclosure set up as JBOD. Two 4 TB disks. Connected via the ESATA interface. Any suggestions on what I'm doing wrong?
- Code: Select all
sh-3.2# zpool import ELITE
cannot import 'ELITE': no such pool available
<I see two HFS volumes on the desktop, so I eject them and create a new pool with the command below>
sh-3.2# zpool create -f -o ashift=12 -O casesensitivity=insensitive -O normalization=formD ELITE mirror disk11s2 disk10s2
sh-3.2# zpool export ELITE
Running process: '/usr/sbin/diskutil' 'unmount' '/Volumes/ELITE'
Unmount successful for /Volumes/ELITE
sh-3.2#
<I power off the external enclosure>
<I power on the external enclosure>
<the two HFS disks show up again>
