Hi,
I have created a raidz2 with disk I labeled with glabel before. Right
after creation this pool looked fine, using devices label/tank[1-6].
I did some tests with replacing/swapping disks and so on. After doing a
zpool offline tank label/tank6
remove disk
camcontrol rescan all
insert disk
camcontrol rescan all
zpool online tank label/tank6
I got the disk back, but not under the requested label, but under the da
device name:
pool: tank
state: ONLINE
scrub: resilver completed after 0h0m with 0 errors on Tue Feb 9 14:56:37

Why does this happen? Is there any way to get zfs to use the label again?
After the device is in use, the label in /dev/label disappears. When
taking the device offline again, the label is there, but cannot be used:
pigpen# zpool offline tank da6
pigpen# zpool status
pool: system

attempt was made to correct the error. Applications are
unaffected. action: Determine if the device needs to be replaced, and
clear the errors using 'zpool clear' or replace the device with 'zpool
replace'. see: http://www.sun.com/msg/ZFS-8000-9P

pigpen# zpool online tank label/tank6
cannot online label/tank6: no such device in pool
In a different thread I found the hint to use zpool replace to get to the
usage of labels, but this seems not possible, either:
pigpen# zpool replace tank label/tank6
invalid vdev specification
use '-f' to override the following errors:
/dev/label/tank6 is part of active pool 'tank'
pigpen# zpool replace -f tank label/tank6
invalid vdev specification
the following errors must be manually repaired:
/dev/label/tank6 is part of active pool 'tank'
pigpen# zpool replace -f tank da6 label/tank6
invalid vdev specification
the following errors must be manually repaired:
/dev/label/tank6 is part of active pool 'tank'
I'm running out of ideas here...
