I just upgraded from 7.2 to 8.0.
Under 7.2 the pool was like :
NAME STATE READ WRITE CKSUM
tank ONLINE 0 0 0
raidz1 ONLINE 0 0 0
ad6p1 ONLINE 0 0 0
ad10p1 ONLINE 0 0 0
ad8p1 ONLINE 0 0 0
ad4p1 ONLINE 0 0 0
I'd like to use gpt labels or gptids reimporting the pool.
# ls /dev/gpt
disk1 disk2 disk3 disk4
# ls /dev/gptid

ffb4e96a-d497-11de-96bd-001d923bc7a0
I did # zpool import -d /dev/gpt tank
and I got
tank ONLINE
raidz1 ONLINE
ada1p1 ONLINE
ada3p1 ONLINE
ada2p1 ONLINE
gpt/disk4 ONLINE
Now, how to force zpool import to only use gpt labels (or uuids) ? Or
at
least get back to coherent situation ( zpool export tank / zpool import
gives the same now. and zpool import -d /dev, as zpool import -d
/dev/gptid
gives nothing ) ?
Use 'zpool replace' to change the zfs pool to use the gpt names:
zpool replace tank ada1p1 gpt/disk1
zpool replace tank ada2p1 gpt/disk2
zpool replace tank ada3p1 gpt/disk3
NOTE: make sure you use the correct gpt names for each partition, as
the above assumes that ada1p1 is labeled as disk1.

Mmmh, zpool replace will resilver the drive, won't it ?
Yes, it will resilver the drive, but it shouldn't take as long as it
will recognize that it is the same drive. Just wait for the resilver
process to finish before changing the next drive.
Moreover, I can't use replace as when adaXp1 is used, the corresponding
/dev/gpt entry disapears. Unless you mean that I can use replace before
import ?
There was a discussion about this back in July:
http://lists.freebsd.org/pipermail/freebsd-current/2009-July/009440.html
In that discussion, they had used glabel to label each drive, and then
use zpool replace on the active pool to change it to use the label.
Just make sure that you use the gpt name that you assigned to ada1p1,
when replacing it.
Scot
That does not work or there's something I'm doing wrong.

As I said, the label is not present in /dev/gpt while used with adaXp1 (
here ada1p1 has label HD753LJ-1) :
# ls /dev/gpt
HD753LJ-4 zfs-boot
# zpool replace tank ada1p1 gpt/HD753LJ-1
cannot open 'gpt/HD753LJ-1': no such GEOM provider
If I offline the drive first, I get another error :
# zpool offline tank ada1p1
# zpool replace tank ada1p1 gpt/HD753LJ-1
invalid vdev specification
use '-f' to override the following errors:
/dev/gpt/HD753LJ-1 is part of active pool 'tank'
# zpool replace -f tank ada1p1 gpt/HD753LJ-1
invalid vdev specification
the following errors must be manually repaired:
/dev/gpt/HD753LJ-1 is part of active pool 'tank'
I know there is the solution of cleaning the disk and resilvering, but
if I could avoid this ?
