Had a prblem when I needed to export a zpool and import again. The pool used
glabels for each device but after the import the pool is now using the raw
devices names.
sandbox# zpool create -f tank3 raidz1 /dev/label/012 /dev/label/066 label/040
label/064
sandbox# zpool status
pool: tank3
state: ONLINE
scan: none requested
config:
NAME STATE READ WRITE CKSUM
tank3 ONLINE 0 0 0
raidz1-0 ONLINE 0 0 0
label/012 ONLINE 0 0 0
label/066 ONLINE 0 0 0
label/040 ONLINE 0 0 0
label/064 ONLINE 0 0 0
sandbox# glabel list | grep Name
1. Name: label/012
1. Name: ada0
1. Name: label/066
1. Name: ada1
1. Name: label/040
1. Name: ada2
1. Name: label/064
1. Name: ada3
sandbox# zpool export tank3

The only way I could get zfs to use the glabels without destroying the pool
was to install a new drive, glabel it and then replace that with the first
drive, then do the same for each drive.
sandbox# zpool replace -f tank3 /dev/ada0 label/014
... wait for completion
sandbox# zpool replace -f tank3 /dev/ada1 label/012
... wait for completion
Note that I did not need to glabel any drive (except the newly installed
spare) so the label was still intact on each drive.
So, How do I do an export and import and still keep the glabels that the
original pool was created with.
Hi!
I just tried it and had no problem on 9.0-BETA3 AMD64. The labels were
still intact and used by ZFS after the import. Which FreeBSD version are
you using?
