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?
Martin

Yeh, Sorry I forgot to highlight the versions.

FreeBSD 8.2-STABLE amd64
ZFS filesystem version 5
ZFS storage pool version 28


I don't know what to say except try it with 9.0, if possible. The RC1 
just got out. I'm no expert on this, sorry I can't be more helpful.
