Problem itself happened on FreeBSD, but as I understand it's ZFS related, not
FreeBSD.
So:
I got error when tried to migrate zfs disk between 2 different servers. After
exporting on first, import on second one are failing with following:
Output from import pool:
#zpool import storage750
cannot import 'storage750': one or more devices is currently unavailable
Output from simple import:
#zpool import
pool: storage750
id: 1304450798920256547
state: UNAVAIL
status: One or more devices are missing from the system.
action: The pool cannot be imported. Attach the missing
devices and try again.
see: http://www.sun.com/msg/ZFS-8000-6X
config:
storage750 UNAVAIL missing device
ad6 ONLINE
As I understand, it's because first server have different controler, so disk is
named da2 not ad6, as in second server.
Output from zdb:
#zdb -l /dev/ad6

Are there any way how to learn ZFS that drive name has changed?
