My Ubuntu 12.04 system has two zpools: rpool (containing the root filesystem) and rdata (containing all other data). rdata was originally 2 x 1TB disks mirrored.
Because I couldn't upgrade rdata to 3TB disks (wrong ashift) I had to create a new zpool from the new 3TB disks: initially called datapool. I then rsync'd all the data across, exported rdata, imported datapool as rdata and Bob's your Uncle. I then powered off and removed the old disks. However...
When I powered back on, zpool status shows
pool: rdata
state: UNAVAIL
status: One or more devices could not be used because the label is missing
or invalid. There are insufficient replicas for the pool to continue
functioning.
action: Destroy and re-create the pool from
a backup source.
see: http://zfsonlinux.org/msg/ZFS-8000-5E
scan: none requested
config:

As you can see, zpool status is still showing the old rdata; which is not available.
zpool import shows
pool: rdata
id: 7033445233439275442
state: ONLINE
action: The pool can be imported using its name or numeric identifier.
config:
rdata ONLINE
mirror-0 ONLINE
scsi-SATA_ST3000DM001-1CH_W1F1EE1G ONLINE
scsi-SATA_ST3000DM001-1CH_W1F25SE2 ONLINE
This is the correct rdata
Question: How do I get Ubuntu to forget all about the old zpool?
