Command "zpool online -e" doesn't work

[bitloggerig]

I'm trying to expand raidz zpool after replacing a drive with a bigger one:

# zpool status storage
  pool: storage
 state: ONLINE
 scan: scrub repaired 0 in 6h43m with 0 errors on Sat Jun  9 09:56:23 2012
config:

        NAME                                 STATE     READ WRITE CKSUM

errors: No known data errors

Thanks, this one looks pretty straight forward. ZFS is simply not creating the needed partition tables on the new device. It simply assumes the device already has one and attempts to expand it. See zpool_do_online->zpool_vdev_online()->zpool_relabel_disk(). If you were to manually create the devices partition table with something like parted you should be able to avoid this issue for now.

This is probably a duplicate of #808. Or rather, #808 is a duplicate of this one, sorry about that.

Closing as a duplicate of #808 which has been fixed.
