[zfs-discuss] Using ZFS iscsi disk as ZFS disk
Is there any reason why an iscsi disk could not be used to extend an rpool? It would be pretty amazing if it could but I thought I'd try it anyway :-) The 20GB disk I am using to try ZFS booting on SPARC ran out of space doing an image update to snv122, so I thought I'd try extending it with an iscsi disk on the data pool (same machine, different disks). After formatting the disk with an SMI label, trying to add the new disk results in # zpool add rpool c4t600144F04AA7AA68d0 cannot label 'c4t600144F04AA7AA68d0': EFI labeled devices are not supported on root pools. # Should it be possible to do this (SPARC snv103), and if so, how to make it work? Use a different iscsi host maybe? Perhaps I should have used a plain file, or could it be impossible? Maybe I should split the UFS boot mirror and try this on one of those disks instead :-( Separately, I have succeeded in using an iscsi disk (same hardware) as a ZFS disk in an AMD64 Virtualbox, so it is possible, although /var/adm/messages is full of messages like this: Corrupt label; wrong magic number even though the disk works just fine in the VM. Any hints much appreciated Thanks -- Frank ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

It obviously doesn't have an SMI label on it given that error message. However that still isn't your real problem. The root pool (ie the one you boot from) can only be a mirror that means that regardless of iSCSI or EFI label that 'zpool add' was going to fail anyway like this: # zpool add rpool c4t600144F04AA7AA68d0 invalid vdev specification use '-f' to override the following errors: mismatched replication level: pool uses mirror and new vdev is disk -- Darren J Moffat ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
