You can't add/remove devices in a pre-existing vdev. You'll need to either: 1) Backup pool (you can zfs send to an eSATA pool temporarily as a backup) 2) Destroy pool 3) Recreate pool 4) Restore pool One should always have a backup/restore solution or one shouldn't care if they loose their data, there are no ways around this rule. -Ross _______________________________________________ storage-discuss mailing list storage-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/storage-discuss
