[zfs-discuss] How to grow root vdevs?
Folks, I am trying to understand if there is a way to increase the capacity of a root-vdev. After reading zpool man pages, the following is what I understand: 1. If you add a new disk by using zpool add, this disk gets added as a new root-vdev. The existing root-vdevs are not changed. 2. You can also add a new disk by using zpool attach on any existing disk of the pool. However, the existing disk cannot be part of a raidz vdev. Also, if the existing disk is part of a mirror, all we are doing is increasing redundancy but not growing the capacity of the vdev. The only option to grow a root-vdev seems to be to use zpool replace and replace an existing disk with a bigger disk. Is my understanding correct? Thank you in advance for your help.

The root device can only be a single drive or a mirror. 2. You can also add a new disk by using zpool attach on any existing disk of the pool.

Don't forget to install grub on the new drive. -- Ian. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
