I've got two non-production vfiler units in an HA configuration and I'm trying to redo the disk configurations. On the second unit there's a single aggregate using all of the available disks so I have been unable to move the root volume to a new aggregate. I've tried changing it from raid-dp to raid4, but it fails because there's 11 disks and that's more than the max supported for raid 4. From what I've been reading, it sounds like it should be possible to maybe do a snapmirror/takeover to move the root volume off the aggregate, so I'm looking for guidance or see what other options there are. The mirror option is greyed out on the aggregates page, so not sure if it's not licensed or something else is missing.
