Search the NOW site for "Converting a traditional root volume to a flexible root volume" It has the exact steps you need. Requires a reboot.

Hi Tim,

I personally created a new traditional root volume within the aggregate and did an ndmpcopy of the current traditional root volume to the newly created flexible root volume.

I was then able to re-size the new flexible root volume and re-allocate the 'now spare' disks to my aggregate.

Using 2x72GB disks for a traditional root volume on a filer running ONTAP 7 didn't seem right but that's just a personal view. If you can afford the luxury of using 2 disks for your root volume then it's really a matter of choice.

Note my environment was a cluster of FAS940's.

See below for a view pointers on how I migrated my traditional root volume.

Create new root flexible volume - vol create newrootvol aggr0 68G

Verify the new root volume - vol options vol0

Rename the original root volume to another name. - vol rename vol0 vol0orig

Rename the new flexible volume to vol0 - vol rename newrootvol vol0

Make the new flexible volume the new root volume - vol options vol0 root

Enable ndmp - options ndmpd.enable on

Copy original root volume data to new root volume - ndmpcopy /vol/vol0orig /vol/vol0 - Note if the new flexible root volume 'vol0' hasn't been set as root ( see 'vol options' ) you must use the -f flag with ndmpcopy to overwrite the etc directory. See man ndmpcopy.

Destroy the original root volume - vol offline vol0orig - vol destroy vol0orig - disk zero spares

( Make sure you're happy everything is in order before you do this ) Note, I'd snapmirrored my traditional root volume to a remote filer to ensure I'd a backup in the event of any problems. You can never be too careful...

Resize new flexible vol0 - vol size vol0 10G

Regards, Philip
