How to migrate root volume to new volume in netapp

Procedure

Currently disks cannot be directly removed from any traditional volume or aggregate, a new root volume must be created then the data can be migrated. If there are enough spare disks available to create a new root volume

1. Create a new volume ("root") with 2 disks:
   filer> vol create root 2
2. Verify that the volume settings of vol0 and root are the same:
   filer> vol status -v
3. Verify that NDMPD is enabled:
   filer> options ndmpd.enable
4. Copy the contents of vol0 to root:
   filer> ndmpcopy /vol/vol0/etc /vol/root/etc
5. Make the "root" volume the root volume with the following command:
   filer> vol options root root
6. Verify that the used space of root is the same as vol0
   filer> df

To change the C$ share to map to the new root volume:

1. Determine which shares have a vol0 path:
   filer> cifs shares
2. filer> cifs shares -delete  C$
3. filer> cifs shares -add C$ /vol/root
4. filer> cifs access C$ BUILTIN\Administrators Full Control
5. filer> cifs access -delete C$ everyone

Eventually add more groups to this share. Do the same for any other shares with the path vol0.

To reboot filer and destroy the volume, follow these steps:

1. Verify that the new volume root is shared:
   filer> cifs shares
2. Make the necessary changes in the /etc/exports file to ensure the path to the root volume eventually exported is mountable from a UNIX machine
3. Reboot the filer
   filer> reboot
4. Verify that vol0 is marked offline
   filer> vol offline vol0
5. Destroy the volume
   filer> vol destroy vol0
