Moving volumes

About moving volumes  Top

You can move volumes from one filer to another. You might want to move a volume to a different filer to perform one of the following tasks:

You can physically move disks, disk shelves, or loops to move a volume from one filer to another. You need the manual for your disk shelf to move a volume.

The following terms are used:

Moving a volume  Top

To move a volume, complete the following steps.

Step

Action

1

Enter the following command at the source filer to locate the disks that contain the volume:

vol status vol_name -r
Result

The locations of the data and parity disks in the volume appear under the volume name on the same line as the labels Data and Parity.

2

Follow the instructions in the disk shelf hardware guide to remove the disks, from the source filer.

3

Halt and turn off the destination filer.

4

Install the disks in a disk shelf connected to the destination filer.

5

Turn on and boot the destination filer.

Result

When the destination filer boots, it places the foreign volume off-line. If the foreign volume has the same name as an existing volume on the filer, the filer renames it volume_name(1), where volume_name is the original name of the volume.

Caution
If the foreign volume is incomplete, repeat Steps 1 and 2 to add the missing disks. Do not try to add missing disks while on-line--doing so causes them to become hot spare disks.

6

If the filer renamed the foreign volume because of a name conflict, enter the following command to rename the volume:

vol rename vol-name new-name

vol-name is the name of the volume you want to rename.

new-name is the new name of the volume.

Example

The following command renames the users(1) volume to newusers:

vol rename users(1) newusers
7

Enter the following command to bring the volume on-line in the new filer:

vol online vol-name 

vol-name is the name of the volume.

Result:

The following events occur:

  • The volume is on-line in its new location.
  • Entries in the /etc/exports file and shares that refer to the volume become incorrect.
  • The in-memory information about active exports gets updated automatically, and clients continue to access the exports without problems.
8

Enter the following command to confirm that the added volume came on-line:

vol status vol-name 

vol-name is the name of the volume.

9

If you have...

Then...

An NFS-only filer

Go to Step 11.

A CIFS-only or multiprotocol filer

Create shares that refer to the new volume to enable clients to access it, then go to Step 10.

10

If you have...

Then...

A CIFS-only filer

You are done.

A multiprotocol filer

Go to Step 11.

11

Update the system /etc/exports file with the new volume.

12

Run exportfs.

13

Add the appropriate mount point information to the /etc/fstab or /etc/vfstab file on clients that mount volumes from the filer.
