Unable to resize a Netapp volume?

There maybe times that you will need or want to re-size a Netapp volume and normally this is process is very easy to do. You can re-size a Netapp volume using  the ONcommand tool, Filerview, or even SSH into the filer directly. Either of these ways is perfectly fine, no wrong way to do it except for when it fails.

A common error I have seen for failed volume re-sizing is due to the “fs_size_fixed”  error.

The “fs_size_fixed” is a parameter that has been enabled on the volume either during setup or during a snapmirror relationship break. The parameter is there to prevent any type of accidental re-sizing on the volume.  The only way to re-size the volume is to remove the “fs_size_fixed” parameter by connecting directly to filer through an SSH tool and running the following commands. Once the parameter is removed you will be able to re-size the volume.

1. Connect to the filer ( you can use Putty if you have it)
2. First verify that “fs_size_fixed” is enabled on the vol, type : vol status [name of vol]

you will see in the status that “fs_size_fixed” is set to ON

vol1

3.  At the prompt type  : vol options [name of vol] fs_size_fixed off

4. You can confirm that the parameter has been disabled by typing : vol status [name of vol]
