Description
Citrix ADM, formerly NetScaler MAS
The article describes how to attach an additional disk to NetScaler MAS 12.0 and lower versions.
Points to Note
- You can only add one additional disk to NetScaler MAS apart from the default 120 GB disk. Adding more than one additional disk is not supported.
- The maximum size of the additional disk should not be greater than 2 TB.
Instructions
Complete the following steps to attach an additional disk to NetScaler MAS:
-
Shut down the NetScaler MAS virtual machine.
-
In the hypervisor, attach an additional disk of the required disk size to NetScaler MAS virtual machine.
For example, for a NetScaler MAS virtual machine of 120 GB, if you want to increase its disk space to 200 GB, you then need to attach a disk space of 200 GB instead of 80 GB. Newly attached 200 GB of disk space will be used to store the database data, NetScaler MAS log files. The existing 120 GB disk space will be used to store core files, operating system log files, and so on. The new disk does not have to be formatted. While adding the disk, please make sure we add it under the Primary controller (IDE Controller 0). Do not create a new Controller for adding the disk.
Note: For best performance use fast HDD or SSD. -
Start the NetScaler MAS virtual machine.
-
The NetScaler MAS console will stop on "Define disk configuration". This should be left blank. Do NOT enter anything there, just wait for it to continue.
-
NetScaler MAS will mount the new disk as /var/mps.
-
MAS will rename the old /var/mps folder to /var/mps_archive and copy the contents to the new drive.

Should you choose to remove the new disk from NetScaler MAS VM, the /var/mps_archive directory will be renamed to /var/mps, so that the system can be in the state as it was before the new disk was attached. Otherwise, /var/mps_archive will be not used and can be deleted if needed. The folder will be recreated during next boot but will not contain any files.
