Extending the CTERA Main Database or Catalog Node Storage Pool
Note: CTERA recommends changing the storage with the help of CTERA Support (http://www.ctera.com/support).
To extend the CTERA main database or catalog node storage pool:
1 For each CTERA Portal instance you have installed, stop CTERA services, by doing the following:
a Open an SSH session to the CTERA Portal instance.
b Log in as root user.
c Run the command to stop the CTERA Portal services: ctera-portal-manage.sh stop
2 Attach a VMDK drive to the CTERA Portal server, by doing the following:
a In the vSphere Web Client, right-click the CTERA Portal virtual machine and click Edit Settings.
The virtual machine settings are displayed.
b In the Virtual Hardware tab, click select New Hard Disk for New Device and click Add.
A new hard disk is added to the settings.
c Specify the disk size you want for the new disk.
d Click OK.
The new VMDK hard disk is added.
Note: In certain cases, you may be required to reboot the CTERA Portal server in order for the new VMDK drive to be identified.
3 Extend the CTERA Portal storage pool, by doing the following:
a Log in as root user to your CTERA Portal server over SSH.
b Run the following command to identify the name of the device you attached: fdisk –l
Locate the device name according to its size and usage information.
c Run the following command to stop the portal services: ctera-portal-manage.sh stop
d Run the command to extend the CTERA Storage Pool: ctera-storage-util.sh extend_storage deviceName
Where deviceName is the device name copied in the previous step.
The main database or catalog node storage pool is extended.
4 To view the storage pool size, run the following command: df –h /usr/local/lib/ctera
5 For each CTERA Portal instance you installed, starting from the CTERA Portal main database and catalog node and proceeding to the application servers, start CTERA Portal services.
a Log in as root user to each CTERA Portal server over SSH.
b Run the following command to start the portal services: ctera-portal-manage.sh start
