In order to provide more disk space on the iDNA appliance, the underlying disk, partition and logical volume all have to be extended.
| Note |
|---|
Please note that all virtual disks should be located on the same physical storage for best performance. In contrast to the old CentOS appliance, it is now recommended to enlarge the existing VMWare disk, rather than adding new virtual disks. |
...
The easiest way to enlarge a partition in the appliance is to use the installed partition manager GParted. Please launch it using the Applications or Activity menu (or using the shell command "gparted").
After starting GParted, you may be prompted with a message about whether the GPT partition should be resized to use all available space. Please confirm this change by clicking "Fix"!
- Right-click the partition that needs to be extended and click on Resize/Move
- Draw the right border to the end, so that all fee space is taken up by the resized partition and click Resize
- Confirm and apply the changes by clicking the green check-mark (Apply All Operations) in the tool bar
Creating a Partition on a New Disk in the Appliance
...
- Select the new physical disk:
- Select the unallocated space, open the Device menu and on click on Create Partition Table:
- Click on Select "gpt" as partition type and click on Apply in the warning:
- Select the new unallocated space, right-click and select New:
- From the Createas drop down menu, select PrimaryPartition and chose lvm2pv as File system (if needed, a Label can be defined):
Save your changes by clicking the apply button - also on the popup message
Info The new disk is now available to the operating system, but still needs to be made available to logical volumes.
- Start the "LVM Manager" (Logical Volumes Manager) from the Applications/Activities menu and select the original disk "sda" on the left hand navigation bar,
right-click "cl-pan" in the device list, select "Edit" and click "Modify parents"
- Click "Add a parent" and select your new disk in the list of available devices and click OK.
- Apply the changes using the check-mark symbol (Apply pending actions) in the top tool bar
You can leave the LVM Manager application open, as we will need it during the next steps.
Adding the new Disk Space to Logical Volume Groups
...
- Start a "Terminal" from the Applications/Activities menu, execute the command "ifa stop" and wait for the command to finish (this may take several minutes).
- Start the "LVM Manager" (Logical Volumes Manager) from the Applications/Activities menu and select the volume group "cl-pan" on the left hand navigation bar.
- Select the "pgdata" volume, right-click it and execute "Unmount"
- The unmount process will reset the selection in the device list, so please select "pgadata" again.
Tip: volumes can also be selected via the top navigation bar:
- Right-click "pgdata", go to the edit sub-menu and select "Resize"
- Drag the indicator to the right to add disk space to this volume and confirm with "Resize"
Note: even though were are adding all disk space to one volume in this example. The , the new available disk space may be divided between multiple volumes. For more information on calculating disk space requirements, please refer to the Setup Guide. - Apply the changes using the check-mark symbol (Apply pending actions) in the top tool bar
- After confirming the queue, you should see a success message like the one below and the new disk space will now be available to iDNA.
- To complete the changes, we need to start iDNA Applications again. Since one or more partitions might be unmounted at this point, the easiest way to do this is execute the command "reboot" in the command line.
