Increasing Storage for a VMware Linux Backup Gateway

To increase storage for a VMware Linux backup gateway, instead of extending the machine's existing VM disks (VMDKs), add more VMDKs—in even numbers (2, 6, 20, and so on).

Procedure

In VMware, do the following:
1. Add the new disks.
  
  For instructions, see Add a New Hard Disk to a VMware Virtual Machine in the VMware documentation.
2. List all block devices in the system by running the following command:
```
lsblk \-l
```
  The new VMDKs are at the end of the list.
From the Linux OS of the backup gateway, do the following:
1. Stop all Commvault Cloud services by running the following command:
```
commvault -all stop
```
  You might need to reboot your system to complete this operation.
2. To increase the space for the IndexCache, JobResults, Installation Directory, and Logs folders, add the VMDKs to the vg_metallic volume group by running the following commands:
```
pvcreate /dev/sdd
```
```
vgextend vg_metallic /dev/sdd
```
```
opt/metallic/Base/commvault stop
```
```
lvextend -r -l "15%VG" -q "vg_metallic/lv1"
```
```
lvextend -r -l "5%VG" -q "vg_metallic/lv2"
```
```
lvextend -r -l "25%VG" -q "vg_metallic/lv3"
```
```
lvextend -r -l "55%VG" -q "vg_metallic/lv4"
```
```
/opt/metallic/Base/commvault start
```
3. To increase the space for the deduplication data disk (DDB), add the DDB to the vg_metallic_2 volume group by running the following commands:
```
pvcreate /dev/sde
```
```
vgextend vg_metallic_2 /dev/sde
```
```
/opt/metallic/Base/commvault stop
```
```
lvextend -r -l "90%VG" -q "vg_metallic_2/lv_ddb"
```
```
/opt/metallic/Base/commvault start
```
4. Start all Commvault Cloud services by running the following command:
```
commvault -all start
```
To verify the status of the VMDKs, in Commvault Cloud, do the following:
1. Go to Manage > MediaAgents.
2. In the row for the backup gateway, click the action button , and then select Check readiness.
