Yesterday I saw the alert, that one disk on our VCSA is running out of space. This article describes how to increase the Disk Space on the VCSA.

First I saw the alert on the VAMI of our vCenter Server.

On the monitor tab you will find on which disk serves the mountpoint. Here it is disk13 for the /storage/archive mount point.

Now login to your vCenter via SSH and start the shell.
Execute the following command to list all partition.

Now change the Size of the Disk via vSphere Client.

Switch back to SSH session and execute the following command

After the script completes execute df -h again.

The VAMI need some time to get the information of the resized disk (about 5 minutes).

The Monitor tab also reports the correct values after some minutes
