Increasing disk space on VCSA

Over time your VCSA will run out of disk space and you will need to increase the disk space. I will describe how I have performed this on one of my PSC as I was alerted by my monitoring system. My environment is vSphere 6.0 U2.

• Log on to your PSC controller using the root account. 
• Run "Shell.set" 
• Run "shell "
• Run the command "df -h" and you should get an output like the one below. 

You can see that I have ran out of disk space on mount point "/storage/log". At this point I would go to the VM in web client to increase the relevant disk but when you look at the disks attached to the VM (11 in total) I can't tell which disk has the mount point of "/storage/log". After searching on VMware KB site I found an article which list which mount point resides on which disk

So now you can see "/storage/log" is using "vmdk5" so now I can go and modify the disk size of "vmdk5"

• Hop back to the SSH session you have to the PSC, run the following command "cd /usr/lib/applmgmt/support/scripts/"
• Now run command to increase the disk space "./lvm_cfg.sh storage lvm autogrow" and if you are successful you will see a message "Command executed successfully"
• Run df -h and now you should see the mount point "storage/log" space increased 

Here is the official article from VMware KB2126276
