Extending disk space on BIG-IP VE

Hi, 

Consider extending /var directory , because it can cause much unexpected issues if there is no free space on /var. 

for example by default your ucs backup files are saved in /var also it's rotating files before doing Upgrade. 
I saw with one of our customer his units lost it's mgmt connectivity due to /var is full , also sometimes it caused the configuration to fail to load after upgrade due to un-sufficient space in /var.

in general >>> Consider increasing your resource in the first time of creating your VEs. 

I see that 10 GB is good for /var >> this is the most important directory to be modified in space.

For other directories set whatever you want and suitable for existing resources in your hypervisor.
