Hi,
Hope you are doing well.
One way is the one which you are aware and is mentioned in below link:-
https://community.mcafee.com/t5/Documents/Web-Gateway-Resizing-the-partitions/ta-p/554184
Second way is also mentioned below:-
/opt partition enlargement:-
The default size of the /opt partition on a Web Gateway appliance can be enlarged, which might prove useful when it comes to storing, for example, large temp files created during downloads.
A new option of the volume scheme wizard allows you to enlarge the partition to a default size of up to 100 GiB. The wizard is started using the mwg -cache -wizard command.
The enlargement can be configured on the appliances as follows:
- Model B appliances
- Model D appliances (except for 4500-D)
- G9 blades
- VMware and HyperV with disk sizes greater than 200 GiB
