Partition Layout

Is there any way to change the partition layout of a hardware appliance?

/opt is usually filled to 90% or more
/opt/mwg/cache is usually filled less than 5% or less


The alternate scheme ( doesn't make sense in our environment as it just changes the ratio from 700GB:40GB to 40GB:700GB.

Re: Partition Layout


Hope you are doing well.

One way is the one which you are aware and is mentioned in below link:-


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



Please refer below link for MWG release notes:-



Also please refer below link for more information on OPT partition:-


Look for Common causes, Preventative measures, and file locations  part in above link.
