CHECK POINT BIG STORAGE – HOW TO ADD SPACE TO YOUR SERVER.
May 31, 2016 | Filed Under: Check PointFirewall
The ext3 filesystem which Check Point software runs, based upon RHEL, only supports 2TB as a maximum file size for booting. So, we need to add in our additional storage after the OS is installed, up to 16TB.
Source: https://access.redhat.com/solutions/1532
Let’s go through it. We will base our starting point on a few assumptions.
- First, you have added the physical drives into your server.
- Second, you have added the drives to the array and raid configuration of your choice.
- Third, you have a working installation of Gaia.
STARTING POINT
We are going to increase the size of our log partition.
