Check Point Gaia LVM

Our Check Point Management Server has been migrated into Virtual Edition platform which is running on Citrix Xen server. Originally it is only 100GB hard drive set for testing.

After running stabilised for a couple of days, I decided to enlarge the log space since 50G logging is definitely not enough.

My old 2014 post “Resize Checkpoint Firewall’s Disk/Partition Space (Gaia and Splat Platform)” has some details to enlarge Logical Volume size with existing free space which supposed to be used as snapshots. This post will focus how to add a new disk into your system and enlarge your log logical volume.

Here are all steps related to this task. Those steps also fit into Vmware environment.

300GB virtual disk has been added into our Management server virtual machine.

Disk /dev/hdb doesn't contain a valid partition table

[[email protected]:0]#
fdisk /dev/hdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.


The number of cylinders for this disk is set to 39162.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

During above steps, I created a new virtual group group_john1 and a new logical volume vol2. Unfortunately, those steps are not needed.

On next section, I will show how to remove logical volume vol2 and virtual group one by one.

After deleted that new virtual group, I will extend existing logical volume to this new disk.

Resizing lv_log Logical Volume
==============================
lv_log size can be
between 13G to 355G.
Enter the new size(GB) or leave blank to cancel: 300

Note that all Check Point products will be shutdown during the resizing operation and the machine will be rebooted automatically at the end of the process.
This may take several minutes.
