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.

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) Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite) Command (m for help): n Command action e extended p primary partition (1-4) p Partition number (1-4): 1 First cylinder (1-39162, default 1): Using default value 1 Last cylinder or +size or +sizeM or +sizeK (1-39162, default 39162): Using default value 39162 Command (m for help): t Selected partition 1 Hex code (type L to list codes): 83 Command (m for help): w The partition table has been altered!

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.
