How to increase the storage space on VMWare for VXG Server

Option #1 - Expand an existing Hard Drive (SCSI)

1. First of all, turn off your Virtual machine with the VXG server if it was launched.

2. You need to expand the Hard Disk in VMWare WorkStation (Example: expand from 10Gb to 15Gb)

It will show a success message:

3. Power on the virtual machine and log in.

4. Check the disk size

CODE

# lsblk

(You can see that /sda changed from 10GB -> 15GB. Now we need to allocate /sda2 )

5. Resize dev/sda2 by parted (partition editor)

CODE

# parted

(parted) p
(parted) resizepart
(parted) 2 (your lvm volume)
(parted) 16.1GB (choose the same size as your Disk /dev/sda:)
(parted) quit

6. Apply these changes at the core level

CODE

# pvresize /dev/sda2

7. Find the PATH of our root lvm volume

CODE

# fdisk -l

8. Resize the root lvm volume

CODE

# lvextend -r -l +100%FREE /dev/mapper/cl-root

9. Check the new size of the lvm volume (cl-root)

CODE

# lsblk

10. Reboot the Virtual Machine

Option #2 - Add a new Hard Drive (SCSI)

This option allows using VXG Server on VMWare with 2 disks, one for storage and one for the system files.

1. First of all, turn off your Virtual machine with the VXG server if it was launched.

2. You need to add a Hard Drive in VMWare WorkStation

3. Turn on this virtual machine and log in.

4. Check your added disk

CODE

# lsblk

5. Install lvm if necessary

CODE

# yum install lvm2

For Ubuntu, Debian type of OS:

CODE

apt-get install lvm2

6. Mark your added PV (/sdb) disk for LVM

CODE

# pvcreate /dev/sdb

PV - Physical Volume

You can check your PV with:

CODE

# pvdisplay

7. Create a VG at your PV (/dev/sdb).

CODE

# vgcreate cl2 /dev/sdb

VG - Volume Group
“cl2” - enter the name of your VG

You can check your VG with:

CODE

# vgdisplay

8. Create an LVM disk with all free disk space from /sdb.

CODE

# lvcreate -l 100%FREE -n storage cl2

“storage” - enter the name of your LVM
“100%FREE” - allocate all free disk space to this new LVM

You can check your LVM with:

CODE

# lvdisplay

9. Create filesystem of your LVM (/dev/cl2/storage)

CODE

# mkfs.xfs /dev/cl2/storage

(you can use xfs or ext4 filesystem for storage)

10. Create a directory for storage mounting

CODE

#mkdir /storage

(from the root directory in our example)

11. Add your LVM to automounting. (edit fstab by vi editor)

CODE

# vi /etc/fstab

press “i” to start editing the file and add a string:

/dev/mapper/cl2-storage /storage xfs defaults 0 0

press “Esc” and then “ZZ” to save and exit the editor

12. Reboot your system

CODE

# reboot -n

13. Check your mounted LVM

CODE

# lsblk

14. You need to set the Storage of your VXG Server to your new LVM (/storage) on a separate disk.

Please find the full manual here.

In our case we need to:

a) Stop VXG Server if it was started.

CODE

# ./stop.sh

b) Copy your data to the new storage directory (if you need it) and remove the old docker volume for recordings

CODE

# docker volume rm vxg_server_record

c) Edit /docker-compose.override.yml file: (set your new PATH of LVM storage)

CODE

version: "3.3"

volumes:
  record:
    driver_opts:
      type: none
      o: bind
      device: /storage

d) Start VXG Server

CODE

# ./start.sh
