====== LVM configuration in ASMS ======
//
by Patrik Hermansson
//

This is the LVM setup for the Algosec Appliance, change accordingly. 
This will extend the / (root) partition to 50GB and put the rest of the disk(s) in /data partition.

===== up to A30.10 version =====
==== Fix the LVM on the devices ====
Lists all disks in the system (as fdisk -l)
  lsblk

  parted /dev/sdb

Moves from msdos to guided partition table for disks over 2TB
      mktable GPT
Creates a partition of 50GB
      mkpart 0 1 50000 
Create a partition of the rest of the disk
      mkpart 0 50001 100%
Lists all disks in the system (as fdisk -l)
  lsblk
Creates the physical volumes of the new partitions
  pvcreate /dev/sdb1
  pvcreate /dev/sdb2

Extend the volume group /dev/vg_algsoec with the new physical volumes
  vgextend /dev/vg_algosec /dev/sdb1
  vgextend /dev/vg_algosec /dev/sdb2
  
Extend the logial volumes with the new partitions (-r will extend automaticly)
  lvextend -r /dev/vg_algosec/vg_system /dev/sdb1
  lvextend -r /dev/vg_algosec/vg_data /dev/sdb2
  
if not -r extends the logical volumes automaticly do the following

for ext4 filesystem
  resize2fs /dev/vg_algosec/vg_system
  resize2fs /dev/vg_algosec/vg_data

for xfs filesystem
  xfs_growfs /dev/vg_algosec/vg_system
  xfs_growfs /dev/vg_algosec/vg_data

To check the filesystem expends ok via watch per second
  screen
  watch -n 1 -d "df -hT"
  ip addr
  watch -n 1 -d "df -hT"


===== For ASMS V32 => =====

//**Differences is that volume group and logical volumes have new names / different locations.**//
