Creating disk partitioning for a Microsoft Azure virtual machine

Last Updated : Jun 10, 2026 |

About this task

Avaya Aura® Device Services requires a specific disk layout that includes several disk partitions and logical volumes. Use this procedure to create appropriate disk partitioning.

Before you begin

Procedure

  1. Log in to the virtual machine as the root user using an SSH connection.
  2. To extend the file system, run the following commands: 
    lvextend -L +8G /dev/rootvg/rootlv
xfs_growfs /dev/rootvg/rootlv

lvextend -L +7G /dev/rootvg/homelv
xfs_growfs /dev/rootvg/homelv

lvextend -L +7G /dev/rootvg/tmplv
xfs_growfs /dev/rootvg/tmplv
  3. To create the required directories, run the following commands: 
    mkdir -p /var/log/Avaya
mkdir -p /media/data
mkdir -p /media/cassandra
  4. To create the required physical volumes and volume groups for these volumes, run the following commands: 
    pvcreate -f /dev/sdc
vgcreate disk2_vg /dev/sdc
pvcreate -f /dev/sdd
vgcreate disk3_vg /dev/sdd
pvcreate -f /dev/sde
vgcreate disk4_vg /dev/sde
  5. To create logical volumes in the volume groups, run the following commands: 
    lvcreate -l100%FREE -n application_log /dev/disk2_vg
lvcreate -l100%FREE -n data /dev/disk3_vg
lvcreate -l100%FREE -n cassandra /dev/disk4_vg
  6. To create a logical volume for the /opt directory, run the following command: 
    lvcreate -L 8G -n optlv /dev/rootvg
  7. To create a file system for the /dev/sda3 partition and mount the file system, run the following commands: 
    mkfs.xfs /dev/rootvg/optlv
mount /dev/rootvg/optlv /opt
echo "/dev/rootvg/optlv /opt xfs defaults 0 0" >> /etc/fstab
  8. To create a file system for the /dev/sdc partition and mount the file system, run the following commands: 
    mkfs.xfs /dev/disk2_vg/application_log
mount /dev/disk2_vg/application_log /var/log/Avaya
echo "/dev/disk2_vg/application_log /var/log/Avaya xfs defaults 0 0" >> /etc/fstab
  9. To create a file system for the /dev/sdd partition and mount the file system, run the following commands: 
    mkfs.xfs /dev/disk3_vg/data
mount /dev/disk3_vg/data /media/data
echo "/dev/disk3_vg/data /media/data xfs defaults 0 0" >> /etc/fstab
  10. To create a file system for the /dev/sde partition and mount the file system, run the following commands: 
    mkfs.xfs /dev/disk4_vg/cassandra
mount /dev/disk4_vg/cassandra /media/cassandra
echo "/dev/disk4_vg/cassandra /media/cassandra xfs defaults 0 0" >> /etc/fstab
