How to add disk in azure

  1. On the Disks pane, under Data disks, select Create and attach a new disk or attach an existing disk.

  2. Enter a name for your managed disk. Review the default settings, and update the Storage type, Size (GiB), Encryption and Host caching as necessary.

Once connected to your VM, you need to find the disk. In this example, we're using lsblk to list the disks.

Format the drive mkfs.xfs /dev/sdc

Partition Create fdisk /dev/sdc

You can create/resize/delete LVM partitions.

No need to reboot the system to make the kernel aware of the newly created or resized partitions.

If you have more than one hard disk, Logical Volumes can extend over more than one disk

  1. First list the hard disk

Check the PV, VG, and LV.

PV- Physical Volume

VG- Volume Group

LV- Logical Volume

Create PV & SV & LV

If mounted the drive is not possible to create LVM

First, unmount the drive sudo umount /dev/sdc

Create PV & SV & LV

Check PV,VG,LG

Check the path fdisk -l

Format the disk

Check the path

Finally mount a drive

sudo mount /dev/mapper/Test-Create /Data

/dev/mapper/Test-create - OS understands the name

/dev/Test/Create - Logical Volume understand the name
