LVM

Create LV#

• Display all PVs, VGs and LVs:

  sudo pvs; sudo vgs; sudo lvs;

• Verify devices in /dev/sd*:

  ll /dev.sd*

• Create PV:

  sudo pvcreate /dev/sdb

• Create VG:

  sudo vgcreate <vg_name> <pv>

• Create LV:

  sudo lvcreate -l 100%FREE -n <lv_name> <vg_name>

• Format LVM partition:

  sudo mkfs.xfs /dev/<vg_name>/<lv_name>

• Mount LVM:

  sudo mount /dev/<vg_name>/<lv_name> <mnt_destination>

• Add LVM to fstab:

  echo '/dev/<vg_name>/<lv_name> <mnt_destination>  xfs  defaults 0 0' | sudo  tee -a /etc/fstab ; sudo mount -a

Upscale LV#

• Upscale the managed disk (Azure).
• Extend the PV:

  sudo pvresize /dev/sd*

• Extend the LV:

  sudo lvextend -l +100%FREE /dev/VGName/LVName

• Resize the filesystem:

  sudo xfs_growfs /mount/point
