Hi@akhtar,

To increase the Logical Volume Size, the Linux system has one command named lvextend. This command helps to increase the size of the volume according to our needs. You can go through the below-given example.

[root@localhost ~]# lvextend --size +5G /dev/myvg/mylv
  Size of logical volume myvg/mylv changed from 50.00 GiB (12800 extents) to 55.00 GiB (14080 extents).
  Logical volume myvg/mylv successfully resized.
[root@localhost ~]# lvdisplay myvg/mylv
  --- Logical volume ---
  LV Path                /dev/myvg/mylv
  LV Name                mylv
  VG Name                myvg
  LV UUID                yEPJZN-5Ucq-sL2u-VEKU-Nlpt-iTMh-HrH2uf
  LV Write Access        read/write
  LV Creation host, time localhost.localdomain, 2020-07-08 14:08:36 -0400
  LV Status              available
  # open                 0
  LV Size                55.00 GiB
  Current LE             14080
  Segments               2
  Allocation             inherit
  Read ahead sectors     auto
  - currently set to     8192
  Block device           253:3

I hope this will help you.
