Hi Guys,

I have created one Logical Volume in my Linux system. I am trying to display the Logical Volume. But it is showing me the below error.

[root@localhost ~]# lvdisplay mylv
  Volume group "mylv" not found
  Cannot process volume group mylv

How can I find my Logical Volume?

Hi@akhtar,

You got this error because your command is not correct. You created your Logical Volume from your Volume Group. So you need to tell your Volume Group name as well. You can see the below command.

  • If I try with only Logical Volume name. It gives me the below output.

[root@localhost ~]# lvdisplay mylv
  Volume group "mylv" not found
  Cannot process volume group mylv
  • But I give my Volume Group name, it gives me the right output.

[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
