How to solved mount: unknown filesystem type 'LVM2_member'
This mean the disk type is LVM
[[email protected] ~]# mount /dev/sdc3 /nfsserver
mount: unknown filesystem type 'LVM2_member'
[[email protected] ~]# 
Check the lvm disk by running following command
[[email protected] ecpa]# lvscan
  ACTIVE            '/dev/centos/root' [<66.41 GiB] inherit
  ACTIVE            '/dev/centos/home' [24.41 GiB] inherit
  ACTIVE            '/dev/centos/swap' [7.88 GiB] inherit
  inactive          '/dev/centos_old/root' [<1.91 TiB] inherit
  inactive          '/dev/centos_old/swap' [3.89 GiB] inherit
[[email protected] ecpa]# 

Activate the vg and check the lv path
[[email protected] ~]$ sudo vgchange -ay centos_old
  2 logical volume(s) in volume group "centos_old" now active
[[email protected] ~]$
[[email protected] ~]$ sudo lvscan
  ACTIVE            '/dev/centos/root' [<66.41 GiB] inherit
  ACTIVE            '/dev/centos/home' [24.41 GiB] inherit
  ACTIVE            '/dev/centos/swap' [7.88 GiB] inherit
  ACTIVE            '/dev/centos_old/root' [<1.91 TiB] inherit
  ACTIVE            '/dev/centos_old/swap' [3.89 GiB] inherit
[[email protected] ~]$

Mount the volume
[[email protected] ~]$ sudo mount /dev/centos_old/root /nfsserver
[[email protected] ~]$
[[email protected] ~]$ df -h

  1. I don't see any inactive VGs.
    I only see the following:
    # lvscan
    ACTIVE '/dev/centos/swap' [820.00 MiB] inherit
    ACTIVE '/dev/centos/root' [<6.20 GiB] inherit
