Solved mount: special device /dev/VolGroup00/LogVol00 does not exist
There are times when using LVM you might come accross the error while mounting an LVM partition. The error that we are discussing here is mount: special device /dev/VolGroup00/LogVol00 does not exist.
[root@rmohan ~]# mount /dev/VolGroup00/LogVol00 /media/data
Output:
mount: special device /dev/VolGroup00/LogVol00 does not exist
Maybe in your case the VolumeGroup name would be different, so can be the LogicalVolume name.
Solved mount: special device /dev/VolGroup00/LogVol00 does not exist
In order to fix this problem I ran the standard display commands (pvdisplay, vgdisplay, lvdisplay) under LVM. However, everything looked good.
I then ran lvscan which provided some interesting results.
[root@rmohan ~]# lvscan
Output:
inactive ‘/dev/VolGroup00/LogVol00’ [5.40 TB] inherit
So it looks like the Volume Group and the Logical Volume is in INACTIVE state for the kernel.
We will have to enable the Volume Group for Kernel to be able to mount it.
The following is how we can enable a Volume Group.
[root@rmohan ~]# vgchange -ay VolGroup00
Where,
-a Controls the availability or unavailability of the logical volumes. It makes the volume available or unavailable to the kernel.
Output:
1 logical volume(s) in volume group “VolGroup00” now active
Verify the Volumes again using lvscan
[root@rmohan ~]# lvscan
Output:
ACTIVE ‘/dev/VolGroup00/LogVol00’ [5.40 TB] inherit
Kernel should now be able to mount the Logical Volume.
[root@rmohan ~]# mount /dev/VolGroup00/LogVol00 /media/data
Verify the mounts using mount or df
[root@rmohan ~]# mount
Solved mount: special device /dev/VolGroup00/LogVol00 does not exist
