Centos - mounting LVM partitions on another system

One thing that we have to do from time to time is to mount LVM volumes from a rescued hard drive on another machine.

To do so yourself, follow these steps.

Once hardware is attached to another linux machine enter the command-line as follows:

lvm lvs - This will show you the avaialbe LVM volumes that you can work with

lvm vgchange --ignorelockingfailure -P -a y - this will allow you to mount volumes after disabling locking issues

lvdisplay - this will show you avaiable volumes

lvmdiskscan - this will scan the LVM disk information

lvdisplay

vgscan

pvscan

vgchange SubstituteYourLVMVolumeNameYouWantToMountHere -a y

Next you will want to make and mount that vokume as a directory so that you can read from it

mkdir /mnt/data

mount /dev/SubstituteYourLVMVolumeNameYouWantToMountHere/MainLV00 /mnt/data

You will now be able to read off recovered data from your new mount point!
