Introducing LVM drives (storage) to new operating system.
====================================
When lvm drives are introducted to a new operating system. They will not be detected logical volumes.
vgscan - Will detect all the available logical volumes and make necessary enteries in the lvm configuation.
# vgscan Reading all physical volumes. This may take a while... Found volume group "lvm_data3" using metadata type lvm2
Found volume group "lvm_data2" using metadata type lvm2
Found volume group "lvm_data1" using metadata type lvm2
# lvscan
inactive '/dev/lvm_data3/lvm_bkp' [271.00 GB] inherit
inactive '/dev/lvm_data2/lvm_stores' [169.00 GB] inherit
inactive '/dev/lvm_data1/lvm_redo' [60.00 GB] inherit
inactive '/dev/lvm_data1/lvm_log' [30.00 GB] inherit
inactive '/dev/lvm_data1/lvm_conf' [20.00 GB] inherit
inactive '/dev/lvm_data1/lvm_mysql' [50.00 GB] inherit
inactive '/dev/lvm_data1/lvm_index' [25.00 GB] inherit
inactive '/dev/lvm_data1/lvm_lgr' [35.00 GB] inherit
The devices are detected as inactive to make the devices active
vgchange -ay lvm_data3
vgchange -ay lvm_data2
vgchange -ay lvm_data1
lvscan will show all the drives as active.

you should be able to mount the filesystem now
