Oracle Linux: How to move LVM VG and LV to a new Oracle Linux Instance

edited Aug 8, 2024 11:13AM in Linux

Applies to: 

Oracle Cloud Infrastructure - Version N/A and later 

Linux x86-64 

Oracle Linux 7 – Oracle Linux 9. 

Goal: 

Move a Volume Group and its Logical Volumes to a new Oracle Linux instance  

Solution: 

Execute these steps on the First Oracle Linux instance as root user (sudo su -) 

1 ) Unmount any filesystems that use the affected VG and its LVs. This is a requirement. In this case:

# umount /reports 
# umount /docs 

2) Make the VG inactive:

# vgchange -an dataVG 
  0 logical volume(s) in volume group "dataVG" now active 
 
# vgexport dataVG 
  Volume group "dataVG" successfully exported 

3) Determine the PV(s) and LV(s) 

Howdy, Stranger!
