Step Past Times Pace Deed Lvm ( Vg-Volume Grouping , Pv-Physical Voulme As Well As Lv- Logical Volume) To Approximately Other Linux Organisation

LVM Move: - We tin motility entire LVM Volume grouping to approximately other Linux System. 
It may require when yous are going to upgrade your electrical flow OS to the latest or at that spot is approximately lawsuit alongside electrical flow Server hardware or going to role novel server hardware.

Why Move LVM: -
1- There is approximately hardware lawsuit alongside electrical flow server
2- We convey novel Server hardware
3- Current OS is onetime version

Prerequisites:- 
1- Influenza A virus subtype H5N1 user alongside sudoers access over onetime System
2- user alongside sudoers privileges over novel System
Move LVM: - We need to perform next steps to motility LVM

My Current scenario as follows:
VG Name:  VG01

PV Name:  /dev/sdb1 in addition to /dev/sdc1 

LV Name:  LV01 in addition to LV02 

 Note: -first, brand certain no i is accessing the file on the active book inwards the book grouping nosotros are going to move.
Step 1: -  Unmount LV logical volume
Before, nosotros commence moving LVM necessitate to unmount let's role below ascendence to unmount LV

root@Server16: # umount /mnt/FLV

Step 2: - Make VG inactive 
Now nosotros necessitate to brand VG inactive, role below command.

root@Server16: # vgchange -a n VG01 

Step 3: - Export Volume Group

root@Server16: # vgexport VG01 Volume grouping VG01 is exported Cannot procedure book grouping VG01

After exporting VG, the Physical Volume volition exhibit upward equally beingness exported book grouping when yous volition execute command pvscan.

Step 4: - Shutdown System in addition to unplugged disk
After System Shutdown unplugged both the disk. Let's role init 0 ascendence to shutdown system.

Step 5: - Plugged disk to novel organization in addition to ability it on 
After putting both the disk to the novel system, I am going to ability it on in addition to volition exhibit yous how to import Volume Group.
Disk , VG in addition to LV details equally follows:

Step 6: - VG Import 
After putting all the disk to novel organization nosotros necessitate to import Volume Group, let's role below ascendence to Import VG using ascendence vgimport

root@US16: # vgimport VG01   Volume grouping "VG01" successfully imported 

Step 7: - Activate Volume Group

After successful import of VG, We necessitate to active Volume Group using ascendence below

root@US16: # vgchange -a y VG01   ii logical volume(s) inwards book grouping "VG01" instantly active

Step 8: - Create mountain point 

Now Volume Group has successfully import in addition to activated, let's practise mountain betoken then nosotros tin mountain in addition to commence using Logical Volume.

root@US16: # mkdir /mnt/lvm1 root@US16: # mkdir /mnt/lvm2 

Mount betoken successfully created.

Step 9: - Mount Logical Volume

root@US16: # mount /dev/VG01/LV01 /mnt/lvm1/ 

Step 10:  Check onetime information of LV01 Logical Volume

Volume Group Import has done successfully, in addition to Logical Volume mounted equally well.

let's cheque existing information inwards the mounted LV.

Volume Group has successfully Imported to novel organization in addition to working equally expected. We tin brand fstab entry to mountain Logical Volume permanently.
Step 11: - Make Fstab entry to mountain LV permanently
Let's role below ascendence to mountain it permanently.

root@US16: # vi /etc/fstab

Append trouble below inwards the goal of fstab file

/dev/VG01/LV01  /mnt/lvm1       ext4    errors=remount-ro 0     0

Your fstab file looks similar below

Step 12: - Use ascendence mountain -a to apply changes
After making alter inwards fstab file nosotros necessitate to restart organization to apply changes, merely nosotros tin role ascendence mountain -a to apply changes without restart system.

root@US16: # mount -a

Logical Volume has been successfully mounted permanently.

!!!That's all close VG Moving!!!! Thank yous then much for reading.
