Using the command “vgcfgrestore” we can recover deleted LVM partitions. Linux keeps the backup copies of lvm configuration in the /etc/lvm/archive directory. In my scenario I have deleted 10GB lvm partition, follow the below steps to recover the LVM partition :
Step:1 First find the backed up configurations of Volume Group (my-vg)
Synatx :
As you can see in the above example correct configuration are backed up , in my case “my-vg_00002-692643462.vg” is correct file throug which I will recover my lvm partitions.
Step:2 Now recover the LVM partition using vgcfgrestore and archive file
Syntax
Ouptput would be : “Restored volume group my-vg”
Now we can mount lvm partition and check whether data is there or not.
Step:1 First find the backed up configurations of Volume Group (my-vg)
Synatx :
# vgcfgrestore --list < Volume-Group-Name >
# vgcfgrestore --list my-vg
As you can see in the above example correct configuration are backed up , in my case “my-vg_00002-692643462.vg” is correct file throug which I will recover my lvm partitions.
Step:2 Now recover the LVM partition using vgcfgrestore and archive file
Syntax
# vgcfgrestore -f /etc/lvm/archive/
# vgcfgrestore -f /etc/lvm/archive/my-vg_00002-692643462.vg my-vg
Ouptput would be : “Restored volume group my-vg”
Now we can mount lvm partition and check whether data is there or not.
