Identifying Unused VG

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi All,

I am new user of LVM.  At home, in a desktop machine, I installed Ubuntu
20.04 LTS and while doing so I opted for LVM.  This desktop computer has
2 hard disks.  I want to remove 1 hard disk and use it for another
computer.  But I need to remove the hard disk without loss of data.  The
problem now is that there are two VG listed, while I think it should be
only one.  How to identify the unwanted VG? Maybe this is because of
multiple attempts at installation.  Any help on this is much
appreciated.

Here are some of the output of the commands in that desktop:

Since both the VG is named as "vgubuntu", I am wondering how to identify
the unused or unwanted VG.  And I need to identify which hard disk (sda
or sdb) I can remove.  And what I need to do before unplugging it.

I would appreciate if you people can point me in the right
direction. Thank you.

Rgds,
anna
