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: root@desktop02:~# lsblk --scsi NAME HCTL TYPE VENDOR MODEL REV TRAN sda 2:0:0:0 disk ATA ST2000DM005-2CW102 0001 sata sdb 8:0:0:0 disk ATA WDC_WD20EZAZ-00GGJB0 0A80 sata root@desktop02:~# vgs VG #PV #LV #SN Attr VSize VFree vgubuntu 1 2 0 wz--n- <1.82t 0 vgubuntu 1 2 0 wz--n- <1.82t 0 root@desktop02:~# pvs PV VG Fmt Attr PSize PFree /dev/sda2 vgubuntu lvm2 a-- <1.82t 0 /dev/sdb5 vgubuntu lvm2 a-- <1.82t 0 root@desktop02:~# lvs LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert root vgubuntu -wi-ao---- <1.82t root vgubuntu -wi------- <1.82t swap_1 vgubuntu -wi-ao---- 976.00m swap_1 vgubuntu -wi------- 976.00m root@desktop02:~# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT loop0 7:0 0 55M 1 loop /snap/core18/1880 loop1 7:1 0 251M 1 loop /snap/gimp/292 loop2 7:2 0 161.4M 1 loop /snap/gnome-3-28-1804/128 loop3 7:3 0 251M 1 loop /snap/gimp/297 loop4 7:4 0 162.9M 1 loop /snap/gnome-3-28-1804/145 loop5 7:5 0 55.3M 1 loop /snap/core18/1885 loop6 7:6 0 255.6M 1 loop /snap/gnome-3-34-1804/36 loop7 7:7 0 217.9M 1 loop /snap/gnome-3-34-1804/60 loop8 7:8 0 62.1M 1 loop /snap/gtk-common-themes/1506 loop9 7:9 0 138.4M 1 loop /snap/inkscape/7947 loop10 7:10 0 260.7M 1 loop /snap/kde-frameworks-5-core18/32 loop11 7:11 0 43.2M 1 loop /snap/snap-store/415 loop12 7:12 0 50.7M 1 loop /snap/snap-store/481 loop13 7:13 0 30.3M 1 loop /snap/snapd/9279 loop14 7:14 0 31M 1 loop /snap/snapd/9607 loop15 7:15 0 217.5M 1 loop /snap/supertux/229 loop16 7:16 0 290.4M 1 loop /snap/vlc/1700 sda 8:0 0 1.8T 0 disk ├─sda1 8:1 0 512M 0 part └─sda2 8:2 0 1.8T 0 part sdb 8:16 0 1.8T 0 disk ├─sdb1 8:17 0 512M 0 part /boot/efi ├─sdb2 8:18 0 1K 0 part └─sdb5 8:21 0 1.8T 0 part ├─vgubuntu-root 253:0 0 1.8T 0 lvm / └─vgubuntu-swap_1 253:1 0 976M 0 lvm [SWAP] root@desktop02:~# 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.
