You used the exact same name (ubuntu-vg) for your new volume group as the old volume group. You must give them unique names. You can rename one of the groups using vgrename and its UUID.

Find the UUID with vgdisplay and then rename the volume group:
vgrename <VG UUID> new_name




root@svennd:~# fdisk -l /dev/sdd
Disk /dev/sdd: 233.8 GiB, 251000193024 bytes, 490234752 sectors

/dev/sdd2       208845 488247479 488038635 232.7G 8e Linux LVM



 (/dev/sdi1 is /boot partition, /dev/sdi2 is where the /home data resides)


Seems lvm2 tools also provide a way to check if it is lvm or not, using lvmdiskscan (/dev/sdd2 here)


root@svennd:~# lvmdiskscan
 /dev/sdb1  [       1.82 TiB]
 /dev/sdc2  [     149.04 GiB]
 /dev/sdd1  [     101.94 MiB]
 /dev/sdd2  [     232.71 GiB] LVM physical volume
 0 disks
 4 partitions
 0 LVM physical volume whole disks
 1 LVM physical volume



Fine, now let’s scan what lv’s are to be found using lvscan


root@svennd:~# lvscan
 inactive '/dev/VolGroup00/LogVol00' [230.75 GiB] inherit
 inactive '/dev/VolGroup00/LogVol01' [1.94 GiB] inherit



Since this is an old disk in an enclosure, it is not activated on system boot. So we need to “activate” this lvm volume.


root@svennd:~# vgchange -ay
 2 logical volume(s) in volume group "VolGroup00" now active



and bam, ready to mount :


root@svennd:~# lvscan
 ACTIVE            '/dev/VolGroup00/LogVol00' [230.75 GiB] inherit
 ACTIVE            '/dev/VolGroup00/LogVol01' [1.94 GiB] inherit



now to mount :


mount /dev/VolGroup00/LogVol00 /mnt/disk



success !
