Hello,
I get the following error with lvm2.02.98:
-----------
#/sbin/vgdisplay --units k -v 'system'
--- Volume group ---
VG Name system
System ID
Format lvm2
Metadata Areas 1
Metadata Sequence No 13
VG Access read/write
VG Status resizable
MAX LV 0
Cur LV 0
Open LV 0
Max PV 0
Cur PV 1
Act PV 1
VG Size 104669184.00 KiB
PE Size 4096.00 KiB
Total PE 25554
Alloc PE / Size 0 / 0 KiB
Free PE / Size 25554 / 104669184.00 KiB
VG UUID Qs0uaZ-L88n-tC7T-fZQj-sgJY-2yRX-Dlt2Cr
--- Physical volumes ---
PV Name /dev/sda3
PV UUID wzGjXi-F2lT-d2d4-l5a6-EmfM-W838-YxaFIh
PV Status allocatable
Total PE / Free PE 25554 / 25554
-----------
VG system is empty, but still:
-----------
# /sbin/vgremove 'system'
-----------
failes with status code 5, which means 'can't remove volume group
containing logical volumes' (from man page).
Looks like a bug in vgremove?
Best regards,

Possibly. Could you fill in these gaps in the puzzle:
0. Which distro?
1. Do a lvmdump for bug report:
lvmdump -ma
2. Try with verbose
vgremove -vvvv &> vgremove-dirty.out
3. Check if lvmetad is running:
ps aux | grep lvmetad
3.1 if so, the issue is likely to go away after restarting it. If you
`gcore` or `kill -SEGV` it to get a core dump it may help us.
3.2 do another lvmdump here, to get "updated" data after lvmdump restart
3.3 retry vgremove
vgremove -vvvv &> vgremove-reloaded.out
4. pastebin the vgremove-dirty.out and we will be able to tell more then.

Any chance the FS containing /etc/lvm is mounted read-only?
If so it may fail. There is a bug as no error is reported in that
situation. See backup section of lvm.conf - set backup and archive to
point to a writable FS.
If not, could you send a tarball with /etc/lvm: `tar czf lvmdump-etc
/etc/lvm/`
Joining us on IRC: #lvm @ freenode guarantees faster answers.

Well, no.
Actually, I am not performing those commands manually.
It is the openSUSE 12.3 installer (YaST2), that performs a sequence of
commands during installation. It is told to create a new VG on an
existing LVM partition. Hence, it first removes all LVs in the existing
VG, then tries to remove the existing, empty VG using 'vgremove system'.
I tried to strip the series of commands from the YaST2 logs:
-------------
"/sbin/lvremove -f -A n '/dev/system/var_log'"
"/sbin/lvremove -f -A n '/dev/system/var'"
"/sbin/lvremove -f -A n '/dev/system/usr'"
"/sbin/lvremove -f -A n '/dev/system/tmp'"
"/sbin/lvremove -f -A n '/dev/system/slash'"
"/sbin/lvremove -f -A n '/dev/system/nobackup'"
"/sbin/vgremove 'system'"
-------------
=> Fails with exit code 5
openSUSE 12.3 is using
LVM version: 2.02.98(2) (2012-10-15)
Library version: 1.02.77 (2012-10-15)
Driver version: 4.23.0
Note that the EXACTLY same sequence of commands works OK for openSUSE
12.2 using
LVM version: 2.02.84(2) (2011-02-09)
Library version: 1.02.63 (2011-02-09)
Driver version: 4.22.0
