Hi,

LVM 2.02.39-7 on Debian Lenny 64 bit with Xen 3.2-1

I have a few LVs that I can't get rid of:

server1:/# ls -al /dev/mapper/*oa*
brw-rw---- 1 root disk 254,  7 2011-07-22 19:40 /dev/mapper/d-pdc.oa.c
brw-rw---- 1 root disk 254, 78 2011-10-30 13:04 /dev/mapper/d-pdc.oa.cp1
server1:/# kpartx -l /dev/mapper/d-pdc.oa.c
d-pdc.oa.c1 : 0 71103627 /dev/mapper/d-pdc.oa.c 63
server1:/# kpartx -d /dev/mapper/d-pdc.oa.c
server1:/# kpartx -d /dev/mapper/d-pdc.oa.c1
failed to stat() /dev/mapper/d-pdc.oa.c1
server1:/# lvs | grep oa
  pdc.oa.c         d    -wi-ao  37.00G                                    

There were a couple of other open LVs that I could successfully delete
using the method described above but this one seems to be a bit harder
to convince. The LV surely isn't open by anything I can identify (not
mounted etc), but the kernel seems to think otherwise.

Any suggestions?

kind regards,
Jan
