hi,

i have a strange problem, under (Xen enabled) kernel 2.6.18:

lvscan:

  /dev/dm-33: open failed: No such device or address
  /dev/dm-34: open failed: No such device or address
  /dev/dm-36: open failed: No such device or address

[...]
  ACTIVE            '/dev/neko/angelica-disk-snap' [500.00 MB] inherit
  ACTIVE            '/dev/neko/rico-disk-snap' [500.00 MB] inherit
  ACTIVE            '/dev/neko/triela-disk-snap' [500.00 MB] inherit

ls -l /dev/mapper/*snap
b--------- 1 root root 253,  1 Jan 12
07:35 /dev/mapper/neko-angelica--disk--snap
b--------- 1 root root 253, 38 Jan 18
07:35 /dev/mapper/neko-rico--disk--snap
b--------- 1 root root 253, 39 Jan 20
07:35 /dev/mapper/neko-triela--disk--snap


i can't remove these snapshots, because, they don't exists
in /dev/neko/... (my vg is called neko)

I absolutely don't now, why and when it happens. I did not rebooted the
system, cause of bad time. Does anybody knows, what could be the reason?

Linux henrietta 2.6.18.8-xen #2 SMP Mon Jan 5 19:11:14 UTC 2009 x86_64
GNU/Linux

System is Debian Etch with kernel from xen.org (xen 3.3.1)
