[dm-devel] Problem when creating snashots

[The MoonSeeker <themoonseeker gmail com>]

Hi,

I'd like to create many snaphot of an image but I've got when I  
attemp to create the 32th snapshot :

root B03:/diplome# lvcreate -s -L150M -n 232 /dev/openvz/vps-core
  Rounding up size to full physical extent 152.00 MB
  device-mapper: reload ioctl failed: Ne peut allouer de la mémoire
  Failed to suspend origin vps-core

I don't understand the error..

This what I get when scaning the LVM :

root B03-PC:/diplome# lvscan
  ACTIVE   Original '/dev/openvz/vps-core' [200.00 MB] inherit

  ACTIVE   Snapshot '/dev/openvz/230' [152.00 MB] inherit
  ACTIVE   Snapshot '/dev/openvz/231' [152.00 MB] inherit

What can I do? Is it some limitation when snapshoting?
