Hi, check amount of free space in volume group mongo_byg_pribuild. Free space in volume group is used to create snapshot of existing logical volume. Test if you can create snapshot manually (using linux commmands) before investigating - some instructions can be found on http://www.tldp.org/HOWTO/LVM-HOWTO/snapshots_backup.html Bye
