Hi Martin,
Can you tell me how I extend the LVG. I have tried, but it's not right.

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
