Several seconds delay, but services will continue to work.

The LVM snapshots need 500m free space.

Use option --dumpdir, for example
vzdump --dumpdir /space/backup --suspend 777

The LVM snapshot needs space on the VG you want to
take the snapshot. (See LVM2 howto and mauanl pages).
So if you want to use snapshot you must provide some
free space on that VG (Volume Group). You can do that by
adding another partition/disk to that VG (man pvcreate).
