When trying to create a snapshot (per the handbook at <http:// 
www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/snapshots.html>),  
the creation of the snapshot fails:

/mnt/big# mount -u -o snapshot /mnt/big/.snap/"`date`" /mnt/big
mount: /mnt/big: Filesize limit exceeded

It takes about a minute to fail. This is a 300GB drive:

/mnt/big/.snap# df -h /mnt/big
Filesystem            Size    Used   Avail Capacity  Mounted on
/dev/mirror/gm0s1a    269G    134G    113G    54%    /mnt/big

Am I doing something wrong?
