LVM snapshot

[Russell Coker <russell coker com au>]

lvcreate -s -n snap -l 10 /dev/V0/fc2

/dev/V0/fc2 is the root file system for my FC2 machine.  I ran the above 
command to make a snapshot of it named /dev/mapper/snap and now all access to 
the root FS is blocking.  I had "less" running before this and I can still 
scroll.  I expect that "-l 10" is enough as my PE size is 16M and I don't 
expect to make more than 160M of changes before the backup is complete.

Did I do something wrong or is this an indication of a kernel bug in LVM?
