MySQl and LVM

[Shain Miley]

Hello,
I am trying to  plan we in advance our methods for backup and recovery 
of our new MySQL replication cluster.  After doing some research it 
looks like a lot of people are using LVM snapshots as their backup 
solution.  We currently have two MySQL servers with 2 300 GB (Raid 1).  
What I am confused about is the best disk layout to use at this point.

Do I need to create a separate volume for the snapshots?  Can anyone 
provide any suggestions on disk layout for two disks of this size?

Thanks,

Shain
