[linux-lvm] LVM snapshot limits

[Shaun Kruger]

Thanks for the information.  I'll post that to my redhat support ticket and 
see if they can help me with a more immediate fix.

This copy on write issue had already occoured to us.  We were going to roll 
out with the concept of a persistent or nonpersistent database instance.  The 
nonpersistent ones were going to be removed before refreshing the data on the 
main database source.  There is another script that recreates all the 
developer instances after the update is complete.
