Subject: snapshots: COW drive capacity and monitoring space usage
Date: Tue, 29 Sep 2009 17:19:35 +0900	[thread overview]
Message-ID: <4AC1C317.6060406@bfn.org> (raw)

After having built my own distro up from source code (just to see if I 
could), I've got snapshotting set up successfully on my system using the 
kernel device mapping facility, dmsetup, and a COW drive.  I understand 
from my reading that it is possible for the COW drive to run out of 
space while it is in use.  Since it is not mounted and does not use a 
filesystem as far as I know, I am wondering how one might go about 
deciding on how big a drive to use, and monitoring space usage.  Any 
information on this would be most appreciated.
