Subject: [linux-lvm] determining snapshot overhead
Date: Wed, 14 Jan 2015 08:24:30 +0100 [thread overview]
Message-ID: <54B619AE.6020704@shockmedia.nl> (raw)
Hello,
I am trying to create snapshots of thick volumes that can't break
because they overflow (thin volumes are not an option right now). I
can't find information on how to calculate (in advance) the metadata
overhead of a snapshot when all blocks in the origin volume are changed
(e.g. the snapshot is 100% full). Is there a way to do this?
