Jeff, I'm curious to what kind of testing you've done with LVM. I'm not currently trying any backup/restore stuff, but I'm running our DBT-2 workload using LVM. I've started collecting vmstat, iostat, and readprofile data, initially running disktest to gauge the performance. For anyone curious, I have some data on a 14-disk volume here: http://developer.osdl.org/markw/lvm/results.4/log/ and a 52-disk volume here: http://developer.osdl.org/markw/lvm/results.5/data/ Mark >Jeff <threshar@torgo.978.org> writes: > > Idea #1: > Use an LVM and take a snapshop - archive that. > From the way I see it. the downside is the LVM will use a lot of space > until the snapshot is removed.
