This is a terrible idea. Note that if you have say 40mb/sec on regular lvm partition, you will be reduced to about 10mb/sec on the cow. also, major fs intensive things are likely to kill your cow. (i have noticed nessus completely ruining a lvm snapshot). because of this, there is work being done to create a real cow fs in replacement of lvm snapshots. ~ chris On Fri, 2005-07-29 at 16:38 +0100, Jason McCandless wrote: > I have a number of xen domains running on lvm cow snapshots.
