LV_size / region_size = region_cnt region_cnt / 8 ~= number of bytes necessary for the log So, 100GiB LV / 512kiB region size = 200,000 regions 200000 / 8 = ~25kiB log It takes quite a bit to get the log to be large and if that happens and you don't like it, you can always increase the region size. brassow On Apr 21, 2013, at 2:37 PM, Ben wrote: > In my testing of LVM2 I have seen a mirror log up to 512KiB.
