OK, I get that. So, when using corelog, I won't risk loosing data.

But, when using corelog, what would be the expected delay at bootup?

Also, if I use a log on disk, what happens if I put it on the same disk
as either the master or the copy? And, if I do that, should it be on
it's own PV, or on it's own LV?

Best,
Koen
