Zimbra already does all of these things using writemap. You could look
at what we've done in relation to this. But I agree with Howard,
there's generally little advantage to downsizing the writemap.
Ok, noted, downsizing is not an appropriate tactic. That means
making a reasonable good guess to start with, something short of
'use the whole disk'.
You've suggested writemap in response to other questions I've asked
on this list; I think I shall take the hint. :)
Is your OS a BSD or Linux?
Last time I tried on BSD, it didn't use sparse files with writemap like
Linux does. It just made a massive file on disk of the size specified for
the maxsize. I.e., BSD didn't correctly support sparse files with writemap.
