thank's for your quick reply
could you give me your opinion about the set of
olcDbEnvFlags: writemap olcDbEnvFlags: nometasync
for production usage
I don't recommend nometasync for production, as an unexpected shutdown of
slapd can cause the mdb db to not be recoverable. I generally didn't have
issues with using writemap. However, unless you're seeing issues where
your write operations are taking an excessive amount of time to complete,
there's not really a need to set it, either. Given the age of the version
you are on and the fixes since then, any data collected from that release
isn't really going to be relevant. You'll need/want to gather new data
after upgrading to a current release. I'd also strongly advise exporting
(slapcat) and then re-importing the MDB databases once the upgrade is
complete to compact any excessive freespace due to the release you were on.
