[Fedora-directory-users] Replication: How long does it take untilreplicated servers are in sync after one of them came up....

[Reinhard Nappert]

Yes,

I know that you can set nsds5ReplicaUpdateSchedule to "0000-2359
0123456", which forces the update, but this would mean that I know that
the other box was down.

Is there are different way to do it?

Thanks,

The interval uses a backoff strategy - it first tries after 1 second,
then after 2 seconds, then after 4 seconds, etc. doubling every time
until it hits a maximum of every 5 minutes.  This is not configurable,
but there is a way to send updates now which will break it out of the
wait/backoff.
