this ensures you have consistent entryCSN and contextCSN
That's of course right.
But that will also more than double the time needed to load a backup
on a mirrormode setup.
This procedure should only be needed if the LDIF doesn't already contain
correct CSNs. If you're loading a backup from a 2.4 slapcat you can just
slapadd it on all servers at once.
My understanding is that he was loading LDIF from 2.3, which has a
different format for CSN. So the first run with -S and -w was intended
to initialize CSN info in 2.4 format with the SID of the first master.
This would probably require to remove entryCSN values from the original
I've done as above.
"slapadd -S 1 -q -w" on server-1 (Server-ID 1)
Then slapcat on server-1
I would have expected the entryCSN values in the output to now be with
SID 1, but they look like this:
Then contextCSN is also with SID 0:
Though that surpised me I impirted the LDIF to server-2 (SID 2) and
replication seems to work.
However, after the first change from server-1 has been replicated to
server-2, there are now 2 contextCSN's on server-2:
... the last one with SID 1.
This is not the behaviour I would have expected.
