The filesystem is ext3 on RHEL5.
-q enable quick (fewer integrity checks) mode. Does fewer
tency checks on the input data, and no consistency checks
writing the database. Improves the load time but if any
or interruptions occur the resulting database will be
That last bit was enough for me not to use the -q, but it did reduce
load time to 17 minutes.
The performance of slapadd is significant, but what about syncrepl?
Why is the consumer reviewing every object? Reviewing "-q", I discovered
-w write syncrepl context information. After all entries
added, the contextCSN will be updated with the greatest
And that looks like an option that would prime my syncrepl info. So
slapadd -q -w -l SLAPCAT.LDIF
took 14 minutes to build and then 3 minutes to close the databases.
This consumer has the same hardware as the provider that took 35
minutes to rebuild the database.
That "slapadd -w" looks like the fix. Would someone confirm or reject
The provider's log file still shows it's reviewing many records. I
guess it's not returning them. Will the log file show the DNs of
results (as opposed to visited)?
I restarted the provider with less logging; logs of a full syncrepl
scans are sucking up disk space. Only 5 or 6 records would have changed.
Is it normal for the provider to visit many (all?) objects even when
the consumer would have a very current CSN?
Thanks for your help,
