slapcat and BDB transaction-logs
I'm trying to migrate a directory from OpenLDAP 2.3.x to an OpenLDAP 2.4.11 test installation. My LDAP-experience is less than extensive, but I've run slapcat on the old base, and am now trying to import it back into 2.4.11 with slapadd. The base is large enough that the import will take several days at the current rate (3gb LDIF/approx 4 million entries), and so I can't monitor the process at all times.
My problem is with the backend transaction logs, though. These are chucked out at a rate of approximately one per minute until the disk runs out of space. I did a quick google on the issue and found that you should be able to remove logs not currently involved in any transactions by running db_archive -d (http://www.oracle.com/technology/documentation/berkeley-db/db/ref/transapp/logfile.html
). I've also tried adding a set_flags DB_LOG_AUTOREMOVE in my DB_CONFIG with no luck. Then I figured I could set up a cronjob to run db_archive hourly, but when I run db_archive -d (or more to the point, slapd_db_archive2.4 -d, as I've installed using Buchan Milne's RPMs), not a single log-file is removed. Moreover, none of the *.bdb files are increasing in size while slapadd is running, only additional log-files and __db.001 etc.Does slapadd basically do all adds in one huge transaction before committing at the end, or am I doing something wrong? Can I simply erase log-files with rm on the fly instead? The checkpointing in slapd.conf is set to 256k/5min as per default. Anything else I'm missing?
