Re: Index Add Failures
Is it possbile to use MMR to my advantage to switch over? For example, take down 1 of the servers, switch the db config from bdb to mdb, and then restart with a blank database (withÂappropriateÂstructure) and have the MMR take care of backfilling the mdb entries? Then I wouldn't have to export to ldif, convert the db, and reimport while possibly loosing data from the other systems.

I would suggest back-mdb in OpenLDAP 2.4.33 over back-hdb, yes. ÂIt will remove these deadlock issues entirely. ÂWhen you configure the back-mdb backend in cn=config, be sure to have:

Ok, I have been running 2.4.32 for some time with no issues. Yesterday, 2
different servers (both part of a 4-way MMR) produced an "index add
failure" and an "index delete failure". I went back over the bdb
DB_CONFIG Settings (listed below) and everything looks nominal to me.
Would it just make more sense to switch from bdb to mdb instead of
troubleshooting these "random" errors too much? I also noticed that the
number of "deadlocks" corresponds to the number of errors that were
produced. Is there correlation there?
set as well. ÂThis makes back-mdb writes significantly faster than writes to back-bdb/hdb. (Some 2x faster in my testing so far).
