What happened on the system prior to your attempt to restart slapd? There was a script running which deleted all child entries in a subtree (~3000 entries). During that slapd crashed. I rebooted the server, but slapd doesn’t startup again. > It may be possible to resume from the previous snapshot of the DB, but most likely you'll be better of reloading a slapcat from the other master. Can I delete the files data.mdb and lock.mdb in the db directory, do a slapcat on node2 and with that output file a slapadd on node1? Would this be the recommended approach?
