This is an old thread but I’m running into this issue and was wondering if there was ever a resolution to this.
Tldr - My master failed and was not able to start up due to the dse.ldif being a zero byte file and the .bak file was unusable as well. Ended up using the startOK file and that got my IPA master back up. I didn’t find out till a week or so later that my replication has stopped working and I’ve been trying to resolve this ever since. The error I’m getting when trying to set up a new replica is the error in the subject. These are the last couple entries in the journal logs for the dirsrv service : May 20 16:11:40 ns-slapd[5273]: [20/May/2021:16:11:40.900845676 +0000] - NOTICE - bdb_start - Detected Disorderly Shutdown last time Directory Server was running, recovering database.

I would like to NOT rebuild the entire IPA infrastructure if I can avoid it to get replication back up and running so any help would be greatly appreciated. Thank you. Sinh Lam
