Mehdi S commented on DIRSERVER-2172:
------------------------------------

Hi,
We are facing same problem with repair command, after repair process we lose many users &
roles (more than 50%) in PRODUCTION and we have not yet a replication, so no way to restore
data corrupted :(

Below unsuccessful workarounds used "Independently" :
- Repair command : data missed after repair 
- Partition-plumber + remove all  our_instance/partitions/*.db except master.db 
- Export Data to reinject in clean partition : ldapsearch returns some data but not all

NB: when we try to insert an old user already deleted, apacheDS is responding that "entryalready
exists", we have find some traces in our_instance/partitions/1.3.6.1.4.1.18060.0.4.1.2.50.db
(I think apacheRdn attribute) but not in the master.db

have you any suggestion ? ApacheDS still running in production but indexes are broken.


ENV : unix redhat 5  & Java 8 & ApacheDS 2.0.0-M22

> We have upgraded apacheds from 2.0.0-M23 assuming that will fix the issue with data getting
corrupt but we are still facing the same issue.The apacheds server keeps running but data
does not load fully from front end like 400 users instead of actual 3000+ users.
> -> As a workaround we take backup of partition daily and when the issue occurs we
replace the partition from backed-up partition and restart the server.
> -> From apacheds.log we get below error trace-
