Hi,
Today I tried 389-base 1.4.4.17 for a fix of retro cl trimming [1]
Unfortunately the ns-slapd got into some sort of deadlock, I think.
Anyway, I reverted 389-base back to 1.4.3.23.
Yeah the replication changelog was moved in 1.4.4, so by downgrading you
most likely corrupted the changelog. Stop the server, remove the old
changelog: /var/lib/dirsrv/slapd-INST/db/changelogdb, and the new one
/var/lib/dirsrc/slapd-INST/db/userroot/replication_changelog.db
Hmm. I don't have these (files?).
/var/lib/dirsrv/slapd-INST/db/changelogdb/ <=== this directory, and
its contents, are the 1.4.3 replication changelog (typically defined in
cn=changelog5,cn=config).
We don't have cn=changelog5,cn=config
On the other hand, we do have cn=changelog,cn=ldbm database,cn=plugins,cn=config
with
nsslapd-directory: /var/lib/dirsrv/slapd-INST/db/changelog
/var/lib/dirsrc/slapd-INST/db/userroot/replication_changelog.db <=== in
1.4.4 we moved the global replication changelog into a database file for
each backend.
If you don't see these, then there is nothing to clean up.
I do have this directory: /var/lib/dirsrv/slapd-INST/db/changelog
Should I remove that whole directory?
No, that is the retro changelog database. There is no need to remove it.
So I suspect the downgrade to 1.4.3 screwed everything up. So sounds
like you need to simply recreate the replication changelog (if you are
are staying on 1.4.3), please follow the instructions from this link:
https://access.redhat.com/documentation/en-us/red_hat_directory_server/10/html/administration_guide/managing_replication-configuring-replication-cmd#Configuring-Replication-Suppliers-cmd
I don't feel comfortable to execute the commands in this document. If there are no "simpler" methods then I will probably re-install the replica. In any event, I want to be very careful before I take the next step.
Just to be safe, it might be a good idea to restart the server after
adding the replication changelog config entry.
HTH,
Mark
Start the server, and reinit the agreements on this server
That should do it.
Mark
But now I have a replication problem. Could this have been caused by
the update to 1.4.4.17 ? And, if yes, how can I fix this?
