Hi everyone,
I'm stuck with a broken replica. I had a setup with two ipa server in
replica (ipa-server-4.6.4 on CentOS 7.6), let's say "idc01" and
"idc02".
Due to heavy load idc01 crashed many times, and was not working anymore.
So I tried to redo the replica again. At first I tried to
"ipa-replica-manage re-initialize", with no success.
Now I'm trying to redo from scratch the replica setup: on idc02 I
removed the segments (ipa topologysegment-del, for both ca and domain
suffix), on idc01 I removed everything (ipa-server-install --uninstall),
then I joined domain (ipa-client-install), and everything is working so far.
When doing "ipa-replica-install" on idc01 I get:
[...]
[28/41]: setting up initial replication
Starting replication, please wait until this has completed.
Update in progress, 22 seconds elapsed
[ldap://idc02.my.dom.ain:389] reports: Update failed! Status: [Error
(-11) connection error: Unknown connection error (-11) - Total update
aborted]
And on idc02 (the working server), in
/var/log/dirsrv/slapd-MY-DOM-AIN/errors I find lines stating:

You may have to reinitialize the remote replica, or the local replica.
It seems that idc02 remembers something about the old replica.
Any hint?
Thank you in advance,
