Reinitializing replica fails?

[Jonathan Kelley]

ipa-server-4.5.0-21.el7.centos.2.2.x86_64
ipa-server-common-4.5.0-21.el7.centos.2.2.noarch

​I was getting this error in errors.log:

​     ​
Data required to update replica has been purged
​     ​
from the changelog. If the error persists the replica
​     ​
must be reinitialized.

​This has been known to fix the issue:

[root@auth2 /]# ipa-replica-manage re-initialize --from auth1.mydomain.com
--verbose
ipa: ERROR: DNS query for auth1.mydomain.com. A failed: Text input is
malformed.
Traceback (most recent call last):

verify_host_resolvable
    raise errors.DNSResolverError(exception=ex)
DNSResolverError: Text input is malformed.
Unexpected error: Text input is malformed.

​I assumed I had a DNS issue, but can't seem to find one unless PTR records
are broken.

[root@auth2 /]# nslookup auth1.mydomain.com
Server: 127.0.0.1
Address: 127.0.0.1#53

Name: auth1.mydomain.com
Address: 192.168.0.33

[root@auth2 /]# dig auth1.mydomain.com @127.0.0.1

Do I just need to build a new replica and forget this one?​
