Reopen Issue

The nightly test test_integration/test_backup_and_restore.py::TestReplicaInstallAfterRestore::test_replica_install_after_restore failed in PR #147 - testing_master_389ds.
The test failed during replica installation, trying to communicate with PKI server on the master:

[ipatests.pytest_ipa.integration.host.Host.replica1.cmd30]   [5/29]: configuring certificate server instance
[ipatests.pytest_ipa.integration.host.Host.replica1.cmd30] Failed to configure CA instance: CalledProcessError(Command ['/usr/sbin/pkispawn', '-s', 'CA', '-f', '/tmp/tmpz1kefvsi'] returned non-zero exit status 1: 'WARNING : pkiparser      Unable to get security domain info: 503 Server Error: Service Unavailable for url: https://master.ipa.test:443/ca/rest/securityDomain/domainInfo\n')

The journal log on the master shows that PKI failed to start during the ipa-restore command:

Need to investigate how it is possible for ipa-restore to not detect the PKI start failure.

Are the full logs available anywhere?

The full IPA is started twice so having some idea which one failed could be useful (once as a start and once as a restart).

But it all happens in a big try/finally block so if a service failed to start then it should either raise an exception or have a non-zero returncode.

@rcritten
The logs are available there with the report

This makes my head hurt. ipactl in the restore shows that everything started just fine:

2020-02-29T21:15:03Z DEBUG args=['/usr/sbin/ipactl', 'start']
2020-02-29T21:17:26Z DEBUG Process finished, return code=0

Starting ipa-otpd Service
Starting ipa-dnskeysyncd Service

When in fact it failed and was reported properly by systemd:

So the ipautil.run to call systemctl start on the service should have blown up.

A typical startup would look like:

Starting pki-tomcatd Service
ipa: DEBUG: Starting external process
ipa: DEBUG: args=['/bin/systemctl', 'start', 'pki-tomcatd.target']
ipa: DEBUG: Process finished, return code=0

I think we should pass --debug to ipactl start in ipa-restore to get the full logging. I think that's all we can do for now since we can't otherwise see what happened.

Looking further into the logs it doesn't match the current code (even for ipa-4-8).

I wonder if this execution predates https://pagure.io/freeipa/issue/8226 so there is no call to ipactl restart. I wonder if that would have also addressed the pki issue.

It doesn't explain why nothing was raised though.

Lowering the priority as the issue is random and happens rarely.
