When either dirsrv or krb5kdc is down, named service restart in

Rather only report a failure to restart the service and continue
with the upgrade as it does not need the named service running. Do
the same precaution for pki-ca service restart.

Shouldn't we note it failed and retry later ?
Is there a risk it will be down at the end of the upgrade process ?


Seems like an overkill to me. It would not certainly help in this
case, because
the processes that named requires are down. As Rob suggested, user
the IPA may be running in a lower run level for example, it that case
I think
we may not even try to restart the service.

Oh I guess I wasn't clear, I did not mean to try to restart the service
immediately or multiple times, I meant to make sure that if the service
was running when the *whole* update started to make sure it is still
running when the whole update finishes.

The scenario is:

1. ipa runnig
2. do upgrade
3. restart fails for some reason
4. update completes

now what I would like to make sure is that if the restart failed at 3 we
try a restart after 4 so that we try to get things up when all the
updates are done.

Makes sense ?

Sort of. To be able to do this, I think we would need to at first get a
list of all running services (as user may have purposefully shut down
some service), then run the upgrades and check that all services in this
list are still running at the end of the upgrade. If not, try to amend it.

While this looks useful-ish, I would rather keep the patch 350 simple as
we are close to the release and I do not want to get too wild.

Now when I am thinking about it, maybe we should only try to restart
if the
service is running - because otherwise it would be started later and the
changes that were done in scope of upgrade script would be applied.

Yes we should do a conditional restart only, and it is ok to proceeded
if it fails, we want to complete the upgrade process in any case, not
break out in the middle if at all possible.


Right, I will send an updated patch which restarts the named/pki-ca
service only if it is running.

ACK on this patch as-is. I think we have room for improvement/discussion. Can you open a RFE ticket to investigate any further work we might want to do?
