[Freeipa-users] Exporting data?

[Bret Wortman]

My problems all seem to be with replication (see the threads with subjects
"Scorched earth" and "Replication woes"), and Rob has found an engineer
willing to look at log files for me. My problem is in getting the log files
over to you for analysis. The system I'm working with is on a private
network, so getting the logs off isn't trivial.

In my case I'm looking for a way to basically start over with as little
heartache as possible, and so far, after two weeks of trial and error,
we're no closer to being restarted than we were, well, two weeks ago. My
customer is getting antsy and I need to return our network to fully
operational within the next 24-48 hours or I'm going to have to nuke it and
start all over, which I know involves re-registering every single system
with the new master (because it'll be a new CA) and entering the new users
again, and setting up DNS over again. Which is why I was looking for a way
to export as much as possible right now so I can re-import in case the
worst happens and I have to nuke all my IPA servers and start over from
scratch.

I realize that no one can debug without logs and detailed information. It's
just taken a long time to get to where I am, and it takes a full 24 hours
or more for me to respond to any request for more detail.

In other words, I'm trying to leave my system as it is so we can try to
solve the problem it has and minimize the recovery effort, but I have to
balance that against my need to get my network operational again, and we're
having many, many problems with SSH, SSSD and other services since we don't
have a single IPA server in the mix that's fully functional right now. My
master is crippled with replication requests and the one good copy I made
couldn't get the CA transfer to work.

Frustrating for you because I can't always give quick data. Frustrating all
around. But we'll get through it one way or the other. I hope to have the
latest batch of logs over for analysis later this morning.
