[PATCH] Added --sync-all option to cobbler replicate which forces all systems, distros, profiles, repos and images to be synced without specifying each
1:15 p.m.
For your consideration:
Added --sync-all option to cobbler replicate which forces all systems,
distros, profiles, repos and images to be synced without specifying
each individually. I find this quite useful when trying to
completely mirror one cobbler installation to another backup machine
in a HA situation.

I don't think this will end up syncing any metadata across. I don't see
where it actually transfers anything. I would think you would have to
put in an else after the 'if not self.sync_all' that sets must include
on everything so that it gets synced across.
I'd also put in a --clobber to overwrite data on the local (slave) side
if you are doing this for a complete mirror. This would ignore the ctime
on entries and pull over the data regardless. That would cause cobblerd
to do more work, but ensure that you are an exact copy of the remote
(master) side.

Hey Scott -
Perhaps I missed it in my patch (let me verify), I'm doing the include
everything above (line 210) with a:
if self.sync_all:
for names in self.remote_dict[ot]:
self.must_include[ot][names] = 1

Looks like it made it. It's effectively adding everything to
must_include and setting them to 1 so it'll sync, or am I missing a
step?
I end up with this output from the cli (names changed to protect the innocent):

Yup, I missed it while looking at the patch. That looks
good. Applied. Thank you.

+1. This was in cobbler 1.6 if I remember rigt, not sure how/why it
got dropped.

Oversight. The entire replicate subsystem got an overhaul in 2.0. You
can do basically sync all by doing '--profiles "*" --systems
"*"'. But
it is nice to get an explicit sync all back in.
