Installation and Upgrades / Zentyal High Availability using Pacemaker and Rsync
« on: February 23, 2011, 01:32:20 am »
So this one's a bit complicated:
I'm setting up 2 identical Zentyal boxes to run in HA. So far, I've got the bridge interface and Pacemaker working properly on both boxes.
The problem I have now is syncing the configuration. My first though was to use DRBD, but that doesn't appear to be an option because I can't use a DRBD volume as root and it doesn't look like Zentyal's configuration is stored in a single subdirectory (apparently Zentyal has config files in many places other than /home). Mounting an NFS share is not an option (defeats the purpose), so I was looking at rsync.
My question basically is: What do I rsync?

Is there any way to import information from an existing OpenLDAP server into Zentyal? I have an existing that I'd like to migrate.

Installation and Upgrades / Import/Export DNS Zones

Is there any way to import and export DNS information out of Zentyal? I have a pre-existing bind server and I would very much like to import the db files from bind.

Installation and Upgrades / Problem with X server, screensaver, and Alt-F7
« on: January 07, 2011, 09:20:09 pm »
I've got my copy of Zentyal 2.0-2 running, and everything appears to work just fine except...
When the screensaver kicks in, or the monitor is unplugged or goes to sleep, the user is kicked to a console prompt on F1. If I try to switch back using Alt-F7, the X session is apparently locked with a text display and some gibberish at the bottom, but reports as still running. I can't seem to kill it and I can't seem to start a new instance with startx.
It looks like the driver might be crashing when the screensaver kicks in for some reason, but I can't find this reported in logs anywhere.
Help on this would really be appreciated.

Installation and Upgrades / Restore backup during install
« on: December 03, 2010, 11:28:47 pm »
So here's what I want to do:
I have a PXE/imaging server configured to remote install Zentyal onto hardware.
I want to be able to take an existing Zentyal install, backup the server configuration (not the data), and then push that configuration to new servers via PXE installation. Ideally, this process would be automated (i.e. the config is backed up nightly to the PXE server).
I have different solutions in place (drbd and iSCSI SAN storage) to deal with the data.
It looks like Zentyal uses duplicity to back up it's configs, but there doesn't seem to be a lot of documentation on what's in those configs. What I really need is a way to combine a Zentyal duplicity backup with a "fresh" Zentyal install.
So here are my questions:
Just to clarify, it looks like all the data is stored in /home. Is that accurate?
Is anything hardware-specific in a Zentyal backup?
Does anyone have any advice for combining a Zentyal backup with a Zentyal install?
