Re: [Freeipa-users] IPA Backup / Restore - Everyone's favourite problem child!
Hi, I have successfully restored IPA servers from an ldif...more times than I care to recall in the last 2 months. In fact at one stage I took an ldif from the replica and used it to restore the masterso it seems pretty robust. In terms of filling with water, depends on how long for but the physical parts of the hds ie platters and arms should survive that.electronics might as well.in which case swapping one half (I assume you have a raid1) to a new box and syncing it might workthen drop out the old disk and slot in a new one...same with fire / smoke damage. NB One of the recommended ways to put out a fire in a server room is water misting using de-mineralised water 1 to 4 looks OK to mesomething I want to fully try. There are some interesting tech like gluster which give you a distributed raid1Im wondering on using virtualisation and gluster together...IPA for your scenario would be very small 1 core and 2gbnot much disk useuse kvm and gluster might work well. The second machine could be a reasonable spec'd desktoplike <$2k should be good enough I have a single Esxi machine at home, when I get the chance and buy a second one then I want to try something along the above lines...the idea is to avoid having a NAS and that expenseso 2 ESXi boxes running a gluster node on each and then the rest of the VMware guests inside gluster's "disk".

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Howdy all We have had quite alot of discussions on the list about this process but I'd like to get some documentation together so we are all speaking the same language. So last night I wrote a script to backup IPA based on the below article. https://access.redhat.com/knowledge/solutions/67800 This is fine and dandy. I have an easy way where I end up with a config tarball, an LDIF export of Dogtag and an LDIF export of LDAP. Now my question is "how on earth am I meant to restore it? My test scenario is as follows. And you'll have to humour me a bit with my imagination. Background: Customer has a very small environment. Single IPA server installation on a physical server. Several member servers and clients all pointing to that one server for IPA / CA and DNS. Incident: A very unhappy employee has just been fired for being a naughty boy and decided, for revenge to test how water tight the server was by filling the chassis with 5 litres of water. Result: Server is no longer happy either. A new server deployment is required to replace old server. Thoughts for restoration: My thinking was, to build a replacement server with all dependency packages and then: 1. restore config files in order to start IPA services 2. restore LDAP ldif file to ensure LDAP data was correct 3. restore Dogtag ldig file to ensure Dogtag data was correct. 4. restart IPA services to bring things back online smoothly. Of course Steps 2-4 didn't happen as they DEFINITELY were not happy to co-operate. I'm trying to get to a stage, where we have a method or procedure for simple restoration.
