Re: [RDD] KPTZ is Finally Moving to 2.1.2
If it were me, I'd build a standalone Rivendell system with a copy of the database and all the audio files and put it on the air before taking everything down. That way, if things don't go according to plan, you can run the station from the standalone system for as long as you need.

In general, I try to plan for something that should take 30 minutes. With 30 minutes in mind, I have a backup good for 24 hours minimum, perhaps with manual intervention, but a l - o - n - g time regardless. Because, you never know. Whatever can go wrong, will go wrong. Best case, my 30 minute plan takes 15 minutes, and the backup is completely unnecessary. Worst case, at least the listeners don't notice. My last major automation move took 32 hours without a break, mostly due to someone else's poor planning.

[RDD] KPTZ is Finally Moving to 2.1.2
I'm looking for best practices from the group. Our current configuration; 1 - Server with separate root and /var/snd drives. 3 - Clients with sound cards and small (60GB) SATA II AV drives. They are all running the RRAbuntu LiveCD distribution. All the client machines are dual core 64 bit machines with 2 GB of RAM. The server is a dual core 64 bit with 8GB of RAM with enterprise class SATA III drives. We're doing this move this Saturday. I've got an 8 hour (is that enough time?) program block wav file I'm going to play out of our studio utility computer while the automation system is down. I've got new drives for all the computers. We're moving to the Broadcast Appliance distribution. Here's what I plan; 0) Shutdown all the clients and install new drives. 1) Rsync the new /var/snd drive from the old /var/snd drive before the old server is shut down. 2) Backup the Rivendell database. 3) Shut down MySQL and copy the database file(s) to a thumb drive. (Is the RDAdmin database backup enough?) At this point the plan gets a little tenuous. 4) Install the new root drive in the server. 5) Install the Broadcast Appliance CD in the server. 6) Install the /var/snd drive in the server. Change the mounts to point /var/snd to the new drive. 7) Copy the backup database file onto the system and restore it in RDAdmin. 8) Set up the NFS exports for /var/snd. 9) Install the Broadcast Appliance CD on all the clients on their new drives. 10) NFS mount the /var/snd from the server. 11) Change the client database configuration to point to the server database. 12) Shutdown MySQL in the clients and disable it. 13) Add all the clients in as hosts (not sure if this gets done in the db restore) 14) Configure the audio cards for all the clients. 15) Take the rest of the day off. Any holes? Ideas? Here's one... Our /var/snd file system is getting kind of big (almost too big to fit in a single enterprise class SATA drive). I'd like to install ZFS for the /var/snd volume. Anyone have any experience with ZFS on Centos 5.5? I've used ZFS on Solaris, BSD and Ubuntu but never tried it on Centos and I don't have the time before Saturday to experiment.
