Greetings,
We're running samba 3.0.21a with cups on debian to serve printing and
automatic driver download to XP clients.
I'm looking into setting up a Linux-HA printing system with heartbeat in
active/passive mode. Sorry, i'm new to this. From what I read, if a
failure is detected on one node the other will take over and startup
it's samba services.
My question is how do I keep the samba print queues,drivers, etc. synced
between the two machines?
Can I use NFS to store the samba installation and mount it on both
machines?
Or use rsync?
what files/directories need to be kept in sync?
much appreciated,
Ryan
That all depends on how you want to do it. You can share a SCSI array
and use a STONITH device to really kill the other node before mounting
it on the backup server. Or you can just keep things up to date with
regularly scheduled rsyncs. Or NFS. Since you only mention printing, I'd
recommend not using the shared SCSI and pick from either NFS or rsync. I
use rsync, because I don't need instant updates across both servers as I
only use samba as a print server.
As for the heartbeat stuff, I ended up just using the existing ethernet
connections for heartbeat transmission. I have a logical IP set up on
both machines for the samba service to use, and then I wrote a script
that a failed heartbeat calls when a node failure is detected that
brings up that interface and starts samba.
I can probably provide you with more technical details if need be.
