Re: [Samba] smb.conf sync
Hi, I already have a clustered config between my servers data partitions, is it possible to move my tdb files there and tell samba those tdb files are there? Is this meet the requirements of ctdb solution? I think I can give a try to syncronise my sysvol directory like this way, since the users and IDs should be identical. What are you think about this?

I solved the shared data problem with heartbeat+drbd combo so that should not be a problem. TDB files data should be syncronized between my domain members or am I wrong?

Re: [Samba] smb.conf sync
watch out when you do that!! i killed one of my previous test-setups by doing that when i forgot to change the netbios name for the second machine (so there were to DCs with the same netbios name, which totally blasted my setup. Even after shutting down all samba servers, stopping BIND, correcting the config, and trying to wipe the offending entries in the ._msdcs.blablabla zone, it kept spamming my logs every 5 secs about something (which i unfortunately dont remember now) so the simplest route was to reprovision. Lucky for me it was only a test setup :) Michael 2013/5/27 Sandbox sandbox...@gmail.com Hi, Just a quick question. Do I have to syncronise my smb.conf file between my servers?
