Hi,

I've setup two server A + B (debian etch) with drbd + heartbeat in
active/passive mode.  If the primary server A fails, the shared
storage is mounted on B, the virtual ip A-vip moves to the new primary
B and samba is started by heartbeat. This works well, but I'm not sure
which samba files should be identical on both server. Both have a
dedicated machine account at the moment.

primary:           A,     192.168.0.50 (active)
secondary:         B,     192.168.0.60 (passive)
cluster/failover:  A-vip, 192.168.0.70 (dns name and ip that the
                                        client use to access the
				        shares)

Should I just kick all samba files on B and sync them with the files
of the primary server A (maybe rsync or inotify, I don't use
drbdlinks....)?

I *think* this would be the necessary directories:

/etc/samba
/var/cache/samba
/var/lib/samba
/var/log/samba
/var/run/samba
/var/spool/samba

I've not set any host specific paramters in smb.conf, I use the
dns alias A-vip and the virtal-ip for the netbios alias and interface
settings.

BTW: the machine account was created for the hostname of the primary
server A, not the DNS alias A-vip, will this lead to a problem?

Ralf
