[Samba] load balancing CIFS/Samba

[Barry Smoke]

I thought that at the moment this was impossible...thus we anticipate
using samba's msdfs support to spread out server load....putting
different shares on different servers, under one dfs tree...

Is this not possible in your situation?

between check if nmbd is running on foo1, foo2 and foo2
do diagnostic.txt all of them on each server

unless i misunderstand what you're suggesting, this does not work.

in DNS, foo = 192.168.1.1, .2, .3

192.168.1.1 = IP hostname foo1, samba server name foo1, share name bar
192.168.1.2 = IP hostname foo3, samba server name foo2, share name bar
192.168.1.3 = IP hostname foo4, samba server name foo3, share name bar

windows client does start->run->\\foo\bar
DNS returns 192.168.1.1
windows makes connection to 192.168.1.1 and asks for foo

>>>> windows asks for foo1 not foo, 
dns resolves foo to 192.168.1.1 which is smb server with foo1 name
you should be fine with architecture



which does not exist
failure

the only way i can make it work at all is to have the smb server name be

the same on all boxes.

does that make sense now?
