[Samba] multiple smbd/nmbd on one machine

[Markus Schwindenhammer]

Hi everybody,

hope my question is not misplaced :)

I have an HA-Cluster (RHEL 4 update 3, Veritas Storage-Foundation  
4.1, samba Version 3.0.10-1.4E.9) an have to run 3 different smbd/ 
nmbd on one machine.

So my smb.conf looks different for each "service", and is also stored  
in a separate folder.

(Structure is:

/home/smb/domain/cfg/ ...   #config for domain-controlling
/home/smb/share/cfg/ ...      #config for normal shares
/home/smb/perv/cfg/ ...        #config for a pervasive database that  
uses samba

... means that at this place the smb.conf, smbpasswd, ./locking/ 
*.tdb, ./private/secrets.tdb is stored

That is the only way, I can move the config and *.tdb in case of an  
fail-over to another node (shared storage).
)

Nearly everything is running well. I can create profiles, files and  
folders, can move them, change them but I cannot delete them. I have  
also figured out, that it must be a problem with one file in ./ 
locking/, because:

This is a version of smb.conf where everything is working fine. But  
by taking "lock directory = /home/smb/domain/cfg/locking" in the  
config, I cannot delete the files/folders, only touch, move and so on...

But that is no solution, because by running 3 times smbd I do need 3  
different lock directories...

Oh, btw: This is one entry in log.$machinename

{BTW: Dear programmers, please change the logging, so that there is  
only one line per entry!!!! The way it is solved now, it is  
absolutely useless for using grep!}


Is it possible that the path to /locking/*.tdb is hardcoded?

Does anybody has an idea?  Thank you very much!

Yours
