Using samba in a SG cluster

[Srinikalyan]

Hi,

HP-UX 11iv2
SG A.11.17
My requirement is to include samba in a Serviceguard failover package on a two node cluster node1(active) and node2(passive). I am going to use the samba toolkit(ECMT). In that I have read the Readme file. On that they have mentioned
[global]
workgroup = ha_domain
netbios name = smb1
interfaces = XXX.XXX.XXX.XXX/xxx.xxx.xxx.xxx
bind interfaces only = yes
I will be using the relocatable IP address in the interfaces field.
What is the significance of the netbios name here? Can I use any of the node names or package DNS name or any other name so that the CIFS client can access using this name?

Thanks,
Srini

Current system is the stand-alone server.
Current smb.conf looks like
[global]
netbios name = bcdmpa01
workgroup = LIVE_BILLIND
server string = BC Production server
wins support = no

The host name of this file contains is bclive01.

Shalom,

I have run samba in a two node SG cluster.

I used different netbios names during the test process to know which node was running.

Then I assigned a common netbios name to both smb.conf files.

It worked in both formats.

You are going to have to run some failover tests to see how your domain/DNS environment reacts. You may have to support the netbios name in each systems /etc/hosts networking environment to insure fast name resolution.

Thanks SEP.

Lets say I have a file look like below:

[global]
netbios name = tempname
workgroup = LIVE_BILLIND
interfaces = 10.24.128.31/10.24.128.0
server string = BC Production server
wins support = no
....
[live_log]
comment = Live1
path = /live1/log
browseable = yes
writeable = no
valid users = user1

How the CIFS client will connect to the CIFS server share. Is it just enough to use \\tempname\live_log?

Shalom again Srini,

I believe so. It is test time.

There comes a point where you take the configuration off the whiteboard and put it in production.

Do I need to specify the package DNS name i.e. tempname in the /etc/hosts file and windows hosts file like below for the CIFS clients to access the share?
10.24.128.31 tempname

smb.conf:
[global]
netbios name = tempname
workgroup = LIVE_BILLIND
interfaces = 10.24.128.31/10.24.128.0

Note: Requirement is in design stage so I need to confirm this method will work or not before doing the implementation and testing.

Thanks in advance,
Srini
