Highly Available CIFS configuration problem

Oleg Podoukov — Fri, 18 Mar 2005 11:23:57 GMT

Hi,
I need to run CIFS 2.1.1 with ServiceGuard in active-active mode in two nodes cluster. I did all the configurations exactly the same as Admin's guide says. I've changed path from /var/opt/samba/locks default directory to /var/opt/samba/first_samba_node/locks directory in smb.conf.first_samba_node file ("lock directory =" parameter). But smbd and nmbd daemons (smbd -D -l /var/opt/samba/first_samba_node/logs -s /etc/opt/samba/smb.conf.first_samba_node) continue creating smbd.pid and nmbd.pid files to /var/opt/samba/locks directory. So, samba.cntl and samba.mon scripts doesn't work properly. Does anybody know the solution?

Thank you in advance,
Oleg

Servicegaurd has a log file. Please look at them and post the error text for help. Any time a monitor script fails the message is logged in a file in the /etc/cmcluster folder.

There may be useful information in the samba log, which is defined in smb.conf

Have you checked that you have changed your parameter in the smb.conf file.

lock dir = /var/opt/samba/first_samba_node/locks

pid directory = /var/opt/samba/first_samba_node/pids

How are these parameters set in your control file, too?
SMBD_PID_FILE=
NMBD_PID_FILE=

Thanks a lot, Roland! Addition of "pid directory =" to smb.conf.node_name files helped. Admin's guide tells nothing about this.
But there is another bug. After cluster started, there are one nmbd and two smbd daemons running:
root 10112 1 0 14:44:19 ? 0:00 nmbd -D -l /var/opt/samba/bird/l
ogs -s /etc/opt/samba/smb.conf.bird
root 10114 1 0 14:44:19 ? 0:00 smbd -D -l /var/opt/samba/bird/l
ogs -s /etc/opt/samba/smb.conf.bird
root 10122 10114 0 14:44:20 ? 0:00 smbd -D -l /var/opt/samba/bird/l
ogs -s /etc/opt/samba/smb.conf.bird

So, when I stop the cluster, one smbd stops, but the other doesn't.
Is this the normal behavior or something wrong with samba.cntl and samba.mon?

Sounds wrong to me - when samba shuts down - all daemons should stop....

What version cntl file are you using? (it is at the top - mine in A.11.09)

As I found out, this is normal behavior to have 2 smbd daemons (one is a child process). Cluster stops normally, no daemons stay running.
