Samba with CTDB

[lazycy]

Hi, all
   I'm trying to setup cluster Samba on my own cluster filesystem these
days. I follow the process on http://ctdb.samba.org/configuring.html. After
finishing installation and configuration work, CTDB service seems run fine
on 2 machines:
[root at rpath-001 ~]# service ctdb status
Number of nodes:2
pnn:0 192.168.11.11    OK (THIS NODE)
pnn:1 192.168.11.12    OK
Generation:419290971
Size:2
hash:0 lmaster:0
hash:1 lmaster:1
Recovery mode:NORMAL (0)
Recovery master:0

  But when try to start samba, I got this error in my samba log file:

[2008/08/05 16:44:33, 1] lib/util_tdb.c:tdb_wrap_log(882)

  This error also happens if I try to add a user to samba, however, I doubt
that is there anything wrong with my ctdb configuration: below is my
/etc/sysconfig/ctdb: (others are just use default and I didn't use public ip
address)

CTDB_RECOVERY_LOCK=/mnt/share/recoverylock
CTDB_NODES=/etc/ctdb/nodes
CTDB_LOGFILE=/var/log/log.ctdb

Also, my smb.conf is as below:
[global]
        clustering = yes
        idmap backend = tdb2
        private dir = /mnt/share
        log file = /var/log/samba/log.smbd.%V
        passdb backend = tdbsam
        workgroup = WORKGROUP
        kernel oplocks = no
        syslog = no
        notify:inotify = no
[data]
        path = /xxx
        ................
Any suggestions or guides will be very helpful! 
Thanks,
Ethan
