samba - Jun 2008 - CTDB problems: 1) Unable to get tcp info for CTDB_CONTROL_TCP_CLIENT, 2) ctdb disable doesn't failover

greetings,

trying to follow tridge's failover process at

   http://samba.org/~tridge/ctdb_movies/node_disable.html

I encounter this error.

oss02:~ # smbstatus  -np
Processing section "[homes]"
Processing section "[profiles]"
Processing section "[users]"
Processing section "[groups]"
Processing section "[local]"
Processing section "[i3]"
Unable to get tcp info for CTDB_CONTROL_TCP_CLIENT
db_open_ctdb: opened database 'sessionid.tdb' with dbid 0xc0bdde6a

Samba version 3.0.26pre1-SVN-build-UNKNOWN

That's odd but I can still run without -np and get some information

oss02:/ # smbstatus

But, when I disable the current node

oss02:~ # ctdb disable -n 1

oss02:/ # ctdb status
Number of nodes:3
pnn:0 10.200.20.55     OK
pnn:1 10.200.20.56     DISABLED (THIS NODE)
pnn:2 10.200.20.58     OK
Generation:643008338
Size:3
hash:0 lmaster:0
hash:1 lmaster:1
hash:2 lmaster:2
Recovery mode:NORMAL (0)
Recovery master:1

the files stop copying, the private interface goes down on node 1
and there is no failover.  Eventually, in the screen where I'm running
a copy loop, I see:

cp: cannot create regular file `ls.4190.exe': No such host or network path
`/bin/ls.exe' -> `ls.4191.exe'
cp: cannot create regular file `ls.4191.exe': No such host or network
path


If I reenable the node, the private interface comes up and the
files start copying again

oss02:~ # ctdb enable -n 1

`/bin/ls.exe' -> `ls.4539.exe'
`/bin/ls.exe' -> `ls.4540.exe'

My config is:

oss02:/ # perl -ne '/^#|^\s*$/ and next;print' /etc/sysconfig/ctdb
CTDB_RECOVERY_LOCK="/net/lmd01/space/ctdb.lock"
CTDB_PUBLIC_INTERFACE=eth3

Thanks for any help,
