That tells you that the locks are correctly stored in CTDB and
smbstatus can find them.  This means that smbd should be able to find
them too.

I can't help but think that smbd is somehow using different
configuration than smbstatus.

You don't have smbd/smbstatus installed from a package in /usr/ and the
other left over in /usr/local/, or similar?  In that case, they could
be getting their configurations from different places...

peace & happiness,
martin

Hi Martin,

No, nothing like that. Installing the Sernet packages obsoletes the
distro ones.

FYI:

# smbstatus -V
Version 4.4.6-SerNet-RedHat-31.el7
# smbd -V
Version 4.4.6-SerNet-RedHat-31.el7

# find /usr -name smbd
/usr/sbin/smbd
# find /usr -name smbstatus
/usr/bin/smbstatus

Thanks very much,

Alex

Interestingly I have a setup here for testing for rollout of S4 AD. The 
file servers are in an AD domain and are running Sernet 4.4.5, so one 
version older than production. I have tested the locking on these and it 
works. The only difference I can find that in prod, 
/etc/default/sernet-samba-ctdb contains these lines:

CTDB_MANAGES_SAMBA=yes
CTDB_MANAGES_WINBIND=yes

Whereas in the test environment they are:
CTDB_SERVICE_WINBIND="sernet-samba-winbindd"
CTDB_SERVICE_SMB="sernet-samba-smbd"

I'm wondering if this is what's making the difference?

Cheers,

Alex
