<td align="justify">Hi,<br>
<br>
I'm having an issue with file locking whist using lustre+ctdb+samba<br>
<br>
My Lustre Setup<br>
mds/mgs<br>
3 oss<br>
3 Clients each with ctdb and samba services running.<br>
<br>
All servers and clients running Centos 5 - Kernal 2.6.19-92<br>
All servers and clients with Lustre 1.6.6<br>
ctdb 3.0<br>
Samba 3.2.1<br>
<br>
CTDB Configuration:<br>
<br>
./configure --bindir=/usr/bin --sbindir=/usr/sbin --libdir=/usr/lib/ctdb<br>
<br>
/etc/sysconfig/ctdb<br>
<p class="MsoNormal" style=""><span
style="font-size: 10pt; font-family: "Courier New";">CTDB_RECOVERY_LOCK="/share/mnt/recovery"<o:p></o:p><br>

style="font-size: 10pt; font-family: "Courier New";" lang="EN-GB">192.168.3.200/24

SAMBA Configuration<br>
<p class="MsoNormal" style="">./configure --with-ctdb=/etc/ctdb
--with-cluster-support --enable-pie=no --bindir=/usr/bin
--sbindir=/usr/sbin --libdir=/usr/lib/samba

comment = The Shared Area<br>
path = /mnt/lustre<br>
read only = No<br>
create mask = 0777<br>
directory mask = 0777<br>
<br>
All lustre clients have been mounted with the '-o flock' option.<br>
<br>
Everything from a linux prospective is working fine, my linux clients
can
read/write to files on the file share and file locking is active.<br>
<br>
>From a window share prospective clients can read/write to files on the
file share but file locking is not active.<br>
<br>
The only errors I can find from samba logs are:<br>
<br>
[2009/01/11 02:50:25, 3]
locking/locking.c:fetch_share_mode_unlocked(857)<br>
fill_share_mode_lock failed <br>

receive_message_or_smb failed: NT_STATUS_END_OF_FILE, exiting <br>
<br>
Has anyone dealt with a similar set-up and can assist with the file
locking from a ctdb+samba environment ? <br>
