Re: [Linux-cluster] GFS and samba problem, again



Hi Abhi,

Your mail astonished me. The only difference between your environment and our is that you've RHEL4 and we've Fedora 5 with GFS. I'm sorry about this but I have to insist. Are you completelly sure that your samba access was simoultaneous? because if you probe one client, and then another it isn't the same.
I found people that complain about the same problem we have:
http://www.redhat.com/archives/linux-cluster/2004-November/msg00065.html
http://www.centos.org/modules/newbb/viewtopic.php?topic_id=4997

Well, I had finally compiled GFS2 but I was uncapable to start cman daemons.
[root server2 ~]#  /etc/init.d/cman start
Starting cluster:
   Loading modules... done
   Mounting configfs... done
   Starting ccsd... done
   Starting cman... failed
/usr/sbin/cman_tool: aisexec daemon didn't start

And I obtain this when I try: # strace /usr/sbin/cman_tool -t 120 -w join
....
connect(5, {sa_family=AF_FILE, path="/var/run/cman_admin"}, 110) = -1 ENOENT (No such file or directory)
close(5)
write(2, "/usr/sbin/cman_tool: ", 21/usr/sbin/cman_tool: )   = 21
write(2, "aisexec daemon didn\'t start\n", 28aisexec daemon didn't start
) = 28
exit_group(1)

So I'm stalled by that way.

I'm downloading RHEL 30-days evaluating version and I'm also trying samba 3.0.23c compiling with cluster support.
I will tell you something as soon as I finish all test.
Regards,

Sandra

Hi Sandra,
I tried your test with 4 windows machines. 3 real machines and 1 simulated in vmware - all running windows xp home. Everything runs fine:
smbstatus on the samba server shows me this:

My smb.conf looks like this :
[public]
       comment         = ShareGFS
       path            = /public
       writeable       = No
       read only       = Yes
       write list      = @admsamba
       force group     = root
       create mask     = 0775
       directory mask  = 0775
       oplocks         = No
       locking = Yes
       strict locking = Yes

Also, since the share is readonly, there shouldn't be (m)any locks involved, which makes your problem seem all the more odd. Let me know if there's anything else I can try. Also, I'm curious about your test results with gfs2 and gfs1 from the RHEL4 branch.
