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



Hello,

I've installed RHES4 evaluation version with kernel 2.6.10 and GFS from CVS. In this environment with same samba configuration as Fedora, We've opened one file simultaneouslly from 14 PCs and it works fine. I've proved with 2.6.10 kernel because Red Hat came with 2.6.9 kernel, but I wasn't able to compile with it, so I've probed next version.

I will try to copy same kernel+GFS and compile it in Fedora 5 to see if it works too.
Thanks,

Sandra Hernàndez

Hi Sandra,

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'll get FC5 installed on a test cluster and try it out.

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

Yes, the access was simultaneous. If you have a specific test, (specific types of files or windows programs) I can try that too. I'm not denying that you're seeing problems with GFS+samba :-). If I can reproduce your problem, I can chase it down and we'll know why this is happening.

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.

Looks like the openais component of the cluster is missing. The cluster architecture has changed quite a bit for GFS2. Please refer to this for help installing GFS2: http://sources.redhat.com/cgi-bin/cvsweb.cgi/cluster/doc/usage.txt?rev=1.35&content-type=text/x-cvsweb-markup&cvsroot=cluster

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

Thanks,
