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



Hi Ahbi,

I've proved to install kernel 2.6.10 and GFS from cvs on Fedora 5 because if this software worked for RHES4 It will work also for Fedora. I have had to recompile the kernel and software, and have some problems because Fedora has gcc 4 and Red Hat gcc 3.4.6. Now I succesfully installed it but I'm getting odd errors with ccsd:

Nov 7 16:44:39 nocilla ccsd[15826]: Unable to connect to cluster infrastructure after 120 seconds. Nov 7 16:45:09 nocilla ccsd[15826]: Unable to connect to cluster infrastructure after 150 seconds. Nov 7 16:45:40 nocilla ccsd[15826]: Unable to connect to cluster infrastructure after 180 seconds. Nov 7 16:46:10 nocilla ccsd[15826]: Unable to connect to cluster infrastructure after 210 seconds. Nov 7 16:46:40 nocilla ccsd[15826]: Unable to connect to cluster infrastructure after 240 seconds. Nov 7 16:47:10 nocilla ccsd[15826]: Unable to connect to cluster infrastructure after 270 seconds. Nov 7 16:47:40 nocilla ccsd[15826]: Unable to connect to cluster infrastructure after 300 seconds. Nov 7 16:48:10 nocilla ccsd[15826]: Unable to connect to cluster infrastructure after 330 seconds. Nov 7 16:48:40 nocilla ccsd[15826]: Unable to connect to cluster infrastructure after 360 seconds.

cman starts ok and quorum is regained, but ccsd fails. I tried:
[root ~]# ccs_test connect
ccs_connect failed: Connection refused
[root ~]# ccs_test connect force
Force is set.
Connect successful.
 Connection descriptor = 60

Also I tried to start ccsd with -4 and -I parameters with the same results:
 #ccsd -4 -I 127.0.0.0.1

What could the problem be?
Thanks,

Sandra

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,
