Sven, as to dmesg: I know these infos only from dmesg. Sometimes I am surprised how many infos I am missing when I only look at /var/log/messages instead... I found all important ocfs2 messages in dmesg. May be other on your box, I have SLES only. Did you do the "o2cb configure" thing before mounting the filesystem? The "Could not create domain" sounds to me like a bit of misconfiguration. And the output of "/etc/init.d/o2cb status" should look like (depending on the values you gave at configure time): Driver for "configfs": Loaded Filesystem "configfs": Mounted Stack glue driver: Loaded Stack plugin "o2cb": Loaded Driver for "ocfs2_dlmfs": Loaded Filesystem "ocfs2_dlmfs": Mounted Checking O2CB cluster ocfs2: Online Heartbeat dead threshold = 61 Network idle timeout: 60000 Network keepalive delay: 10000 Network reconnect delay: 10000 Checking O2CB heartbeat: Active Maybe you have to "/etc/init.d/o2cb offline" and reconfigure? That helped for me (in 1 case out of my 15 nodes). After reconfiguration, you may mount again and see the results via dmesg (I do). This may be necessary when you hat o2cb online first and created the cluster afterwards. I found it necessary to first create the cluster config, then "o2cb configure", and then mounting. Can you see your cluster in ocfs2console? Is your /etc/ocfs2/cluster.conf correct? My man page for o2cb_ctl says "Users are not advised to use this program directly but instead use the O2CB init service and/or ocfs2console." I learned to obey such hints ;-) Regards, Werner -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.16 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org/ iEYEARECAAYFAk3uIkoACgkQk33Krq8b42NQBgCeK7TGnqvHoJ8loFlqcyhbIKiX XnkAniEQ7UU14vAmfw1RD20ew7W9Wglf =xZTa -----END PGP SIGNATURE----- _______________________________________________ Ocfs2-users mailing list Ocfs2-users@oss.oracle.com http://oss.oracle.com/mailman/listinfo/ocfs2-users
