I've tried to get OCFS2 1.4.1 with CTDB but no success. Maybe you give me idea what I did wrong. We have 2 nodes. Both nodes are running on Debian/Lenny. I've tried 2.6.26 and backported 2.6.29/2.6.30. The access to OCFS2 partition is by iscsi. The configuration file on both nodes: smb01:~#

Thank you Michael. I tried OCFS2. OCFS2 administration looks easier than GFS one. Yauheni Labko (Eugene Lobko) Junior System Administrator Chapdelaine Co. (212)208-9150 On Tuesday 11 August 2009 05:10:22 pm Michael Adam wrote: Yauheni Labko wrote: Thank you for the answer, Michael. As

Hi everybody, I have tested CTDB+GFS2+CMAN under Debian. It works good but I do not understand some points. It is possible to run the CTDB defining it under services section in cluster.conf but running it on the second node shuts down the process at the first one. My CTDB configuration implies

Hi, CTDB is pretty ignorant of CMAN as such. It just relies on a cluster file system, like GFS2. So you should only start ctdbd when the cluster is up and the gfs2 file system is mounted. I think you should not start ctdbd as a cluster service managed by cman, since ctdbd can be considered a

Thank you for the answer, Michael. As far as I understood clean_star=1 is absolutely ok for GFS/GFS2? CTDB is not going to work without Red Hat Cluster manage. CMAN starts dlm_controld and gfs_controld. ccsd handles node-to-node communication. I think GPFS has the similar manager like CMAN.
