That sounds to me like it should work, but I assume you would have to make sure never to make any LVM changes while more than 1 node has access to the shared device(s). This solution assumes that each disk will be shared separately by each node, right? If you could stripe them together on whatever machine actually has access to the disks and then share the logical volume or whatever as a single block device, the nodes would not have to deal with LVM at all, I should think. They would just see one shared "disk", instead of 4. On a related note, are there any plans for "Cluster LVM" support for OCFS? From a brief look it seems Cluster LVM uses its own distributed lock manager, which is different from the one used by OCFS2. Would it be possible to use both DLMs at the same time? Does anyone know if CLVM or OCFS could be made to work with another DLM so that they could both use the same one? Am I talking nonsense? :) -- Michael Wood <[EMAIL PROTECTED]> _______________________________________________ Ocfs2-users mailing list Ocfs2-users@oss.oracle.com http://oss.oracle.com/mailman/listinfo/ocfs2-users
