pushed to RHEL54 branch http://git.fedorahosted.org/git/cluster.git?p=cluster.git;a=commitdiff;h=971ae8c3478df85910f65ea26dd29b37c7ad0a06
Technical note added. If any revisions are required, please edit the "Technical Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: When the clvmd lockspace got assigned the groupd id ZERO, dlm_controld rejected it.This caused the groupd to be blocked on systems with large amounts of scsi devices. With this update, id ZERO is not anymore assigned to clvmd. clvmd can now join the domain with a valid id and correctly interact with dlm_controld.
