Ocfs2 devel - Jun 2013 - why oracle give up dlm by disk on ocfs2? because performance?

Hi all,
   I found ocfs1.0 use the Distributed lock manager by disk. on ocfs2 why give
up? because performance or other reason?

   Btw:
     on the ocfs1.0 why not use scsi-2/3 reservation to protect to update the
dlm sector data?

Thanks,
Jensen.

Hi Mark, sunil, jeff an Joel,
   Do you know why ? Thanks.

Jensen.
