I mean the CRM feature that is called "clones". See CRM documentation. > > - resource supporting active-active configuration; do you mean like > Apache instances in 2 resource groups configured to use different IP > addresses so they would not conflict? I mean that Apache should have a shared filesystem underneath it or some kind of another mechanism that will make sure that both instances have the same content. Also if you try to make an active-active filesystem you have to make sure that it support concurrent access on different nodes, i.e. you have to use something like OCFS2 or so. > > Regards, > mk > > >> >> On Mon, Jun 15, 2009 at 10:16 AM, Marcin Krol<[email protected]> wrote: >>> Hello, >>> >>> Let the newbie ask another question: >>> >>> Can both nodes in active-active configuration run the same *type* of >>> resources?
