Multipath slow to create mapper files
We're running Oracle linux 5.9 and on one server within a 2 node Oracle RAC cluster, multipath mapper files take a whole 6 minutes after the local disk files to be created. The other server creates the files at the same time (or at worst a minute later) as the local disk.
Anyone have any ideas on this one?
Oracle support are telling me to put in a delay for Oracleasm so the files are created before the app starts (and after the mapper files are available) - this isn't a fix of course so I've rejected it.
