Well, it is good to hear that multipathing is working in some cases.
But, and I don't mean to troll or flame, just get my job done, it sounds
like if I want MP on the production database, I should stick with the
Red Hat this time around, eh?
Hopefully I can get some infrastructure to test on sometime. It would
be neat if MP on FreeBDS was very straightforward. It would be neater
still if I could make some small contribution to everyone elses' efforts
to make it happen. :)
