Hey Keep me posted (if you would) about how your setup works. (Sounds like you may have the time to test soon. Me, it will be 1st of Apr at the soonest) If by some miracle I get to work on it I will describe the entire process to let you know of any pitfalls.
I have studied this a bit, and am following the list (as well as Linux Virtual Machine cluster's list) I'd be glad to toss around ideas as I am banking on this along with heartbeat saving me any downtime -- otherwise I'm off to the tried-and-true (albeit slow cron+scp method and pray). The thing I am looking out for is what to do if one does go down. How can I get the raid-1 to sync back up right. ----- Original Message ----- From: "Alvin Oga" <[EMAIL PROTECTED]> To: "Kevin Long" <[EMAIL PROTECTED]> Cc: <debian-user@lists.debian.org> Sent: Thursday, March 22, 2001 6:32 PM Subject: Re: Beowulf cluster (was: parallel clusters of single cpu boxes) > > hi kevin... > > wow... cool... haven't seen or heard of nbd...but.... > if it does the trick.... humm maybe the time is here for > cheap-easily accessible clusters for high volume web/email servers ?? > > -- only problem now is time to spend to build up the clusters > and pull the (ethernet or power0 plugs on a few boxes and see if it > keeps working... > > thanx > alvin > http://www.linux-1U.net .... > > > On Thu, 22 Mar 2001, Kevin Long wrote: > > > > > ----- Original Message ----- > > From: "Alvin Oga" <[EMAIL PROTECTED]> > > To: "Darryl Röthering" <[EMAIL PROTECTED]> > > Cc: <debian-user@lists.debian.org> > > Sent: Wednesday, March 21, 2001 1:29 AM > > Subject: Re: Beowulf cluster (was: parallel clusters of single cpu boxes) > > > > > - am insterested too in... > > > - if system21 fails...( simulate it with pull the power plug ) > > > what happens.. > > > > > > - how to keep "data syncrhonized" on the cluster > > > > I am looking into the same thing.
