Re: [CentOS] Startech USB21000S

I can't speak to the actual USB device mentioned, but I bought a couple of Startech PCIe gigabit cards a few months back to add an extra set of interfaces on a pacemaker cluster and those cards turned out to be absolute crap. They would tend to go numb at random times and eventually require a serv

Re: [CentOS] oops, or how to bring a datacenter router down with one setting

Bob, I'd suggest you do some more reading on the purpose behind bonding and bridging. It *sounds* like what you functionally need is to have a server with a single route upstream, not acting as a gateway, but where you want to be able to take a failure on one of the upstream network connections w

Although it was written in the context of Xen, you might also want to have a look at the netloop nloopbacks parameter as described in . On a Xen cluster with 3 physical interfaces per node I had to

I have no idea if this is the source of your problem (I wasn't using bonded interfaces), but it's sufficiently similar that you might want to try it. I had a lot of problems with the network stack on VMs, both under VMWare ESXi and Xen where the network would just go numb. After a lot of splunkin

I'd recommend that you look at bacula. I've used many backup systems (both commercial and open source) over the years and bacula is by far the best of them overall, is under active development, robust, scalable, and has optional commercial support if needed. For CentOS 5.x, there are not-the-most-
