lvs-rrd protocol patch

I’m using lvs-rrd for a while. This set of script can easily generate nice graphs from an IPVS load-balancer. But the current scripts do not support traffic balanced on a same port with different protocols (ex: TCP/3000 & UDP/3000). I quickly wrote a patch to support multiple protocols: graph-lvs.sh.diff lvs.rrd.update.diff

Cluster on demand!

OpenSSI first true experience

A few months ago, I installed at work a Linux cluster based on OpenSSI. After looking for a free high-availability solution, this one seemed to be the best one, maybe due to my TruCluster experience. OpenSSI shares same features: single root filesystem process switching CDSL IP load-balancing and more… Lot
