Our NFS server setup at our datacenter consists of two SuperMicro SC933 chassis, each with dual Intel Xeon 3 Ghz, 2GB memory, and 15 200GB SATA disks connected to a Areca ARC-1160 16-ports SATA RAID controller. High Availability by redundancy and fail-over is taken care of by Heartbeat and DRBD. This setup is responsible for serving up document roots for our web cluster through NFS, and it obviously is very important that it always works

These systems run Slackware Linux, which has historically been my distro of choice for critical systems. When deploying Heartbeat on Slackware i ran into some issues which i’d like to share here. I won’t go into basic stuff like actually compiling and installing DRBD and Heartbeat, since that is pretty well documented in various other places, for starters the Linux-HA site (home of Heartbeat).
