Mapping sensors output to physical drives in Linux
Whilst building out some new Grafana dashboards over the weekend I made the switch from InfluxDB to Promtheus node exporters for scraping metrics from Linux servers. But how do you marry up the drivetemp-scsi-0-10 value output from sensors to a physical disk?
Restricting ASRock Rack BMC to dedicated IPMI_LAN port only
During this process I came across a frustrating "bug" in the Asrock Rack BMC implementation. No matter the settings I gave the BMC it was getting two IP addresses. One on the IPMI_LAN port as expected in my management VLAN, and another on eth0 which is undesirable.
These desert vistas absolutely boggle my little mind. Most people come to Las Vegas for the brash, expensive and over the top spectacle. Indeed, it is fun for a night or two. But given the choice between a night in Vegas or another night on those dunes, there's simply no contest.
Configuring Traefik on Synology DSM7 using docker macvlans
Recent changes in DSM7 have made guaranteeing being able to free up ports 80/443 for use by traefik rather difficult. Using a combination of several advanced techniques with docker networking we can circumvent this requirement once and for all with the macvlan driver.
ASRock Rack E3C246D4U - The Perfect Media Server Motherboard?
The board only arrived today but I've gotten it working in a couple of hours exactly the way I wanted. It really is about as close to perfect as we're going to get in this space. Should you buy one? Yes, if you need it - you should!
