Not sure why I didn’t post this before, but here it is. When installing Nutanix CE on a Dell server (R710 in my case) with a PERC H700 card you can’t do a pass-through on the disks. You have to configure them as a single disk RAID0 in the PERC config. Ctrl-R at boot for […]
Since my last post I’ve been fighting to get the cluster back to some semblance of stability. Doesn’t look like that’s going to happen. However, there isn’t anything out there that approaches the ease of configuration, fault tolerance and hyperconverged storage I’m looking for. So…I’m making sure I have a backup copy of my VMs […]
I’ve had a number of problems with CE lately that look like they’ll be difficult to fix. Not sure I’ll have a better experience with a different platform, but I figure it’s about time to try. If nothing else, I’ll have some backup copies of my VMs, which is not an obvious thing in CE. […]
I’ve wanted to use simple Chromecast dongles for pumping a Grafana dashboard to a TV for a while now. The challenge has been how to effectively manage the casting source. Chromecasts can’t manage any of their own content, they can only be a casting target. I don’t want a mobile device sitting in the rack […]
Quick note about how to make this work. If you want to have two Unifi Security Gateways connect to a single controller at one location, you need to open up a couple of ports. Specifically, 8080 and 8443 need to be open to the controller. I strongly suggest you make sure you have a fixed […]
Just a reference for anyone trying to create a trunk between Dell and Ubiquiti switches. In my case, I wanted to create a trunk between a Dell N2048P and a Ubiquiti Edge Switch, with a native VLAN in use across the trunk. They both seem to have the notion of Access, General, and Trunk modes. […]
There seems to be conflicting info out there for how to accomplish this. Compounded with the Zero’s different micro ports, it’s easier if you can set it up as a headless device. Unfortunately, I found that if you try to do this locally, with a monitor and keyboard, the order of operations causes the ssh […]
With all of this tutorial publishing I’ve been doing for Grafana, I have neglected to post what mine currently looks like. So, here it is. This is the 1080P version. I also built an iPad version that has a lot of the same info but compressed for the smaller screen.
This is kind of goofy with how Ubiquiti doesn’t do well at supporting SNMP. For one thing, they don’t support it through the controller, only directly to each AP. But, you have to enable it at the controller to have it flip the switch on the APs so they’ll respond. They really want you to […]
Continuing the documentation effort. This is a shell script you run from Unraid in a cron job to feed stats to InfluxDB. You can then present them in Grafana. Note about that, I was having a lot of trouble getting the Grafana graphs to present correctly for anything coming from this script. I had to […]
