My Unifi US-16-XG switch was offline. It was still functioning correctly, but it was not in contact with the Controller. I wasn’t sure how to fix this, but this blog post shows what I now think should always work. It consists of two steps: Get the switch talking to the Controller Make the above change […]

I have two Unifi WAPs at home. I’ve installed them at three other locations. They are a great product. One problem I had was getting the management interface set. By that, I mean the IP address of the unit. I wanted it to be in a specific range, and therefore it had to be in

I’m writing this down so I can find it later. The management IP address on my Unifi US-16-XG is wrong. I’m going to change it via a combination of the controller and the CLI. Let’s hope this works. Hope? Why hope? Unifi switches are designed to be managed via the webgui (i.e. their controller). I’m

I’ve been given a Dell PowerEdge 710. I’ve installed two 30GB SSDs, installed FreeBSD 11 on them, and added four 500 GB SSDs. It will become a tape library server, replacing the R610 which will no longer be used. Some of the hardware came from the R610. The zpools: The filesystems: And dmesg:
I recently installed 6 SSDs into an R710. In this post, I will describe what I did to the empty SSDs before I started using them. short test I ran a short test on each one of the drives. I already had smartctl. $ sudo smartctl -t short /dev/da0 smartctl 6.6 2017-11-05 r4594 [FreeBSD 11.1-RELEASE-p1

I’ve been having boot issues with a server containing 20 HDD, all behind HBAs. I have decided to start booting off SSDs. In that previous blog post, there was much speculation about where to mount the new drives, etc. In the meantime, I came up with a solution which did not involve magnets and used

For future reference, this is the knew server. It runs a few jails, including Bacula regression testing services. This recent post outlines the modifications so it boots off a mirror of SSDs. File systems Paritions zpools /var/run/dmesg.boot
