This post documents the PDU settings so I know what is plugged in where and the delay they have on power up. pdu1 – before pdu1 – outlet 1 – r720-01 pdu1 – outlet 2 – knew pdu1 – outlet 3 – slocum pdu1 – outlet 7 – LTO4 tape library pdu1 – after pdu2 […]
Today I tested the shutdown but was mostly concerned by the startup. I wanted the hosts to start in a specific order. I lived tweeted it and that thread is the basis for this post. The UPS has three groups of outlets: primary group, group 1, group 2. Each group has a On Delay setting. […]
Following on from my recent nut setup, this is the second in a series of three posts. The next post will deal with adjusting startup and shutdown times to be sure everything proceeds as required. I want to test the host shutdown mechanism without: unplugging the UPS from the mains powering off the UPS without […]
I use Tarsnap for my critical data. Case in point, I use it to backup my Bacula database dump. I use Bacula to backup my hosts. The database in question keeps track of what was backed up, from what host, the file size, checksum, where that backup is now, and many other items. Losing this […]
It is time to replace my existing UPS with another one. I’m getting only 3 minutes of runtime with the existing batteries (and new batteries, after recalibration). It was suggested I buy an Eaton 5PX. I wasn’t convinced. This is the first of three articles about nut. The second is about testing the shutdown. The […]
Today I added a OpenVPN client to a recent laptop I acquired. It was for my mom, but COVID19 has prevented that trip. Sometimes a task is so rarely performed that the steps are unfamiliar or even unknown. This is what I had to do today. The client zip package I create with ssl-admin works […]
I’m not complaining. It’s just very amazing how much work a laptop does to start up. As soon as I can get a terminal session I start: [dan@air01:~] $ w 18:13 up 3 mins, 11 users, load averages: 164.29 42.91 15.80 USER TTY FROM LOGIN@ IDLE WHAT dan console – 31Dec19 230days – dan s000 […]
ZFS has a the ability to share itself within a jail. That gives the jail some autonomy, and I like that. I’ve written briefly about that, specifically for iocage. More recently, I started using a zfs snapshot for caching clearing. The purpose of this post is to document the existing configuration of the production FreshPorts […]
I encountered, and later solved, a DNS issue on a FreeBSD jail. The jail is my web proxy, of sorts. I have one public IP address, which is dynamic (not relevant, but mentioned only in passing) so all incoming web traffic goes to a single internal RFC-1918 IP address. From there, nginx does reverse proxies […]
Today was battery replacement day at my place. The UPS batteries were replaced without downtime. That doesn’t mean there wasn’t downtime. I am not documenting this in real-time. This is post-event analysis. First, I wanted to change the battery replacement date, so I ran acptest on the pfSense server, to which the UPS is connected […]
