Making sure I remove the correct drive

Leave a Comment / DELL, Disks, File Systems, hardware, R730 / By /

Yesterday, I discovered I had removed the wrong drive from a zpool. In this post: FreeBSD 14.2 Today, the zpool replace command has completed. Next, I carefully chose the right drive to pull from the drive bays. Status This is the zpool status, just before it completed: After it completed: I see gpt/SG_ZHZ16KEX is no longer in the zpool. Not trusting myself, I checked this way: [20:33 r730-03 dvl ~] % zpool status […]

Yep, there it is. CTL-C, LED goes

But first, there’s more Right after asking “Anyone running zfsd? Did you do anything in particular to configure it? I just added my first hot-spare to a zpool.”, ivy told me “noooooooo don’t use hot spares!! Keep a cold spare or at least an online device not attached to a pool. otherwise your zpool will randomly decide to attach its hot spare due to a temporary cabling issue or something like that. the

Installing the replacement UPS

Leave a Comment / Eaton, UPS / By /

Around the end of last year, I started having trouble with my used Eaton 5PX – I’d had it for about 5 years and it was used when I bought it off eBay. On Saturday night (about 21:33:48 UTC), the home network disappeared off the Internet. I figured my new gateway had died. The dead UPS Sunday morning, I returned from the remote undisclosed location to the basement #homelab. Entering the basement, it

gw01 – setup photos – very little commentary

Leave a Comment / hardware, Qotom / By /

Earlier today, I installed FreeBSD 14.2 on gw01. EDIT: 2025-02-11: Yesterday, I found out the gateway draws 22W. And yes, as an Amazon Associate I earn from qualifying purchases. Here’s the link for that hardware. Here are some of the photos. The system is very quiet. I cannot hear it from 10 ft away. First boot – that first boot can take some time. 1-2 minutes. First boot trying the USB drive. Selecting

Three weeks ago, I tooted about getting a new gateway/route/firewall for the home lab. After many fantastic suggestions, I settled on a Atom-based solution in a 1U case. It’s the “Qotom 5X 2.5G LAN 2 SFP+ Barebone Mini Router Q20322G9 with C3558 1U Rackmount Mini Server” as sold on Amazon and shipped from China. The unit arrived 8 days after ordering. It could have been 7. It was out for delivery yesterday, but

Eaton 5PX removes power every 24 hours

Leave a Comment / Eaton, UPS / By /

When I powered on my UPS yesterday, I predicted when it would power off: 24 hours later. To be clear, it’s removing power from the outlets and not sending any notifications to the hosts that it’s about to do so. Today, I captured the console when resetting and trying to power on the UPS. The reset This is the reset output: At this point, I waited. With no more output for 3+ minutes,

Let’s find the dead cell in my Eaton 5PX

Leave a Comment / Eaton, UPS / By /

Todays goals: pull both the ups and the external battery unit (EBU). While there, swap them so the UPS is on top. Take photos of the wiring. Disconnect each battery. Measure it. Replace anything not like the others. Expecting 13V or so on most. One should read way less. Maybe. But the UPS is now charged to 100% All cells in the UPS measure about 13.4V. Next, the EBU. All aboutt 13.4 or

Complete network shutdown – wtf?

Leave a Comment / Eaton, General, nut, UPS / By /

This afternoon, I was running an Ansible script to update the snmpd configuration settings on nagios03 (which replaced nagios02 – which was intentionally destroyed earlier today). After the script completed, I could not access the ngaios3 website, nor could I ssh into the host. My first thoughts: I must have messed up the ssh configuration, I’ll fix it through the console. I can’t get to anything. Anywhere. WIFI now? No, it’s me that’s
