I’ve been seeing these types of errors for about 4 weeks now. I ordered a replacement drive. When it arrived, I realized I had no free drive bays. When a drive is still functional, I prefer to leave it in the host to retain zpool integrity. Instead, I will add the new drive in, run

Three weeks ago, I wrote about Replacing batteries Eaton 5PX – 5PX2200RT & 5PXEBM48RT. Back then, I did not properly replace the front panel before connecting the battery… Fixing this requires disconnecting the battery from the UPS. I’m not sure if I can do that live, but I’m not going to try. During this procedure,

This morning, I saw this in my logs: In this post: FreeBSD 14.1 r730-03 Looking in he logs, there wasn’t much useful: Searching online, I found swap_pager: cannot allocate bio so I decided to limit ARC size. I’ve done this before, and recently too.. Here is what I added to /boot/loader.conf: I just picked the

This post is mostly for myself. I’m just putting my Sunday morning thoughts down for later review and consideration. When Selecting replacements batteries for my Eaton 5PX UPS (5PX2200RT & 5PXEBM48RT), I began to think about: when the power goes off, why can’t I keep using my laptop? Usually, I still have an Internet connection:

Both nut and Nagios are telling me: replace my batteries. Fair enough. The UPS (5PX2200RT) and the external battery pack (5PXEBM48RT) were installed and configured with nut four years and two months ago. It’s time. Usually, I buy compatible third party batteries. Looking at video and images, I’m seeing these units use batteries in a

Sometimes you want to go back to a known good state. And you want to do it quickly, without waiting around. In my case, that’s going to be a zfs snapshot. Today I am preparing to test some code changes so that FreshPorts properly creates a new category. See these recent blog posts for details:
Let’s talk about zfs hold. Based on man zfs-hold: “If a hold exists on a snapshot, attempts to destroy that snapshot by using the zfs destroy command return EBUSY.” Let’s apply that to some FreshPorts snapshots which I don’t want going away: This is your typical FreshPorts website: [15:03 dvl-nginx01 dvl ~] % zfs list

see https://lists.freebsd.org/archives/freebsd-questions/2024-October/005877.html for the full archive. A while back, I changed my FreeBSD jails from using postfix to using dma. I like postfix, but I don’t want to maintain the app in so many locations. dma is less work. I wrote a short blog post about configuring dma and also blogged about replacing postfix with
