I now have a Dell R7425 with 12 x 12TB HDD in the basement. A raidz2 zpool would give me about 120TB – with a significant resilver time. I have also thought about a creating 6 x mirrors and striping across them. That would give me about 72TB – that’s still a lot. However I do it, I’m going to label the partitions with the drive slot and serial number. I’m going to […]

Earlier today, I moved two file systems from one zpool to another. I use sysutils/sanoid to take and manage snapshots of the more important data. In this post, I’ll update that configuration. Migrating ZFS filesystems from one zpool to another – same host Migrating data02/freshports/dev-ingress01 to another zpool These are the items which need updates: [20:04 r730-01 dvl ~] % sudo cp -p /usr/local/etc/sanoid/sanoid.conf /usr/local/etc/sanoid/sanoid.conf.backup.2026.04.19 [20:08 r730-01 dvl ~] % sudoedit /usr/local/etc/sanoid/sanoid.conf [20:03

In a recent blog post, I showed you how I was taking my websites into maintenance mode. Shortly afterwards, I wrote about how using $server_name can have odd consequences. Today, I’m writing about the script I just created which will create those maintenance.html files. In this post: FreeBSD 15.0 nginx 1.28.2 bourne shell The script This is the script: Yes, the rm is not necessary, since the file has already been moved. To
I’ve updated one of my PostgreSQL instances to PostgreSQL 18, it’s time to update the others. This time, I’m going to try pg_update. My usual approach is pg_dump and pg_restore. As this is my first attempt doing this, I’m posting this mostly for future reference when I try this again. There will be another blog post when I try this again. Which should be soon. This paragraph will link to that post when

This post probably won’t help you much. It is mostly just me saving stuff I may want to refer to later. Also, this post covers only the initial hosts. It is the first step. I’ll also post it to my Mastodon toot. In this post: FreeBSD 14.3 poudriere-3.4.4 the FreeBSD ports tree on head as of 2026-01-20 I’m also moving from PostgreSQL 16 client to PostgreSQL 18 client Building Python 3.12 via poudriere

Now that r730-01 is booting from SATADOM devices (which are directly attached to the M/B, thereby freeing up drives bays / PCIe slots for larger devices), I thought it wise to buy a second pair. For two reasons: The price of used devices was pretty good It’s good to have spares nearby In this post: FreeBSD 14.3 smartmontools-7.5 smartctl info Here is the SMART info. Next drive: My notes The power on hours

Eight years ago, PostgreSQL introduced scram-sha-256 hashes for passwords. Eleven months ago, MD5 was deprecated. Yesterday, I got caught up with all this. Some of this post will deal with how I fixed it, but mostly it is documenting (for myself) what I did. The fix covers several services and takes place over multiple days. First, some background on why this change has come into focus for me. I have a FreeBSD jail

Following on from my previous post where I tested lz4, let’s try compression=zstd. Experimenting with compression off Experimenting with compression=lz4 Experimenting with compression=zstd – you are here Compression results First, we delete the old: [21:19 r730-01 dvl ~/tmp] % sudo zpool destroy Samsung-SSD-870-compression-lz4 [21:19 r730-01 dvl ~/tmp] % sudo zpool destroy Samsung-SSD-980-PRO-compression-lz4 [21:19 r730-01 dvl ~/tmp] % sudo zpool destroy Samsung-SSD-990-EVO-compression-lz4 Then create the new: [21:19 r730-01 dvl ~/tmp] % sudo zpool create

Yes, this is blatant bragging. But realistically, this is more a function of my ISP (Verizon FiOS) and my electricity supplier (PECO) than my abilities. To be fair, it is more contingent upon no power failures than anything else. I do have a UPS, but that’s only good for about 10-20 minutes. For August 2021, my home network had 100% uptime, according to RIPE. I’ve been hosting this device since 2013-05-29 (just over

I have some odd batteries in use at home. This post will enable me to look them up without opening up the device. Wireless light switch This is used in the server room (aka laundry room in the basement) Cable tester I have had this cable tester for many years. It’s an Ideal LinkMaster. It’s always done well by me. This what the cable tester looks like from the outside.
