Cleaning up snapshots

Leave a Comment / FreeBSD, Open Source, ZFS / By /

Now that I’ve copied two filesets from one zpool to another, let’s delete old snapshots. In this post: FreeBSD 15.0 Freeing up space I’m still hesitant to delete original data, but I’ll delete the snapshots. Here’s my list: [20:25 r730-01 dvl ~] % zfs list -H -o name -r -t snapshot data02/freshports/dev-ingress01.DELETE.ME.after.2026.05.15 | grep -v for.data04.0 | less data02/freshports/dev-ingress01.DELETE.ME.after.2026.05.15/dvl-src@autosnap_2026-04-15_00:00:03_daily data02/freshports/dev-ingress01.DELETE.ME.after.2026.05.15/dvl-src@autosnap_2026-04-16_00:00:16_daily data02/freshports/dev-ingress01.DELETE.ME.after.2026.05.15/dvl-src@autosnap_2026-04-17_00:00:07_daily data02/freshports/dev-ingress01.DELETE.ME.after.2026.05.15/dvl-src@autosnap_2026-04-17_19:00:02_hourly data02/freshports/dev-ingress01.DELETE.ME.after.2026.05.15/dvl-src@autosnap_2026-04-17_20:00:02_hourly data02/freshports/dev-ingress01.DELETE.ME.after.2026.05.15/dvl-src@autosnap_2026-04-17_21:00:09_hourly data02/freshports/dev-ingress01.DELETE.ME.after.2026.05.15/dvl-src@autosnap_2026-04-17_22:00:09_hourly data02/freshports/dev-ingress01.DELETE.ME.after.2026.05.15/dvl-src@autosnap_2026-04-17_23:00:11_hourly … data02/freshports/dev-ingress01.DELETE.ME.after.2026.05.15/scripts@autosnap_2026-04-19_19:15:13_frequently data02/freshports/dev-ingress01.DELETE.ME.after.2026.05.15/scripts@autosnap_2026-04-19_19:30:02_frequently data02/freshports/dev-ingress01.DELETE.ME.after.2026.05.15/scripts@autosnap_2026-04-19_19:45:11_frequently data02/freshports/dev-ingress01.DELETE.ME.after.2026.05.15/scripts@autosnap_2026-04-19_20:00:01_hourly data02/freshports/dev-ingress01.DELETE.ME.after.2026.05.15/scripts@autosnap_2026-04-19_20:00:01_frequently That […]

Migrating ZFS filesystems from one zpool to another – same host

Leave a Comment / FreeBSD, Open Source, ZFS / By /

Not so long ago, a disk space issue arose. I obtained some new drives (thank you to those who donated) and I consolidated some of the space. However, I had not yet taken care of the problem. For my first example, I’ll copy my vm data over. In my next post, I’ll copy dev.freshports.org to a new dataset. In this post: FreeBSD 15.0 What happened? Yesterday, the chickens came home to roost.

Hacking openvpn to use syslog with something other than facility = daemon

Leave a Comment / FreeBSD, Open Source, OpenVPN / By /

I don’t see a way to specify the syslog facility for OpenVPN – perhaps I can change that in the code. It would allow logging openvpn to a specific file and being able to rotate that log file. –log-append does not allow for log rotation. In this post: FreeBSD 15.0 OpenVPN 2.6.19 Signals sent to OpenVPN do not affect logging. Thus, I must rely upon syslog and newsyslog to achieve log rotation. At

Script to generate that maintenance.html file for taking my websites into maintenance mode

Leave a Comment / FreeBSD, General, nginx, Open Source / By /

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

Using variable names in nginx declarations has a price: e.g. ssl_certificate /usr/local/etc/ssl/${server_name}.fullchain.cer;

I recently implemented a fun (to me) and easy solution for taking my web proxy websites offline, either one-by-one, or all-at-once. Today’s post talks about some of the repercussions which followed one-new-thing I tried. In this post: FreeBSD 15.0 nginx 1.28.2 I jump between testing the test host and stage host; both had similar issues. The relevant changes This is the type of change I started to do.

ddclient 4 changes

After a 4-hour power outage today (crews were working on the power lines), my home IP address changed, perhaps for the first time in over a year. I also noticed ddclient was no longer installed on my host. This blog post outlines changes from the original article.
