It’s time for me to get off MySQL 8.0. It is not my database of preference, PostgreSQL is, however, I’m moving to MySQL 8.4. In this post: FreeBSD 14.3 MySQL 8.0.44 MySQL 8.4.7 The plan This is my plan, as tooted: zfs snapshot data02/jails/mysql01@mysql80 zfs clone data02/jails/mysql01@mysql80 data02/jails/mysql02 Get that mounted (it mounts automagically) modify the /etc/rc.conf entries of the new jail disable mysql_server so it doesn’t start up add a /etc/jail.conf add […]

Migrating my hosts from Python 3.11 to Python 3.12

Leave a Comment / FreeBSD, General, pkg, poudriere / By /

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

Today I got this message in the logs: The rest of the message told me it was a cronjob run by the rsyncer user on my x8dtu host. Looking at that cronjob I found: [rsyncer@x8dtu ~]$ crontab -l # use /bin/sh to run commands, overriding the default set by cron SHELL=/bin/sh # mail any output to `dan’, no matter whose crontab this is MAILTO=dan@langille.org # take a local copy of the bacula stuff

Copying everything off a zpool, destroying it, creating a new one, and copying everything back

1 Comment / FreeBSD, Open Source, syncoid, ZFS / By /

I have a problem with a zpool. To be clear, this really isn’t a problem. I’m not aware of any I/O throttling etc. It is just something I would like to change. zpzpoo% [18:26 r720-02 dvl ~] % zpool status data01 pool: data01 state: ONLINE status: One or more devices are configured to use a non-native block size. Expect reduced performance. action: Replace affected devices with devices that support the configured block size,

data04: moving data01/bacula/volumes over

Leave a Comment / FreeBSD, ZFS / By /

After finally creating data04, it’s time to relocate some data. In this post: FreeBSD 14.3 The source The current zpool which is straining is data01: I plan to move data01/bacula/volumes over first, then data01/bacula/working. Let’s modify the source for better results on the move. What do we have now?

It’s time. Time to create the 8x 4T raidz2 zpool. These are the devices: disks=”nda0 nda1 nda2 nda3 nda5 nda8 da12 da13″ In this post: FreeBSD 14.3 Check for existing partitions Using the list above: [18:15 r730-01 dvl ~] % gpart show | grep -E “nda0|nda1|nda2|nda3|nda5|nda8|da12|da13” => 40 7814037088 nda5 GPT (3.6T) => 34 7814037101 nda8 GPT (3.6T) Note I could not do this command because it fails at the first error: [18:05

Making room to creating a raidz2 from 8x 4TB devices – here. we. go.

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

It’s time. Time to create the 8x 4T raidz2 zpool. That doesn’t happen in this post, hopefully the next one. But first, I have to move some stuff around, to free up all the 4TB devices. The host has 4 devices (NVMe) and I moved in two more, 4TB SSDs.

How to recover when booting to multiple zroots?

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

On Nov 28, I rebooted r730-01 after an update, and it didn’t come back. At all. I had inserted 2x 4TB SSDS a few days earlier. It seems they contained remnants of a zroot. The host was trying to boot from them. I couldn’t get the host to boot from the real zroot. It frustrated me. I gave up and went to sleep later. The next morning, I moved those two drives into

Creating a new zpool for r730-01

Finally, it’s time to put together a new zpool for r730-01 (the storage information at that URL is already out of date; once this new zpool is created, another post will replace it). In this post: FreeBSD 14.3 I just realized, that my previous post on the zpools for this host revealed there is already a zpool with 2x 4TB NVMe: data02: [20:17 r730-01 dvl ~] % zpool list data02 NAME SIZE ALLOC

prod – moving to a SATADOM based zpool (zroot) using zfs snapshot and send | recv

Leave a Comment / DELL, Disks, FreeBSD, Open Source, R730, ZFS / By /

In this post, I’m moving my zroot zpool from larger devices to smaller devices. Why? Well, the smaller devices happen to attach directly to the main board of my server, albeit with some slight modification to a fan cowl. There have been several recent posts regarding this topic. I tried a different zpool approach, where I added new devices to the zpool and removed the old devices. That worked. It wasn’t ideal for
