Cannot override /etc/newsyslog.conf with /etc/newsyslog.conf.d/newsyslog.conf

Leave a Comment / FreeBSD, Open Source / By /

FreeBSD has a great concept of establishing default values and letting the user override them. That approach does not apply to newsyslog, and specifically, newsyslog.conf This idea came up on IRC after I said I was looking forward to a new FreeBSD 15 which allows the compression specified in newsyslog.conf to be overridden. Using /etc/newsyslog.conf.d Getting a clean copy First, I grabbed a pristine copy of /etc/newsyslog.conf from the repo: [12:34 r730-01 dvl […]

Finding out more about nvme on FreeBSD

Leave a Comment / FreeBSD, hardware, nvme, Open Source / By /

Recently I’ve been playing with NVMe to find out more about monitoring for wear. Tried nvme-cli: [17:49 r730-01 dvl ~] % nvme list Failed to scan topology: No such file or directory Seems it is a known problem. Went with this instead: [17:52 r730-01 dvl ~] % sudo nvmecontrol devlist nvme0: Samsung SSD 980 PRO with Heatsink 1TB nvme0ns1 (953869MB) nvme1: Samsung SSD 980 PRO with Heatsink 1TB nvme1ns1 (953869MB) With more information

I have a jail on r730-01 called dvl-ingress01. Here are some filesystems related to that jail: [11:50 r730-01 dvl ~] % zfs list | grep dvl-ingress01 | grep repos NAME USED AVAIL REFER MOUNTPOINT data02/freshports/dvl-ingress01/ingress/repos 8.65G 1011G 112K /jails/dvl-ingress01/var/db/ingress/repos data02/freshports/dvl-ingress01/ingress/repos/doc 706M 1011G 678M /jails/dvl-ingress01/var/db/ingress/repos/doc data02/freshports/dvl-ingress01/ingress/repos/ports 3.53G 1011G 2.30G /jails/dvl-ingress01/var/db/ingress/repos/ports data02/freshports/dvl-ingress01/ingress/repos/src 4.44G 1011G 2.73G /jails/dvl-ingress01/var/db/ingress/repos/src data02/freshports/dvl-ingress01/repos 120K 1011G 120K /jails/dvl-ingress01/var/db/ingress/repos That is not a complete list, but it illustrates the filesystems I’m working with

Updating a FreeBSD 14.2 host to FreeBSD 14.3 via freebsd-update

I’m ready to update r730-01 (I see that link is from 2024 – I’ll refresh it after this update) from FreeBSD 14.2 to FreeBSD 14.3.

Using a sparse git checkout to build vuxml files

2 Comments / FreeBSD, git, Open Source / By /

This post shows how I used a git spare checkout to build vuxml files without having the whole ports tree present. In this post: FreeBSD 14.2 FreeBSD 14.3-STABLE git-2.50.1 git-tiny-2.50.1 This came about when recent commits to security/vuxml weren’t showing up on in my host, despite doing pkg audit -F – this was several hours after the commit. trouble told me to check this jail on that host. Eventually I figured out the

x8dtu: adding in the smaller drive

Leave a Comment / Disks, File Systems, FreeBSD, hardware, Open Source, ZFS / By /

I was up at 5:30 AM today. I packed the car and headed out. I arrived within the datacenter at about 8:15 or so. By 8:50, I was on IRC and the photos of the FreeBSD racks were uploading. Since I was going there anyway, I did some inventory and disposal work (a decommissioned server, about 25 old HDD, and various bits and pieces). I must say though, I’m not liking this option.

Doing a bit of stress work on a new HDD

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

As foreshadowed in x8dtu – drive problems, I will be visiting a data center soon to replace a 4TB HDD. The replacement HDD arrived last night. It was unceremoniously tossed onto the front porch by the courier. However, it was properly packaged. I’m sure it’s fine. The original idea: put this drive into a host, and write some data to it, to exercise it a bit. As you will soon learn, that is

x8dtu – main ssds: how worn are they?

Leave a Comment / hardware, ZFS / By /

Let’s look at these two SSDs (full smartctl output appears at the end). pool: zroot state: ONLINE status: Some supported and requested features are not enabled on the pool. The pool can still be used, but some features are unavailable. action: Enable all features using ‘zpool upgrade’. Once this is done, the pool may no longer be accessible by software that does not support the features. See zpool-features(7) for details. scan: scrub repaired
