Creating a Time Capsule instance using Samba, FreeBSD, and ZFS (latest)

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

This is a rewrite of a previous post on the same subject. I have rewritten it because I created a new jail ™ and I’m using a different configuration now. I recently moved a Time Capsule instance from a FreeBSD host into a jail. Later, I moved to using Samba instead of AFP. Why? Samba seems to be the preferred solution because AFP has been deprecated. It still works, but let’s go Samba. […]

FreeBSD jailed ZFS datasets – how do I find the .zfs/snapshot directory?

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

On FreeBSD, you can jail a ZFS dataset – that is, the jail can manipulate the ZFS dataset as if it was a host (more or less). This has useful applications. In my case, I want to backup a snapshot of that dataset from the host. For example, I want to backup this dataset: [12:19 r730-01 dvl ~] % zfs list data02/freshports/jailed/dev-ingress01/data/latest_commits NAME USED AVAIL REFER MOUNTPOINT data02/freshports/jailed/dev-ingress01/data/latest_commits 572K 798G 120K /var/db/ingress/latest_commits Within

Debugging snmp output when using LibreNMS

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

Librenms is my tool-of-choice for grabbing metrics from switches, servers, wireless access points, and anything else with an snmp interface. In this post: FreeBSD 14.0 LibrenMS 23.11.0,1 – updated to 23.11.0_1,1 within this post net-snmp-5.9.1_4,1 After updating some hosts to FreeBSD 14, the zfs application/extension broke. It was quickly amended after a report was lodged. However, after the fix, I still wasn’t getting graphs. It was nan all across the board for ZFS:

ntpd[66134]: leapsecond file (‘/var/db/ntpd.leap-seconds.list’): will expire in less than 9 days

Leave a Comment / FreeBSD, ntpd, Open Source, Time sychronization / By /

If you’ve been watching your logs, you’ve probably noticed messages like this: In this post: FreeBSD 14.0 ntpd .2.8p16-a (included with the base OS) There are several FreeBSD PR lodged, the most relevant (to me) is ntpd: leap-seconds.list should not run inside jails, and IETF is no longer hosting it. The fix I am using: Tell ntpd to use this source for leap-seconds. [14:02 r730-01 dvl ~] % sudo sysrc ntp_leapfile_sources=https://hpiers.obspm.fr/iers/bul/bulc/ntp/leap-seconds.list ntp_leapfile_sources: https://cgit.freebsd.org/src/plain/contrib/tzdata/leap-seconds.list

Avoiding repetition within jail configurations

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

Without resorting to configuration tools, such as Ansible, I wonder if there is an easy way to avoid repeating a list of datasets within a jail configuration. First, some facts: FreeBSD 14.0 I use plain vanilla jails I know this can be easily scripted with a configuration tool; that is out of scope for this post I want to explicitly list the datasets; taking all the children of a given dataset is out

Post upgrade – checking the jails

Leave a Comment / FreeBSD, freebsd-update, Jails, Open Source / By /

Stuff goes wrong. I like to check. Trust. But. Verify. Skip to the end for the list of useful commands. Here’s some of that verification, as briefly mentioned in FreeBSD 14 upgrade – files not removed by delete-old and Excluding some jails from upgrade. After upgrading all the jails on r730-01, I wanted to make sure that all the binaries had been updated from FreeBSD 13. Here’s what I did. This tells me

Excluding some jails from upgrade

Leave a Comment / FreeBSD, Jails, mkjail, Open Source / By /

I have some jails already updated to FreeBSD 14 – let’s get a list of what needs to be updated. This cold just as easily be used to get a list of what not to upgrade, if you didn’t want to update all jails right now. These jails are already updated: [15:30 r730-01 dvl ~] % file /jails/*/bin/sh | grep 14 /jails/bacula/bin/sh: ELF 64-bit LSB pie executable, x86-64, version 1 (FreeBSD), dynamically linked,

FreeBSD 14 upgrade – files not removed by delete-old

I was upgrading a jail (dns1) on r730-01 and I noticed this output from mkjail: In this post: FreeBSD 13.2 (upgrading from) FreeBSD 14.0 (upgrading to) mkjail-0.0.4 (upgrading with) EDIT: 2023-12-05 : This happened again when I updated the tallboy host. Looking at the mkjail source, I realized it had just completed the pkg upgrade and delete-old steps. I manually ran the delete-old command: [14:01 r730-01 dvl ~/src/scripts] % sudo jexec dns1 make

Figuring out the upgrade path for AWS RDS from PostgreSQL 12.14 to PostgreSQL 16.1

Leave a Comment / AWS, FreshPorts, Open Source, PostgreSQL / By /

These are my notes on figuring out an upgrade path for the FreshPorts PostgreSQL 12.14 database hosted on Amazon RDS. Most of this is based on Upgrading the PostgreSQL DB engine for Amazon RDS The sections of this post relate to the sections found at the above URL. First, I installed the AWS CLI (via py39-awscli, created an Access Key for my AWS login, and ran: Note that on line 4 I did

Bacula: Moving from 9.x to 13.x and upgrading the PostgreSQL database

2 Comments / Bacula, FreeBSD, Open Source, PostgreSQL / By /

I have been using Bacula since 2004. It is my backup solution of choice, not only because it has a PostgreSQL backend, but it is flexible, robust, and reliable. I, on the other hand, have long ignored recent releases. I’m using Bacula 9.6.7 (released on 2021-01-26), roughly 3 years ago. Today, I started the upgrade to 13.0.1 (still not the latest release, but that’s because of a minor compile issue, not yet resolved;
