Moving local settings for pg_hba.conf and postgresql.conf out of PGDATA

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

One of the configuration aspects of FreeBSD I have long liked is the concept of default values which are overridden by the user. For example, /etc/defaults/rc.conf (see The /etc directory). The default values in this file can be overridden by the user with their preferred values in /etc/rc.conf (or /etc/rc.conf.local, and other locations if you so choose (search for rc_conf_files)). With that approach in mind, I wanted to do the same thing with […]

Adding another pair of drives to a zpool mirror on FreeBSD

1 Comment / DELL, Disks, FreeBSD, General, hardware, Open Source, R730 / By /

Today, I’m ready to adding two recently obtained 12T spinning disks to r730-03. This host is the work-horse which houses all the main backups and database regression testing. It also hosts my newly-created but not yet-functional graylog jail. I will be following a previous post about adding drives because I don’t want to remember these things. They occur infrequently enough that documenting it is a good idea. In this post: FreeBSD 14 The

Clearing out multiple drives – while watching Band of Brothers

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

The accomplished reader will first ask, how is this post any different from Clearing-out multiple drives concurrently – while Watching Fargo Season 5? Well, first, it’s a different server. This one is r720-01. Second, I’m watching Band of Brothers, which is completely different. However, the approach is the same: Boot the host using an mfsBSD thumb drive ssh in as root wipe the drives watch Band of Brothers profit What’s not to like?

Configuration for running poudriere in a jail on FreeBSD 14

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

I run poudriere in a jail on FreeBSD – it really is becoming the thing-to-do with all the cool kids. Everyone’s doing it. It is nifty. I will provide only the jail configuration, and not any file system configuration. That is left for you. I think these links might be most helpful: Using poudriere to create a custom FreeBSD repository for package installation Moving poudriere from the host into a jail In this

Clearing-out multiple drives concurrently – while Watching Fargo Season 5

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

It is time to let the knew server go. It has gone through multiple upgrades, new drives, new boards, and new chassis. It has been replaced by r730-03. Before I let it go, I want to clear off the drives. By that I mean: I did this by booting the host using mfBSD (a lovely USB-bootable version of FreeBSD). I then ssh‘d in as root (one of the few situations when ssh as

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
