Transferring a jail from one host to another

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

I’ve started merging these two hosts: r710-01 slocum into this one host: r740-01 The goal is to then retire those first two hosts. This post covers the initial bulk copy of all the data from two hosts into the one. In this post: FreeBSD 13.1 Each jail runs on its own zfs filesystem Not covered by this post Creating jails Creating snapshost Detailed usage of syncoid hosts not using zfs The overall process […]

Ansible playbook for FreeBSD jail.conf.d

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

While I was moving jails from one host to another, I decided to start using /etc/jail.conf.d/. The idea is each jail gets its own configuration file in that directory, instead of using /etc/jail.conf. In this post: FreeBSD 13.1 But first, you should know Let’s get some things out in the open before you jump into the change. The main advantage of /etc/jail.conf.d/ is each jail gets its own configuration file. Easy to find.

error: cannot open ‘.git/FETCH_HEAD’: No space left on device

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

After moving the poudriere jail (pkg01) to the new host (r730-01), I noticed this message from Nagios: That “email found in . /var/mail/dan” message is significant. In general mail on my hosts/jails is not delivered locally. It all goes off-host. That’s why I have this Nagios check. When mail like that is found, it’s either a configuration error or something local has gone wrong. In this post: FreeBSD 13.1 poudriere-3.3.7_1 NOTE: This is

Moving one jail from host to host

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

This is a quick post about the steps I’m using to move my jails from one host to another. This is bing done as I merge two hosts into one. I have not attempted to automate this, apart from the initial syncoid copying of data. This post is base roughly upon my Mastodon post from yesterday. In this post: FreeBSD 13.1 sanoid-2.1.0 copying from slocum copying to r730-01 use of /etc/jail.conf.d/ Right, now,

NOTE: If you’re looking for a jail configuration for poudriere, please refer to Configuration for running poudriere in a jail on FreeBSD 14. I recently moved the pkg01 jail from one host to another. I’m having trouble getting it to build packages.

Why doesn’t sysutils/vm-bhyve start my hosts?

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

After booting, my vms are not started by sysutils/vm-bhyve. Why? Perhaps it’s because I did not set vm_list. Here is me starting them today up after booting the host yesterday. NOTE: I already have a not to myself to add VM monitoring to Nagios.

How to limit a jail

1 Comment / FreeBSD, FreshPorts, rctl / By /

After encountering a rare instance where processing a FreeBSD commit caused FreshPorts to run low on resources, I want to investigate how limiting a jail might help this situation. I searched for ‘jail limit’ – found sentencing guidelines. I searched for ‘jail limit freebsd’ and found a FreeBSD Forums referring me to rctl(8), which I recognize from my $DAYJOB. I’ve just rebooted my host to add this to /boot/loader.conf: Then I started referring

Upgrading an NVMe zpool from 222G to 1TB drives

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

The FreshPorts dev, test, and stage websites are hosted on a server in my basement. Each instance consists of two jails: an ingress node – for pulling in new commits (and other data) into the database. a webserver node – for displaying the web pages. The new drives: Sometimes the zpool gets too close to full. I tweeted about one incident on March 2021. I held hope that some spare SSDs might be
