I like Postfix. I’ve been a fan of it for over 20 years. I deployed it on every host for outgoing email. Lately, I’ve taken to using dma (DragonFly Mail Agent) as my preferred mail handler on jails and hosts which don’t need to deal with incoming mail, only outgoing mail. After first getting serious with it about 6 months ago, I decided to remove it from all internal hosts during the consolidation […]

This is is mostly written after-the-fact without good notes. Much of what I’m writing is pulled from a tweet and from things I did as I later copied this VM from one host to another. In this post: FreeBSD 13.1 vm-bhyve-1.5. edk2-bhyve-g202202_1 qemu-7.2.0 Much of what I’m doing is based up David Reid’s blog post: Home Assistant on FreeBSD. I recommend reading his blog post and using updated values, perhaps from my post,

Now that I’ve filled up data01, I bought some more SSDs and created another zpool. Today, on this snow-is-anticipated Saturday winter morning, I’m going to move some ZFS filesystems/datasets around. Side note: I like the term dataset better than filesystem. man zfs talks about datasets, which can be a file system, a volume, a snapshot, or a bookmark. However, usually when I talk about a filesystem, it might be dataset. It’s a fine

I spent my lunch, and most of my mortgage payment, on 4 x 4TB Blue 4TB SSD 3D NAND (WDS400T2B0A).

Today I noticed that all the drives in the R730 host had 150MB/s speeds mentioned in the boot messages. They are all SSDs on an SAS bus. They should be at 600.000MB/s. The HBA in question is a AVAGO MegaRAID SAS FreeBSD (aka PERC H730P Mini). It can use either the mfi driver (default) or the mrsas driver (by setting hw.mfi.mrsas_enable=”1″ in /boot/loader.conf This is an SSD in a PCIe slot: This is

Over the past few days, I’ve posted a lot about transferring jails from two hosts into one host. One of the steps involves using zfs send | zfs recv to send the files from one host to another. I’m using syncoide for that transfer. A new fileystem’s recordsize defaults to 128K. In my case, that is usually OK, except for some specific datasets. For example: * video * backups * distfiles (tarballs) Here

I might need to create another zpool. Or perhaps move a drives/zpool from one host to another. In this post: FreeBSD 13.1 Background I am combining two hosts (slocum and r720-01) into one new host (r730-01). I have been moving jails from those hosts. I have an ansible playbook for creating new entries in /etc/jail.conf.d/. I thought I had the space calculations done right. Now I think I’m wrong.I’m already at 73% on

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

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.

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
