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 …
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 …

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’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 …
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 …
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 …

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 …
I recently moved the pkg01 jail from one host to another. I’m having trouble getting it to build packages. [pkg01 dan ~] % sudo poudriere testport -j 131amd64 -p dvl -z primary -i devel/py-pip [00:00:00] Error: Please load the linux module on the host using “kldload linux” On the host: [r730-01 dvl /etc/jail.conf.d] % sudo …

For my records, when it comes time to deciding what to use, this is R730-04.
This is one of the 4x R730 hosts, known as R730-02.
