Adding two more 12TB drives to the mirror

Leave a Comment / DELL, FreeBSD, hardware, Open Source, R730 / By /

As mentioned in several previous posts, I’m moving a server from one chassis to another. None of the hardware is coming over. Just the jails and data. These drives came from serverpartdeals.com. They are used and re-certified. Recently, I’ve been trying out two new 12TB drives. I’m looking forward to the reduced noise level, as well as the reduced power consumption and heat. In this post: FreeBSD 13.2-RELEASE-p2 The testing zpool I created […]

Bacula – copying the latest jobs over from one SD to another

Leave a Comment / Backups, Bacula, FreeBSD, Open Source / By /

I want to copy the latest backups for each Bacula client over to a new host. I already do this, on an automated basis, for recent backups, primarily to have the same backups in two different places. In this case, I want to do this once. This post might also be a good introduction to copying / moving jobs based on SQL queries. See also Bacula – copy to tape by job size

kernel: pid 4900 (conftest), jid 968, uid 65534: exited on signal 11 (core dumped)

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

I see see these log messages on a regular basis. There is no distinct pattern. Some nights there might be 1, others 2. Today there were three: r730-01 is my main server in the basement. It runs a jail named pkg01, which does my nightly poudriere builds. Those jobs are launched from this crontab: That UID relates to nobody and matches up with what poudriere does (runs as nobody).

Bacula – calculating Maximum Volume Bytes and Maximum Volumes based on historical data

Leave a Comment / Bacula, FreeBSD, Jails, Open Source, quota, sanoid, snapshots, ZFS / By /

I’ve used Bacula since at least January 2004 (so nearly 20 years). I liked it so much I dropped my deployment-in-motion of another tool (if you search lightly, you can find out which one). I liked it so much, I wrote a PostgreSQL backend for it. This post is not for Bacula novices. This post is for those who have already deployed a Bacula instance and are rather familiar with the process. I

Configuration of net-mgmt/net-snmp on FreeBSD

Leave a Comment / FreeBSD, Open Source / By /

Today I’m setting up snmpd on a new [to me] host. It’s a Dell R730. Previously, my documentation for this was a bit jumbled. It was written in 2015 and contains a few updates and corrections. It was hard to follow, even for me. This new post is an update of that one. See my FreeBSD Forums post where I spent a long time figuring out why the JAIL option needs careful consideration.

Identifying jails and data to migrate from old host to new host

Leave a Comment / FreeBSD, hardware, Jails, Open Source, R730 / By /

I’m retiring knew and moving the services over to r730-03. I recently added 2 12TB drives to the latter host. In this post, I’ll start the migration process by identifying what data needs to move, from where, and to where.

Changing how I use IP address with FreeBSD’s vnet – so IPv6 works

Leave a Comment / Jails, vnet / By /

The vnet (network subsystem virtualization infrastructure) on FreeBSD is both a blessing and a curse. For me, it isn’t working well with IPv6. I’ve hit issues with pf (since solved, I’m sure). It’s a useful feature but can be confusing. It helps to have lots of time to think about it and what you’re doing. I talked about this amongst the FreeBSD jail group and out of that came a blog post: The

Using FreeBSD’s daemon(8)? Consider -r

Leave a Comment / FreshPorts, Open Source / By /

FreshPorts make use of a simple python daemon (fp_listen). It has been in use since at least 2006. It was (I think) vermaden who mentioned it (I can’t find the reference) and it triggered an idea. The role of fp_listen is to listen for backend notifications and respond accordingly. One of its primary goals is to clear the front end cache as required. Part of that strategy involves a persistent connection to the

vnet jail on FreeBSD not letting pings through from another non-vnet jail

Leave a Comment / FreeBSD, Jails, vnet / By /

NOTE: this problem was fixed by moving all the IP addresses to the bridge. See Changing how I use IP address with FreeBSD’s vnet – so IPv6 works I just restarted my pkg01 jail. Now Nagios can’t see it on IPv6. In fact, none of the jails on this host can now ping pkg01. This is FreeBSD 13.1-RELEASE-p6 I did try DAD (based on this previous post, but that’s no help here).
