Migrating drives and the zpool from one host to another.

Leave a Comment / DELL, Disks, hardware, Open Source, R710, R720, ZFS / By /

Today is the day. Today I move a zpool from an R710 into an R720. The goal: all services on that zpool start running on the new host. Fortunately, that zpool is dedicated to jails, more or less. I have done some planning about this, including moving a poudriere on the R710 into a jail. Now it is almost noon on Saturday, I am sitting in the basement (just outside the server room), […]

Moving poudriere from the host into a jail

2 Comments / FreeBSD, iocage, Open Source, poudriere / By /

This post is all about moving poudriere from the host into a jail, but you could probably use it for creating a new jail and running poudriere in it. NOTE: If you’re looking for a jail configuration for poudriere, please refer to Configuration for running poudriere in a jail on FreeBSD 14 – it contains new stuff, like mlock (thanks to feld for pointing this out). This also assumes use of iocage, but

My plan for moving the R710 into the R720

Leave a Comment / FreeBSD, hardware / By /

Today the drive caddies arrived for the R720. I refer to the services provided by the R710, not the server itself. I will list those services later and outline how I want to move them. I could do all this over this coming weekend but I have already allocated that time to some errands I have to catch up on. Physical things This section discusses the physical things which must move.

Creating a mirror from your zroot

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

I planned to create a zroot mirror when I installed FreeBSD on the R720 but the supplier shipped only one of the two purchased SSDs. Today the second drive arrived. Let’s create a zroot mirror. In this post: FreeBSD 12 man 8 zpool Posts I looked at: creating a mirrored ZFS Pool out of a single-disk rpool – not FreeBSD Convert Single disk ZFS-On-Root to Mirror – used the GUID via zbd; I

Preparing the Dell R720 for ZFS

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

I have obtained a Dell R720 containing 10 x 400GB SSDs. The drives are connected to a RAID controller (H710P) which cannot do JBOD / IT mode. This means the drives are effectively hidden from ZFS, which is never good. In this post: FreeBSD 12.0 ZFS Dell R720 SAS 9207-8i This post describes past work and future plans for this server as I get it ready to be a general purpose server running

scripts for monitoring vulns in FreeBSD jails

Leave a Comment / FreeBSD, Jails, Nagios, Security / By /

I have scripts for monitoring vulns in FreeBSD jails. They use third-party scripts. All I wrote was the Nagios part of the solution. I was preparing slides for my Why I prefer thick jails over thin jails talk at EuroBSDCon 2019. There is still time to register and attend. I was explaining my scripts and was providing links to gist.github.com … I realized I should create a repo: https://github.com/dlangille/freebsd-nagios-jail These scripts do the

poudriere hooks

Leave a Comment / poudriere / By /

zi0r suggested I use hooks to accomplish my patches-outside-distfiles question. In this post: FreeBSD 12.0 poudriere 3.3.2 I started reading the documentation and played with the supplied sample files in /usr/local/etc/poudriere.d/hooks. For background, see FreeBSD custom port patches when using poudriere. Eventually I came up with this solution: mkdir during the start phase mount during the mount phase I put stuff into a gist first, then created this post. The hook This is

Installing Owntracks recorder on FreeBSD

Leave a Comment / MQTT, OwnTracks / By /

I went and did a thing. I ported OwnTrack Recorder to FreeBSD. In this post: FreeBSD 12 owntracks/recoder 0.8.4 I refer to owntracks/recorder as ot-recorder. The FreeBSD service is known as otrecorder On FreeBSD, ot-recorder runs as the ot-recorder user, created by the package. I did not want it running as root. ot-recorder installs mosquitto by default, because it needs it’s libraries. That is also the reason why it installs curl. I chose
