This is about FreeBSD 11.1 on my knew server. I recently replaced the 3TB drives with 5TB drives. Along the way, it didn’t boot, the swap was adjusted, I got concerned about power, and there was a brief CAM status: SCSI Status Error scare. Then today, the planned reboot, I started asking questions on Reddit […]

I just swapped out a drive which was involved in a gmirror swap. This is the current status: $ gmirror status Name Status Components mirror/swap DEGRADED da0p2 (ACTIVE) da2p2 (ACTIVE) da3p2 (ACTIVE) da4p2 (ACTIVE) da5p2 (ACTIVE) da9p2 (ACTIVE) da10p2 (ACTIVE) Here is how I can fix that: sudo gmirror forget swap The above tells gmirror

In general, passphrase-less ssh keys are a security nightmare. It is similar to leaving the key to your front door in the lock. Anyone stumbling across it has access to your house. Similarly, if someone gets your ssh key, and there is no passphrase on it, they can use that key for anything which grants

I started replacing 3TB drives with 5TB drives in a 10 drive raidz3 array on a FreeBSD 10.3 box. I was not sure which drive tray to pull, so I powered off the server, and, one by one, pulled the drive tray, photographed it, and reinserted the drive tray. No changes were made. The first

This morning, I was reviewing the logs and noticed these notices in /var/log/messages: I guessed that this was directly related to the zfs replace command I had issued the day before, but I wanted to confirm that. I like to use sudo instead of becoming root. One of the many benefits to this approach is

In this power, the server is running FreeBSD 10.3. I am completely and unreasonably biased: ZFS is the best filesystem out there. Do not take my word for it. Ask around. Today, I started a process I’ve been waiting to do for a while. I am replacing the 3TB drives in a 10-drive raidz2 array

These steps were carried out on FreeBSD 11.0 with PostgreSQL 9.6 (two of my favorite tools). I like logging. I like logging PostgreSQL. With logs, you can see what happened. Without, you can only guess. Setting up logging for PostgreSQL involves several parts, each of which must be completed or else I don’t get what

This is mostly a note to myself. #### Edit: 2018.09.08 : If you see messages like this: $ sudo gmirror insert swap /dev/da5p2 gmirror: Class not found $ gmirror list -a gmirror: Command ‘list’ not available. You probably need to do this: sudo kldload geom_mirror #### I had these drives: They are involved in this

This post has been replaced by a newer one. For reference, the previous post on this server is still available. The most recent change was from 3TB to 5TB drives. For future reference, this is the slocum server, which I use for various jails and services. It is mounted in the 4U chassis mentioned in
Now that I have configured my webserver to pull down any new certificates, now it’s time to configure my clients to pull certificates from the webserver. In my quest for a centralized Let’s Encrypt solution, I’ve created the FreeBSD port for acme.sh (an ACME client for Let’s Encrypt) and anvil, a tool for distributing and
