I’m using Bacula 9.0.3 for this post, on FreeBSD 10.3 and 11.1. I did not document this as I went along, however, the details should be enough to get you started. NOTE: when I refer to the bacula-sd configuration, I mean the bacula-sd in question, not necessarily on the same server as bacula-dir. This will […]

Sometimes stuff gets swapped out. When it does, it’s good to know what is swapped. I was getting this Nagios alert this morning. I started searching. I found this post about showing what is using swap via: [dan@knew:~] $ ps ax | awk ‘NR==1{print};$3 ~ /W/’ PID TT STAT TIME COMMAND 12 – WL 54:27.37

For future reference, this is the knew server. It runs a few jails, including Bacula regression testing services. File systems Paritions zpools /var/run/dmesg.boot
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 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
After replacing 3TB drive with 5TB drive, FreeBSD 10.3 system did not reboot Read More »
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

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

I have a system with three tape drives and two tape changers. If one tape library is powered off when the system boots, the device names for the other tape library may be skewed. That is, /dev/sa0 may not be the LTO-4 drive, it will be the SDLT drive. This is not ideal. FreeBSD uses

The knew server is ‘frozen’ again. This has been happening daily at about O301 UTC each night. See my Twitter feed for background. In this post I will include details as I progress through the data. The server in question is knew (yes, that’s the hostname). dtrace hotkernel I left this running in an ssh
