Yes, this was not fun. I took some notes, but not everything. Please read the notes if you plan on doing these foolish things. I was cleaning up /usr/src on a host which does not hold src. I looked and found: It was there that I knew I’d done the wrong thing. Trying snapshots Let’s

I’m using FreeBSD 10.2-RC2 here, with a bunch of HDD. Here are the current pools: The degraded music pool contains a drive I will be replacing later in this post. But first, I want to replace a mis-matched drive in the benchmarking pool. I noticed that when I saw this output: The serial number on

NOTE: If you are looking to configure net-mgmt/net-snmp for the first time, the latest article is Configuration of net-mgmt/net-snmp on FreeBSD. I wasted a few hours today trying to figure out why special characters in passwords were causing problems. I was chasing the wrong problem. Conclusion: smart quotes are dumb. Full disclosure: I should have

I’m using FreeBSD 10.2-RC2. One of my new hard 3TB drives was acting up. I removed it and sent it off to be replaced. In the meantime, I received some 5TB drives and I added one of them into the existing vdev of the zpool. First, I partitioned the drive much like the other drives

I took delivery of another 10 x Toshiba PH3500U-1I72 5TB drives yesterday. They are installed into the latest server (varm). This sever also contains 10x Toshiba DT01ACA300 3TB drives. Last night I wrote a wee script to start long tests on each of them. I was able to extract a list of the hard drives

As I was setting up the new varm server, one of the Nagios checks I included was check_ntp_time. It comes standard with nagios-plugins. The check was reporting NTP CRITICAL: Offset unknown. Running the check from the command line showed: [dan@webserver:/usr/local/libexec/nagios] $ ./check_ntp_time -4 -H varm NTP CRITICAL: Offset unknown| Running the check with a timeout

NOTE: I found out these settings do not persist after a reboot. Annoying. I’ll get back to that soon for a fix. EDIT 2021-05-05: On more recent FreeBSD, say 12.2, to disable resolvconf.conf, do this, as provided by [dvl@r720-02:~] $ cat /etc/resolvconf.conf resolvconf=NO [dvl@r720-02:~] $ The above is documented in man 8 resolvconf.conf (search for

World, please meet varm, the newest addition to my home lab. Some of the hardware has been described in an earlier blog post and not all of the hardware has been installed. But for the record:
