Replacing a failed drive in ZFS on FreeBSD

1 Comment / Disks, FreeBSD, Open Source, ZFS / By /

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 in the system. In my case, this was: $ sudo gpart create -s gpt da0 da0 created $

smartctl -t long /dev/allthedrives

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 through this command: I suspect I could have done similar with ls /dev/da*. With the above list, I

Nagios check_ntp_time failed with ntpd on FreeBSD 10.2

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

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 showed: [dan@webserver:/usr/local/libexec/nagios] $ ./check_ntp_time -4 -H varm -t 1 CRITICAL – Socket timeout after 1 seconds I checked

Configuring unbound on FreeBSD 10.x

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 disable). I now return you to the original article. Today I was setting up my new server, varm,

New external HDD

While in Ottawa for BSDCan 2015 and PGCon 2015, I obtained a 4TB external USB HDD. It now contains copies of the videos back to 2012 for BSDCan and PGCon. This is for backup. All these videos exist elsewhere (e.g. Youtube) and I have these just for backup. NOTE: the videos for BSDCan 2015 and PGCon 2015 will be online as soon as they are available. There is no ETA. Here’s what it

Following on from my post about excluding the base OS with a Bacula FileSet, I decided to exclude some more. The starting point Here are the baselines: What else will I exclude? I decided to exclude the following as well: Adding iocage support Along the way, I extended the Exclude to work on server using the iocage jail management tool. I also split the Exclude out into its own file. Here is the
