Why is my network offline? An investigation

Leave a Comment / General / By /

Happy New Year. This morning I received an email at 4:50 AM local time telling me that my camera system had been offline for 10 minutes. Based on that, I tried to access my internal monitoring system from outside. Nothing. Later emails indicated other external systems had issues connecting to the internal network. As I type this, I just arrived at home, I’m sitting on the couch and I’ve not touched the network […]

Moving bacula-sd into a FreeBSD jail

In this post: Bacula 7.4 FreeBSD 11.1 py-iocage 0.9.9.2 I recently wrote about Converting a Dell R710 into a ZFS-based FreeBSD 11.1 tape library bacula-sd and then about getting the drives ready. That system, henceforth referred to as the r710 is now ready for the Bacula setup. Last night I created a jail and installed the software I’ll need. Most of this was done via Ansible. I also configured Bacula both on the

R710

I’ve been given a Dell PowerEdge 710. I’ve installed two 30GB SSDs, installed FreeBSD 11 on them, and added four 500 GB SSDs. It will become a tape library server, replacing the R610 which will no longer be used. Some of the hardware came from the R610. The zpools: The filesystems: And dmesg:

Today I moved the FreshPorts website from one server to another. My goal is for nobody to notice. In preparation for this move, I have: DNS TTL reduced to 60s Posted to Twitter Updated the status page Put the website put in offline mode: Sorry, the website is offline from 2017-11-05 17:01, for approximately 3 hours.

Dumping PostgreSQL 9.4 to upgrade to PostgreSQL 9.6

Leave a Comment / ezjail, FreshPorts, Jails, PostgreSQL / By /

FreeBSD 10.3 & PostgreSQL 9.4 on the old server, and FreeBSD 11.1 & PostgreSQL 9.6 on the new server. As part of the move from the old FreshPorts server (photos) to the new FreshPorts server, I’ll need to dump the database and copy it over. What? No zfs send? There is no ZFS on the old server. The rule of thumb when upgrading a PostgreSQL database is to dump with the pg_dump client

Yesterday, I upgraded a DigitalOcean droplet from FreeBSD 10.3 to FreeBSD 11.1 just before I headed to work. I’ve done such upgrades several times before. They all went well. This one did not. Several issues cascaded to prevent me from completely this task in a timely manner. Let me describe the events as they unfolded.

Upgrading from FreeBSD 10.3 to 11.1 via freebsd-update and beadm

Leave a Comment / beadm, ezjail, FreeBSD, Open Source, Upgrades, ZFS / By /

Yesterday I modified a server from booting off a raidz2 array, to booting off a newly created zpool. Why? Because HBAs are a pain to boot off. Instead, this server is now booting off a ZFS mirror of two SSDs, both of which are directly attached to the M/B. Today, I am upgrading this server from FreeBSD 10.3 to FreeBSD 11.1 by making use of beadm. WARNING! Not all steps of the freebsd-update
