using syncoid to backup ZFS snapshots – home assistant

Leave a Comment / sanoid, snapshots, syncoid, ZFS / By /

Copies of data are good. Especially if on a different host. zfs snapshots combined with zfs send | zfs recv make replication of zfs file systems especially easy. I am already using sanoid to manage zfs snapshots. Now I’m going to use syncoid to transfer those snapshots to another host. Both sanoid and syncoid are provided by the sanoid package on FreeBSD. I’m sure any other packaging system does similar. In this post: […]

openvpn: error=CRL has expired

2 Comments / Open Source, OpenSSL, ssl-admin / By /

After the former FreshPorts server was retired, its OpenVPN credential were revoked. I maintain those certificates via ssl-admin. I uploaded the new CRL into the System | Certificate Manager | Certificate Revocation page in pfSense. Today, I was seeing strange errors in Nagios, and figured someone wasn’t connected to the VPN. Checking OpenVPN client logs, I found nothing. On the OpenVPN server, I found this message: Oct 23 22:14:23 openvpn 11134 203.0.113.144:20690 VERIFY

Upgrading an NVMe zpool from 222G to 1TB drives

Leave a Comment / FreeBSD, Open Source, smartctl, ZFS / By /

The FreshPorts dev, test, and stage websites are hosted on a server in my basement. Each instance consists of two jails: an ingress node – for pulling in new commits (and other data) into the database. a webserver node – for displaying the web pages. The new drives: Sometimes the zpool gets too close to full. I tweeted about one incident on March 2021. I held hope that some spare SSDs might be

da12 in my FreeBSD zfs array disappeared at :02 and came back at :04

Leave a Comment / ZFS / By /

This post is based on a tweet and was created after a followup incident occurred today. The post was created to consolidate the information into a blog post so I could easily find it later. Details about this host (disks, zpool, gpart, etc) are in this post. On March 15 2022, I noticed these messages in /var/log/messages: The zpool array was degraded. I don’t have a record of that message. The tweet also

I stopped it before doing these

Getting Home Assistant running in a FreeBSD 13.1 jail

15 Comments / FreeBSD, General, homeassistant, Jails, Open Source / By /

Home Assistant is not friendly for plain installs. It seems designed for containers or running everything out of pip install. That, in itself, is a disturbing trend I’ve seen on several projects (what? you’re not running a git cloned image?). I’ve seen reports of people running containers etc. However, I want to run this on FreeBSD. I don’t want to muck about with installing containers etc. If containers are the only way for

nsupdate – update failed: REFUSED

Leave a Comment / DNS, named, nsupdate / By /

A while back, the https://www.freebsddiary.org/topics.php#opteron – the colo facility was purchased and the new owners are not interested in donating services to open source projects. That host also acted as a DNS host for all my domain. I pressed a small VPS into service. It handled the query services fine, but updates were sluggish. It took a few hours for it to catch up to Let’s Encrypt renewals. To be fair, this $5

Grace Hopper – My impressions

Leave a Comment / Conferences, GHC / By /

I wrote this in October 2016. It was not published until August 2022. I loved being at Grace Hopper. I met some very great people and had the opportunity to talk to them about open source software. I got some great ideas from some folks and I sure hope the stuff I passed on will encourage others to take up open source. There’s money at Grace Hopper. Lots of money. I counted 9
