In this post I will be creating a ‘new’ jail which uses vnet. I say ‘new’ because I am actually Converting an iocage jail to a vanilla jail which happens to use vnet. NOTE: I originally failed to get this to work. You can read about it. I’m going to repost this article soon with a working solution. I won’t describe the process of creating the jail. Sorry. For the record: FreeBSD 12.2 […]

I like boot environments (BE) on FreeBSD. They were especially handy when building the AWS host for FreshPorts, since I had no serial console. I would create a BE saving the current status, then make some changes. I’d mark the current BE as boot once, so I could boot back in the known good BE. Worst case, I could mount the storage onto a rescue EC2 instance and adjust the bootfs value of

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. snmpd can be royal pain to configure. I got my hints from Ryan Steinmetz, the maintainer for the FreeBSD port. Lately, net-snmpd has changed how net-snmp-config works. In this post: FreeBSD 12.2 net-snmp-5.9_3,1 Compare my hints with the following, run today with net-snmp-5.9_3,1: [dan@nginx01:~] $ sudo net-snmp-config –create-snmpv3-user -ro -x AES -a

Tonight I got blocked by iocage and handling a ZFS filesystem from within an iocage jail. These are the steps I followed to convert that jail from iocage to a vanilla jail. The variable To make this solution easier to use, at least for me, on future jail migrations, I have these variables: For example, my devgit-nginx01 jail is at: [dan@knew:~] $ zfs list system/iocage/jails/mysql56 NAME USED AVAIL REFER MOUNTPOINT system/iocage/jails/mysql56 11.5G 20.6T

I have a few development jails dedicated to my work on FreshPorts. It’s been a hobby of mine since the late 1990s. The code I create gets packaged, ready to deploy onto the test, stage, and production hosts. What I absolutely do not want to happen, and it’s happened recently, is for those packages to be installed on the development environments. Why? It installs to the same location as the working copy of

Yesterday, I started a zpool replace. It finished overnight, and dropped the suspect drive out of the vdev. The resilver finished in the middle of the night: As you can see, da22p1 has taken the place of da17p1. The resilver took As the new drive is being resilvered, I started looking at metrics. Here is gstat. Look at how da22, the replacement drive is getting all the writes, compared to the others. LibreNMS

It is time to replace /dev/da17 in knew. The replacement drive is also documented. The replacement procedure has also been documented. An upcoming blog post will document the replacement. I’m seeing these messages: Dec 12 09:23:03 knew smartd[2124]: Device: /dev/da17 [SAT], 40 Currently unreadable (pending) sectors Dec 12 09:53:04 knew syslogd: last message repeated 1 times Dec 12 10:23:03 knew syslogd: last message repeated 1 times Dec 12 10:53:04 knew syslogd: last message

Virtual hosts for a website are a thing. One webserver can host multiple websites. They can all be on the same IP address, different IP addresses, different ports, etc. This post is about using a proxy service. Before I started with this solution, at home I hosted every website on the same server. My firewall would redirect incoming ports 80 and 443 to my webserver, and Nginx/Apache would take care of the rest.

This work was done in August. Since then, I have replaced the APC with an Eaton 5PX, and I am much happier. This might make for interesting reading, but that depends on how bored you are.. Following on from my failed calibration attempts, I thought I would try it again this morning before work.

I have these boot drives, I want to copy them to another. They both happen to be zroot and bootable. I booted from mfsBSD and imported both new and old zroot, using the pool ID shown by zpool import -N. root@mfsbsd:~ # zpool import -N pool: data01 id: 2668514456528412656 state: ONLINE action: The pool can be imported using its name or numeric identifier. config: data01 ONLINE mirror-0 ONLINE gpt/S59VNS0N809087J_S00 ONLINE gpt/S59VNJ0N631973D_S01 ONLINE mirror-1
