Stuff goes wrong. I like to check. Trust. But. Verify. Skip to the end for the list of useful commands. Here’s some of that verification, as briefly mentioned in FreeBSD 14 upgrade – files not removed by delete-old and Excluding some jails from upgrade. After upgrading all the jails on r730-01, I wanted to make sure that all the binaries had been updated from FreeBSD 13. Here’s what I did. This tells me

I have some jails already updated to FreeBSD 14 – let’s get a list of what needs to be updated. This cold just as easily be used to get a list of what not to upgrade, if you didn’t want to update all jails right now. These jails are already updated: [15:30 r730-01 dvl ~] % file /jails/*/bin/sh | grep 14 /jails/bacula/bin/sh: ELF 64-bit LSB pie executable, x86-64, version 1 (FreeBSD), dynamically linked,

This is a rewrite of Jails with embedded, but not jailed, ZFS datasets – how to mount/umount. First, this is not about jailed ZFS datasets. I use them for FreshPorts, but that’s not I’m going to talk about here. In this post: FreeBSD 13.2 This is my example: [22:25 r730-03 dvl ~] % zfs list | grep bacula-sd-04 data01/bacula-volumes 12.1T 4.18T 96K /jails/bacula-sd-04/usr/local/bacula/volumes data01/bacula-volumes/DiffFile 109G 915G 109G /jails/bacula-sd-04/usr/local/bacula/volumes/DiffFile data01/bacula-volumes/FullFile 4.00T 2.00T 3.89T /jails/bacula-sd-04/usr/local/bacula/volumes/FullFile

This post has been replaced by Creating a Time Capsule instance using Samba, FreeBSD, and ZFS (latest) I recently moved a Time Capsule instance from a FreeBSD host into a jail. Today, I’m going to create a new Time Capsule which uses Samba instead of AFP. Why? Samba seems to be the preferred solution because AFP has been deprecated. It still works, but let’s go Samba. Not covered in this post, but recommended:

This approach did not work, because I used the wrong set of filesystems. See below for Error. This post has been replaced by Jails with embedded, but not jailed, ZFS datasets – how to mount/umount – corrected. NOTE: on yesterday’s (2023-10-04) reboot, the file systems did not properly mount. zfs get mounted said they were mounted, but the directories were empty. Stopping, then starting the jail resulted in a proper mount. I wonder

I’ve used Bacula since at least January 2004 (so nearly 20 years). I liked it so much I dropped my deployment-in-motion of another tool (if you search lightly, you can find out which one). I liked it so much, I wrote a PostgreSQL backend for it. This post is not for Bacula novices. This post is for those who have already deployed a Bacula instance and are rather familiar with the process. I

I’m retiring knew and moving the services over to r730-03. I recently added 2 12TB drives to the latter host. In this post, I’ll start the migration process by identifying what data needs to move, from where, and to where.

The vnet (network subsystem virtualization infrastructure) on FreeBSD is both a blessing and a curse. For me, it isn’t working well with IPv6. I’ve hit issues with pf (since solved, I’m sure). It’s a useful feature but can be confusing. It helps to have lots of time to think about it and what you’re doing. I talked about this amongst the FreeBSD jail group and out of that came a blog post: The

NOTE: this problem was fixed by moving all the IP addresses to the bridge. See Changing how I use IP address with FreeBSD’s vnet – so IPv6 works I just restarted my pkg01 jail. Now Nagios can’t see it on IPv6. In fact, none of the jails on this host can now ping pkg01. This is FreeBSD 13.1-RELEASE-p6 I did try DAD (based on this previous post, but that’s no help here).

It’s good to do automated backups. When you do that, add monitoring to make sure the backups are occurring successfully. In my case, I backup using Bacula. Each job creates a new .bsr file. I copy these files to another location each day. Then I monitor the dates on those files and they should all be less then a day or so old. Edit (added 2023-08-29) This post is about upgrading net-mgmt/unifi6 to
