I know, I know. You can hardly contain your excitement as you read about my exploits. In this post, I add the drives into the host and run some simple tests. As in recent posts about 12T drives, these drives are not new. They are used drives. A later post will deal with the commands which add these new drives into an existing zpool. These drives came from serverpartdeals.com. They are used and […]

I have used Tarsnap since at least 2017. The jobs ran nightly. It wasn’t until three years later, that I started cleaning up old backups. Now I’ve found a tool which manages this for me (sysutils/acts) courtesy of a toot by M W Lucas. The selling point of this tool: By default, 31 daily, 12 monthly, and indefinite yearly backups are kept. Sounds good enough for me. I’ll buy that. The install and

This is the Dell R730 host known as r730-03. It replaces an earlier post. This new post was created because the network card was changed from a 1G fiber card to a 10G fiber card. gpart zpool list zpool status File systems dmesg sesutil show jls
I run poudriere in a jail on FreeBSD – it really is becoming the thing-to-do with all the cool kids. Everyone’s doing it. It is nifty. I will provide only the jail configuration, and not any file system configuration. That is left for you. I think these links might be most helpful: Using poudriere to create a custom FreeBSD repository for package installation Moving poudriere from the host into a jail In this

It is time to let the knew server go. It has gone through multiple upgrades, new drives, new boards, and new chassis. It has been replaced by r730-03. Before I let it go, I want to clear off the drives. By that I mean: I did this by booting the host using mfBSD (a lovely USB-bootable version of FreeBSD). I then ssh‘d in as root (one of the few situations when ssh as

This is a rewrite of a previous post on the same subject. I have rewritten it because I created a new jail ™ and I’m using a different configuration now. I recently moved a Time Capsule instance from a FreeBSD host into a jail. Later, I moved to using 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.

A friend introduced me to monitor lights earlier this year. I thought about getting one, but didn’t. I added it to my wish-list and I recently received one. I really like it. As an Amazon Associate I earn from qualifying purchases. This is what I bought: OOWOLF Monitor Light Bar with Remote Screen Light Bar (Amazon link). I took these photos one evening in my office. See the URL above for details.

On FreeBSD, you can jail a ZFS dataset – that is, the jail can manipulate the ZFS dataset as if it was a host (more or less). This has useful applications. In my case, I want to backup a snapshot of that dataset from the host. For example, I want to backup this dataset: [12:19 r730-01 dvl ~] % zfs list data02/freshports/jailed/dev-ingress01/data/latest_commits NAME USED AVAIL REFER MOUNTPOINT data02/freshports/jailed/dev-ingress01/data/latest_commits 572K 798G 120K /var/db/ingress/latest_commits Within

Tonight, while watching an episode of The Great British Bake Off, I configured a new Bacula backup jobs to cover some datasets which were not already backed up. I already have a backup jobs to backup all the jails, but only for datasets which sit right under zroot/jails (for example). This new solution takes a list of datasets, snapshots them, backs them up, then destroys those snapshots. Why backup a snapshot? Consistency. During

Librenms is my tool-of-choice for grabbing metrics from switches, servers, wireless access points, and anything else with an snmp interface. In this post: FreeBSD 14.0 LibrenMS 23.11.0,1 – updated to 23.11.0_1,1 within this post net-snmp-5.9.1_4,1 After updating some hosts to FreeBSD 14, the zfs application/extension broke. It was quickly amended after a report was lodged. However, after the fix, I still wasn’t getting graphs. It was nan all across the board for ZFS:
