Adding in a stand-by spare drive for ZFS on FreeBSD
This is a follow up to Adding in a hot-spare for zfs on FreeBSD from two months ago. The replacement for the returned drive has arrived and after sitting for many weeks on my coffee table, it is installed in r730-03. Here it is, as found in /var/log/messages – this host is a Dell R730 which has drive cages allowing me to insert the drive without powering off the host. Jun 30 16:17:15

Steps for adding a new laptop
I have a new-to-me-laptop. This post isn’t about setting it up, installing applications, etc. Nor is it about copying data from the old laptop to the new laptop. This post is about the configuration things which are specific to this laptop, which is known as pro05.int.unixathome.org. It will cover several steps that, because they are carried out so infrequently, I don’t always remember them. Hopefully, this will help me the next time I

Making sure I remove the correct drive
Yesterday, I discovered I had removed the wrong drive from a zpool. In this post: FreeBSD 14.2 Today, the zpool replace command has completed. Next, I carefully chose the right drive to pull from the drive bays. Status This is the zpool status, just before it completed: After it completed: I see gpt/SG_ZHZ16KEX is no longer in the zpool.

I just added my first hot-spare to a zpool.”, ivy told me “noooooooo don’t use hot spares!! Keep a cold spare or at least an online device not attached to a pool. otherwise your zpool will randomly decide to attach its hot spare due to a temporary cabling issue or something like that. the

Installing the replacement UPS
Around the end of last year, I started having trouble with my used Eaton 5PX – I’d had it for about 5 years and it was used when I bought it off eBay. On Saturday night (about 21:33:48 UTC), the home network disappeared off the Internet. I figured my new gateway had died. The dead UPS Sunday morning, I returned from the remote undisclosed location to the basement #homelab. Entering the basement, it

gw01 – setup photos – very little commentary
Earlier today, I installed FreeBSD 14.2 on gw01. EDIT: 2025-02-11: Yesterday, I found out the gateway draws 22W. And yes, as an Amazon Associate I earn from qualifying purchases.
