Yesterday I did some scavenging of some servers which I’m going to dispose of. I managed to put together 4 x 1TB storage devices: 2 x NVMe sticks and 2 x SSDs. I also pulled a riser card from an R730 and relocated it to another host. The NVMe sticks are mounted on these PCIe …
After powering off the server about 8 months ago, I took the first steps to selling it. I opened it up and took out 2x NVMe sticks (1TB each, ZFS mirrored, giving a 930G zpool) INTEL fiber NIC (Intel X540-AT2) I’ll be keeping those items. I also took an inventory of the drives still in …

Today, while mucking about with a new cronjob and log file for acme.sh, I stumbled across these error messages: Why was I stumbling around?

Let’s look at that file: [18:37 certs dan ~] % sudo ls -l /var/db/acme/certs.int.unixathome.org.key -rw-r—– 1 root acme …

NOTE: on yesterday’s (2023-10-04) reboot, the file systems did not properly mount. zfs get mounted said they were …

I have Macbooks at home I use them. I use Time Capsule on ZFS on FreeBSD to back them up. In this post: FreeBSD 13.2 OSX Ventura 13.6 I first implemented this directly on the FreeBSD host. Today, I am moving that service into a jail. This post will roughly outline the changes I made …
