I recently obtained two 4TB NVMe cards and two PCIe adapters, each of which holds two NVMe cards. This is what they looked like fully loaded: The thinner NVMe is the new 4TB card, and the thicker card is the 1TB card, with heatsink, which I’ve had for some time. Yesterday I noticed the NVMe cards were not parallel with the adaptor. Earlier today, I fixed that. First, let’s look at the angles. […]

This post is mostly for my benefit, so I can keep track of my plan for adjusting space. It doesn’t contain much of educational value. For what I actually did, see zfs: setting compression and adding new vdevs One recent day, I powered off r730-01 and took inventory of the 16 drive bays. A short overview: [17:36 r730-01 dvl ~] % zpool list NAME SIZE ALLOC FREE CKPOINT EXPANDSZ FRAG CAP DEDUP HEALTH

FreeBSD has a great concept of establishing default values and letting the user override them. That approach does not apply to newsyslog, and specifically, newsyslog.conf This idea came up on IRC after I said I was looking forward to a new FreeBSD 15 which allows the compression specified in newsyslog.conf to be overridden. Using /etc/newsyslog.conf.d Getting a clean copy First, I grabbed a pristine copy of /etc/newsyslog.conf from the repo: [12:34 r730-01 dvl

Today I was trying to access my Dell 730 (r730-01) via the remote console. I failed. Twice. First and expected failure First, this was usual and expected. It’s been a problem both at home and at work. It is the inability to access the console via https using the hostname This is what I see: I can get in via IP address though. Second and new-to-me failure Next, after logging in via IP
Recently I’ve been playing with NVMe to find out more about monitoring for wear. Tried nvme-cli: [17:49 r730-01 dvl ~] % nvme list Failed to scan topology: No such file or directory Seems it is a known problem. Went with this instead: [17:52 r730-01 dvl ~] % sudo nvmecontrol devlist nvme0: Samsung SSD 980 PRO with Heatsink 1TB nvme0ns1 (953869MB) nvme1: Samsung SSD 980 PRO with Heatsink 1TB nvme1ns1 (953869MB) With more information

I have a jail on r730-01 called dvl-ingress01.

I’m ready to update r730-01 (I see that link is from 2024 – I’ll refresh it after this update) from FreeBSD 14.2 to FreeBSD 14.3.

I use Mac laptops. Have for years. I make use of their Time Machine backups. I configured Time Capsule instance using Samba, FreeBSD, and ZFS (latest) and today I added a new user to that configuration. Next, I wanted to start the backups. I didn’t find details in my blog, so that prompted this post. In this post: This post assumes you’re already configured the server (see above links). FreeBSD 14.2 samba 4.16.11

This is mostly for my future reference, for when this happens the next time. I hope it saves me 10-15 minutes of pondering. I noticed this problem a few days ago. I was clicking on links in an email from Disney. The hostname didn’t resolve. I passed it off as: well, they got problems… It happened again today. Hold on, this isn’t likely. I tried the link again, from my phone, with wifi
