Yesterday, I mentioned I wanted to compare raidz2 when using 10 disks versus using 8 disks. Along the way, I noticed that my ZFS-setup script needed a change to cope with mixed devices. Once I got past that hurdle, I started adding packages and setting up the system for some very simple tests. The test [...]
THe last system I set up with ZFS, I used a script. Today, when trying a system with different device types, I encountered a limitation of that script. I need to fix it. In the above script, NUM takes on the value of what digits appear in the string of I. Given that DISKS contains [...]
Indiana LinuxFest will be held at the Wyndham Indianapolis Hotel in Indianapolis, IN from Friday July 26 to Sunday July 28. Registration is free for this event. There will be a BSD booth in the Expo area on Saturday from 8:00–18:30. We will be giving out PC-BSD DVDs, FreeNAS CDs, and other cool swag, as well as accepting donations to (Read m [...]
The traditional thoughts on ZFS are to have arrays which are a power-of-2 when it comes to number of disks. That means 2, 4, 8, etc. But for raidz1, that would be 3, 5, 9. For my choice of raidz2, it would be 4, 6, and 10. In the system I’m building up now, I [...]
Indiana LinuxFest will be held at the Wyndham Indianapolis West Hotel in Indianapolis, IN from Friday July 26 to Sunday July 28. Registration is free for this event.

Do you have a Emulex OneConnect 10Gb NIC? Well good news! Sascha Wildner brought in updated the oce(4) driver from FreeBSD to support Skyhawk models in DragonFly. (My bad; looked at the wrong oce(4) commit originally and re-reported the import instead of the update.)
My gateway is dying. My file server is getting full. Over the past few weeks, I’ve been dealing with aging infrastructure. My development server started acting up and was showing signs of age. This aging desktop box contained 80GB HDD, which means it’s probably 6 or 7 years old. That’s getting on in age. It’s [...]
I made a hesitant attempt to keep an eye on other BSD source changes over the last week. I complain about needing coverage for the other BSDs, so I’ll see what I can do: (Parts of?) full-disk encryption support in NetBSD. esp (the SCSI board) support for NetBSD/acorn. SipHash support in FreeBSD SYN Cookie support in FreeBSD.
The April-June, 2013 Status Report is now available with 33 entries.
We’ve never had a group of student post progress this regularly. It’s great! Daniel Flores: HAMMER2 compression feature Larisa Grigore: System V IPC in userspace Pawel Dziepak: Make vkernels checkpointable Joris GIOVANNANGELI: Capsicum Mihai Carabas: hardware nested page table support for vkernels
Open Help is an annual conference for people who write documentation for an open source project. The Foundation sponsored Warren Block from the FreeBSD documentation team to attend this year. He writes:In June, I attended the Open Help Conference in Cincinnati, Ohio. Open Help focuses on open source documentation. Dru Lavigne atte [...]
Busy, busy week. An in-depth programming language comparison. These can be fun for reinforcing your language choices, but also interesting just for the depth of comparison. Spoiler: Java can be crazy slow; Perl can be crazy fast. The page has lots of charts which always make me happy. The quotes at the end per-language are enjoyable. (vi [...]
Something new and odd: A port of the Hammer (1) filesystem into Go, for go-fuse. As the author has said, it’s more for the practice of learning Go and Hammer than for producing anything useful. Still, an interesting way to learn.
As usual, a lot of interesting things are going in The Internet, here are some that caught my attention: 1) Mozilla Persona A better way to sign in. It can be used to implement SSO (Single-Sign-On), in someway it is similar to OpenID. The identity provider is not notified, which is very good for privacy. … Continue reading →
BSDTalk 228 has a nearly half-hour chat with Michael W. Lucas at BSDCan 2013.
I was trying to recompile sysutils/bacula-client on a FreeBSD 8.4 jail when I encountered some perplexing link errors. It took me a while to figure it out, but with the help of some IRC conversation, we figured it out. I started off by deleting the old (quite old) port: bacula-client-5.0.3 Then I recompiled: cd /usr/ports/sysutils/bacula-clie [...]
Michael W. Lucas auctioned off his first copy of Absolute OpenBSD, 2nd Edition some time ago, with the proceeds going to the OpenBSD Foundation. It was to be signed by OpenBSD developers – which is neat enough, but apparently it was annotated by the developers, too.
Apparently Sepherosa Ziehau has been improving DragonFly’s route table performance under extremely heavy load. (e.g. run efficiently; don’t die) I don’t have a definitive commit message to point at, but looking at his recent commits are a good start.
