Hans Reiser: Once a Linux Visionary, Now Accused of Murder

Interesting reading.

• First, I discover this afternoon that my server has rebooted on an older Kernel and the SATA drives aren’t being recognized. No wonder it’s going so slow; the RAID is running in degraded mode (not inherently slower for RAID0/mirroring, but in practice it’s going to mean that the system does everything much more carefully wrt flushing buffers and stuff.) So I had to rebuild that tonight; the Linux mdadm tool made that surprisingly easy.
• Second, the phone line has gone tonight. No DSL, no nuttin’ - I host my own server, so I can post this now, but who knows when y’all are going to get to see it. And I think I’m going into some minor case of internet-access withdrawal (no dialup backup, since the voice phone is down too, but at least I have my PDA thing… slow though it is at home.)

Two quick notes:
1) Wordpress 2.0 is out. I plan to upgrade when I get back to the states; I’m not convinced it’s really going to be an improvement, but I need to keep up to date with the security patches, so there’s not much choice. Hopefully my old style/theme will still work. If not, expect a very bland defauly style until I have more time…

2) ReiserFS sucks for news spools, even with “notail” on, at least on RAID1. I’d wondered if that was it, and it appears to be the case. My leafnode spool runs to about 1.5 million articles, and 9GB; when I put in the mirrored drives, I put it on it’s own file system and switched it from ext3 to ReiserFS. I noticed then that it took about 6 hours every day to run texpire, which seemed long - but I hadn’t been checking since it had been growing. Well, “notail” sped it up a bit but it still took several hours…. so I got fed up, and with the wireless here, migrated it back to ext3. On ext3? (with dir_index on, data=”ordered”, and commit=60) it took a whopping 12 minuts… or a 40:1 improvement.

There was planned downtime this weekend. The server now has mirrored hard drives, using the software RAID1 driver. And a hopefully much faster news spool on its own partitition, but that is a separate issue most of you are unlikely to see (if you actually know me in person and don’t already have one, do feel free to ask for an account…)
