kos-mos is dead, meet t-elos

The old file server was a beast. 2 2.4GHz dual-core Opterons, the old 90nm chips. 5GB (don’t ask) of RAM. And…2.7TB of storage, with a big pile of 250GB and 500GB drives mashed together into several arrays that were dumped into a volume group. The whole thing was encrypted just for kicks. There was also [...]

ISA is not fast

Using a pair of ISA IDE controllers for a mirror, and an ISA NIC is a recipe for sloooooow. md2 : active raid1 sda3[2] sdb3[1] 425600 blocks [2/1] [_U] [====>................] recovery = 24.3% (104064/425600) finish=10.5min speed=508K/sec Oh yeah.

Building the airplane: engines

With a new display for my main workspace upstairs, I now have three identical displays for use building my flight sim machine! Things have shifted around a bit hardware wise since the last time I attempted this. Then, I used a single dual-core system (Athlon 64 X2 4400+) with two Nvidia 7800GT cards to drive [...]

kos-mos is healthy again

With the receipt of a replacement drive that took about a year for me to send back for warranty repair, all the RAIDs in kos-mos are rebuilt and happy now. Seagate sent a 400GB model to replace the 250GB I sent out. Doesn’t gain me anything really since I don’t have any other 400GB drives. [...]

HPT-366 finale: giving up.

Yeah, I’m a quitter. After having some more interrupt issues with the HPT-366 IDE controller in the old file server, this morning I decided to make another effort to get to the bottom of it. The issues I was having seemed to coincide with the tulip ethernet driver reporting various problems. First on the list, [...]

Automatic notification of Debian package updates via cron

Very simple, and hinted at in the Debian APT HOWTO. I think I used to use a different package for this, but I think I like the simplicity of this method better. After installing apt-show-versions, I made the following entry in root’s crontab: @daily apt-get -q -q update 2> /dev/null && apt-show-versions -u root gets [...]
