FRITZ!WLAN USB Stick N v2 on openSUSE Leap 42.1

Posted on October 19, 2016 by j mozdzen

I recently had to deal with a freshly bought HP laptop (called “HP 15-BA030NG”), a basically nice piece of hardware, nothing fancy but doing its job under openSUSE Leap 42.1. We moved the laptop to a location where it had to access a 5 GHz WLAN, no 2.4 GHz networks available. To cut the story short: That 2016 hardware comes without 5 GHz support. (HP, are you listening? What a crappy design decision, just to save a few cents!)

SCST dev_vdisk errors

Posted on January 11, 2016 by j mozdzen

Recently, we received reports of SCST-related error messages from one of our SAN servers:
kernel: [1082754.895993] [4821]: dev_vdisk: ***ERROR***: write() returned -28 from 4096

A quick analysis showed that these errors started on a working day right after holiday season, but during the evening hours (so no-one was actively working on-site). From then on, we saw roughly 10 to 30 similar messages per incident, with these incidents occurring 45 to 90 minutes apart. What caught our eye was the fact that these incident were always on a quarter-of-an-hour mark. Continue reading →
