meteohub.de

suddenly i noticed that my weather-data was not being updated.

i checked the meteohub but it wasn't accessible with its normal ip. so i checked the dhcp-list and the ip changed (allthough the ip was set to 'fixed' in meteohub)

trying to access the webpage on it failed... so i ssh'ed to it. the passwd was still meteohub so i thought everything was fine, but the output of ps and ls gave me something not quite 'meteohub-like':

the hostname had changed and none of the meteohub stuff was running. i gave a reboot and it came back to this state.

i had it before and only a hard reset (turn off/on) fixed it, so i'll try that tomorrow (i'm not at home right now). did anyone notice this as well?

the ps output and command line prompt indicate that Meteohub was not able to boot the USB stick.

Boot process is done in two steps. Step 1 is booting the limited SlugOS from NSLU2 firmware, then full-fletched Meteohub is booted from USB stick. For some reason the system does not do the second step. I had this once with a certain USB stick. After working some while this USB stick could not be started (just on every second attempt) for sure. Changin the stick solved this.

ok, but the strange thing is... i didn't reboot the nslu2 for this situation to happen. it just got into this mode...

and a few software-reboots didn't fix anything, only a hard reboot (turning it on/off) :dry:
