Hello. In last three or four days I've had a problem with my Meteohub. I noticed that my weather data were strange on my website:
http://www.dolomitilivecam.it/it/meteo- ... m-badia-bz
So I opened my Meteohub's control panel and tried to understand what happened. I rebooted the Raspberry, then clicked on "Weather Station" menu link and tried to set "clear internal recordings and set interval to 5 minutes" on Init Comand.
But after clicking on "Save" I get this red alert message:
Initialization file cannot be opened (/home/meteohub/logger.conf): No space left on device
No space left on device? What? I started to use this meteohub less than one month ago! It's a Raspberry Pi with a 8 GB SD card.
Any suggestion?

Looks like the file system on your SD card is damaged,
which unfortunately happens here and there on the RPI.

Simply: regular backups, new sd-card and new install

Do you know a brand of safe SD Card?
The weather station I'm asking help for is very far apart from here. Can I set all parameters from my home and send a ready SD card to the weather station's owner? And, eventually, how?

Or log in as root, unmount /data, and run fsck against it...
fuser -km /data - will kill all processes using /data
umount /data
fsck /dev/mmcblk0p4
shutdown -r now
A "df" command will show you the utilization of each mounted filesystem, I'm presuming its /data that is having the problem.

Linux has tools like e2fsck for that.

if I do:
Code: Select all
fuser -km /data (will kill all processes using /data)
than
I receive:
Do I assume that there is still something using /data ?

Yeah, fuser will not kill all the processes.
If you have access to the console, I would recommend to go to init 1 (which means no network access), as this will definitely kill things like smb.

Core files to transfer are:
/data/weather/YYYYMM/* for raw weather data
/data/graphs/* for graph definition
/home/meteohub/meteohub.conf for most of config data
/var/cron/tabs/root for the upload/send schedules

The next time my SD card goes bad, I am seriously considering one of these Panasonic "Industrial Grade" SD cards:

The "SLC" (single-level) cards seem to be the best, but they are really expensive. Even the RP-SDPC16 is almost twice what the Rasperry Pi costs.

I found them (16GB) on Mouser (USA), but I switched to Mouser Europe and they seem to have it as well. Price is 57,79 €

Thanks for sharing.
Why would these cards be any better than the normal ones accept for better Low/High temperature environments, can someone confirm thats it is worth the money?
