Gauges not being displayed correctly on website

[Safety]

Sorry to say, shorty after i sent my replay the gauge web page status displayed station was off-line, when i looked i found it was.
checking the realtimegauges.json file on the website i noticed that it was 0 bytes. Restarted my pi it fired up ok, however after hitting the internet tab on Cumulus MX the attached error code was displayed.

That appears to be a permissions error; Cumulus is no longer permitted to write to its files. Has the device been mounted read only for some reason?

[Safety]

So i have an idea what to check for regarding your comment "Has the device been mounted read only for some reason?" what would you like me to look at, as I have done no deliberate action regarding "Read only".

[steve]

Could you please check whether the device /media/USB/ has been mounted read-only?

Update:
The issue appears to be that the USB stick is becoming corrupted.
This has now happened on 2 occasions on the last one it lasted around about 8 hours before becoming corrupted.
You can fix the problem by scan an repair. I am going to replace the USB stick and retest

[steve]

I think that if a filesystem has errors, it gets mounted read-only, which explains the error message. USB sticks have a limited life, some as low as 10,000 writes. With Cumulus writing to it every few seconds, it's only going to last a few hours.

Now that is interesting about the life issue, what have you been using to store data when you have been using your Pi?

[steve]

I'm using an SD card. I've been expecting it to die at any moment, but it keeps going. It'll probably die now...

If I ever manage to switch my live system over to the Pi, I'll be using a USB hard drive.

Thank you for the feedback

A good solution might be a solid state SSD drive (Regular 2.5" form factor hooked up via USB). They are made to have many more write cycles than standard USB and SD cards. A small 64gb model can be had for $50 USD or so now. They use much less power than traditional drives, so it would keep with the lower power theme if you're offloading from a PC to a Pi. If you do go go the USB Hard Drive route, I recommend finding the small possible size, 320gb or 500gb, as they will most likely be single platter drives, drawing less power and a higher MTF.

Once I get my Pi going I will have it mount a Folder on my Desktop system in fstab / cifs, and have a cron job set to copy the files over every few days to a folder for backup.
