Problem with the SD card

2 years 8 months ago #2119 by hjfabius
Hi,
I've strange situation that I really don't know how to solve it.
I've installed EasyIot on a raspberry using the standard SD image.
Raspberry reboot every night to keep it stable.
Worked fine for almost 1 month with several MySensors nodes. B)

Couple of weeks ago I noted not to see any more updates in the summary page while it was ok in the trend charts. :ohmy:

I checked on the DB and the data were there. I then checked the XML file and I noted that latest update was very old. :blink:

I basically stopped the service, copy the XML files, delete the old ones and move back the copied one. Reboot the service and eveything was ok. Home page start to be refreshed without any problem. :woohoo:
I suspect the old file was in a way corrupted.

Few days ago I had again the same problem. :S
I applied the same tecnique and I solved again.

I somehow believe that it's related to the fact that SD have a limited number of Write capability. If I understood correctly basically this file is rewritten everytime a sensor send a new file.

Anyone experienced the same probelm?
Have the installation on an external drive can solve the problem?
Do you have any idea like for example move the xml in a ram drive?

Best regards
hjfabius

I think you have right with the sd card.
Iam thinke i like to trye to use a bananapi it has esata driver support, the i just will use the sdcard to boot the system on, and the let the rest run on the harddisk.

Use good quality SD card and good quality power supply. Mine works more than a year without problems.
