I know there are a few debates about SD card corruption, but nothing is good enough for me.
In the beginning there was no problem with the SD cards, but lately it happened a lot after power failure.
Is there any way to reduce that?
What exactly is the cause of that problem? Is there any data to check, what destroys the SD card? It is interesting, because a lot of things are OK, but there is no way to read
/var/, and the
/etc/ssh directory is empty.
There is a python application that receives a lot of messages. Maybe less logging to the FS from the application? In the beginning there was less of the logging.
One possible solution is a UPS, but problem is, that it is sometimes necessary to unplug the power to restart device.
Is there a device, that can signal the Raspberry Pi to gracefully shutdown?
