Running but corrupted emonpi

Is this an EmonPi, or a raspberry Pi running Emoncms?

Either way, stop using it - you are only making the data corruption worse.

Get a new SD card and put the new image on it (or buy one ready to go from the shop).

If you do not have a Micro SD card to USB reader, get one. There is a USB import script that will work if the card is not too damaged.
