FATAL: Caught exception: File size is not a multiple of recordSize

[freerko]

Hi,

looks like my VM got rebootet and afterwards Fulcrum doesn't start anymore with the error FATAL: Caught exception: File size is not a multiple of recordSize. Do I have to delete the db folder and sync again from scratch or is there anything else I can try to fix this?

Yeah the db is corrupted. You must now delete the data dir and resynch.

If you have extra diskspace leftover, after a resynch, you can stop fulcrum then take a backup of the datadir. This way you have at least a partially synched Fulcrum datadir backup you can restore from...
