Unfortunatelly I didn’t find such errors neither on the forum error-codes nor in the support tickets. If it is still possible, could you please post the full error message?
Did you try to use a tool to fix metadata, like here:
or it throws errors during node start?
Also, did you remove hashstore logs or corrupted pieces from blobs?
After what event the corruption is happened? Was there some reboot or shutdown, like a power loss or a system crash?
What was a filesystem?
@elek do you know, if the hashstore log file is corrupted, can we recover readable pieces from it?
Also, how is it possible to get them corrupted during migration?
