Failed to migrate v0 piece. Piece may not be recoverable

And now this error pops up on the logs, running 1.96.6
Any thoughts?

Have you tried to search the log for that piece ID ?

Unfortunately this is mean two things: either these pieces are corrupted, or lost.
The outcome is the same - your node likely failed this audit.

I haven´t. I don´t even know how…I almost don´t interfere with it.

The next line after migrate would be failed to delete piece with a reason. Most likely it says file does not exist. You can search the log based off of the piece id in this line. Its just a warning so you can ignore it. The piece’s entry will be deleted from the database.

I have encountered migrate warning during piece deletion.

WARN	pieces	failed to migrate v0 piece. Piece may not be recoverable	{"process": "storagenode"}
WARN	retain	failed to delete piece	{"process": "storagenode", "Satellite ID":

Oh, then it’s better. The piece should be deleted anyway. I immediately thought that it’s during audit.
