GET_REPAIR failed because of invalid signature

The audit can be affected by GET_AUDIT and GET_REPAIR in three ways:

  1. data is deleted
  2. 3x 5-minutes timeouts for the same piece
  3. data is corrupted.

The first one is visible in the logs as “file not found”. The second is visible too - you should measure time between “download started” and “downloaded” (see Got Disqualified from saltlake - #97 by Alexey). The third one cannot be visible in the logs (it will be downloaded as usual), but sometimes visible, see [storagenode] pieces error: PieceHeader framing field claims impossible size of XXX bytes · Issue #4194 · storj/storj · GitHub
