I am not sure what caused your many error messages. it is complaining that it cannot find the blob and cannot get the progress from database. So there seems to be some issue related to that. And then it cannot perform the write test to the storage directory in 1 minute. So you are having some issue all around this which you need to check 1 by 1.
For check and rebuild database.: Database disk image is malformed error in piece_expiration db - #3 by snorkel
