World cup database another error on BASH terminal

Until you guys/gals get sick of me, I will continue to report these errors. This is day 3 of errors.

BASH terminal:
PANIC: could not fdatasync file “000000010000000000000001”: Input/output error
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
connection to server was lost
