Retry Related Options: retry_error=value The error code to retry. retry_delay=value The retry delay. (Def: 5) retry_limit=value The retry limit. (Def: 60) Error Strings Accepted: EIO (5), ENXIO (6), EBUSY (16), ENODEV (19), ESTALE (151) OR retry_error='*' or -1 to retry all errors. OR for Windows: Error Strings Accepted: ERROR_UNEXP_NET_ERR (59), ERROR_NETNAME_DELETED (64) ERROR_BUSY (170), ERROR_SEM_TIMEOUT (121) ERROR_VC_DISCONNECTED (240), ERROR_IO_DEVICE (1117) OR retry_error='*' or -1 to retry all errors.Please Note: The retry limit is per pass. The main IO loop uses an error limit, specified via errors=value, to control the maximum tolerated errors. When retries is enabled, the error limit will get set to the retry limit (if currently less than the retry limit). But that said, if you have long running tests, you will need to specify a higher error limit to keep running when the retry limit is reached.
