TECHNIQUES FOR ERROR HANDLING IN PARALLEL SPLITTING OF STORAGE COMMANDS

摘要

Various embodiments are generally directed to techniques for handling errors affecting the at least partially parallel performance of data access commands between nodes of a storage cluster system. An apparatus may include a processor component of a first node, an access component to perform a command received from a client device via a network to alter client device data stored in a first storage device coupled to the first node, a replication component to transmit a replica of the command to a second node via the network to enable performance of the replica by the second node at least partially in parallel, an error component to retry transmission of the replica based on a failure indicated by the second node and a status component to select a status indication to transmit to the client device based on the indication of failure and results of retrial of transmission of the replica.

主权项

1. A method comprising:
performing a command, received from a client device via a network, to alter client data stored in a first storage device associated with a first node; transmitting a replica of the command to a second node via the network to enable performance of the replica by the second node at least partially in parallel with the command; retrying transmission of the replica based upon a failure indication, of a failure, by the second node; and selecting a status indication of performance of the command to transmit to the client device based upon the failure indication and a result of retrying transmission of the replica, wherein the status indication is selected as an indication of retrial of the command as currently under way based upon a determination that the failure is a short-term failure and a predetermined status time period elapsing during retrial of the transmission of the replica.
