Systems and methods for preventing input/output performance decrease after disk failure in a distributed file system

摘要

In accordance with embodiments of the present disclosure, a method may include receiving from a plurality of data nodes of a distributed file system an indication of whether a fault condition exists with respect to a storage resource of the respective data node. The method may also include receiving an input/output request for a storage resource of a particular data node from a host information handling system communicatively coupled to the distributed file system. The method may further include, responsive to the input/output request, directing the input/output request to the particular data node if no fault condition exists with respect to storage resources of the particular data node and directing the input/output request to another data node of the distributed file system if a fault condition exists with respect to one or more storage resources of the particular data node.

1. A method comprising:
receiving from a plurality of data nodes of a Hadoop distributed file system an indication of whether a fault condition exists with respect to a storage resource of the respective data node; receiving an input/output request for a storage resource of a particular data node from a host information handling system communicatively coupled to the Hadoop distributed file system; and responsive to the input/output request:
directing the input/output request to the particular data node if no fault condition exists with respect to storage resources of the particular data node; anddirecting the input/output request to another data node of the Hadoop distributed file system if a fault condition exists with respect to one or more storage resources of the particular data node.
