Abstract
Various systems and methods for performing Input/Output (I/O) quiesce and drain operations in multi-node distributed storage systems are disclosed. For example, one method involves receiving a message. The message indicates a request for a operation to be performed by a node, where the node can receive I/O requests from an application, as well as remote I/O requests from another node. The node can issue the I/O requests and the remote I/O requests to the one or more storage devices. In response to receipt of the message, the method performs a first portion of a operation on the node. The first portion of the operation includes the node not processing any additional locally generated I/O requests and processing additional remote I/O requests.
