Abstract
Techniques for providing a framework for handling execution of HA flows in an active-active storage node configuration. The techniques include receiving notifications of functional statuses of processes and/or equipment associated with storage nodes in the active-active configuration, making determinations regarding how to address HA events occurring on the processes and/or equipment associated with the storage nodes based on the received notifications, and, in response to a request to execute an HA flow for a respective HA event, determining whether to refuse the request to execute the HA flow, service the request to execute the HA flow, abort one or more HA flows in execution, and/or postpone execution of the HA flow to a later time based on one or more dependencies defining conditions for the HA flow. In this way, mutual interference of HA flows or other process threads in the active-active configuration can be reduced or eliminated.
