Abstract
Example implementations relate to preserving data availability in a constrained deployment of an HA system (e.g., an HA storage system) in the presence of pending faults. According to an example, a first arbiter, acting as a witness to facilitate maintaining quorum for the HA system, and a first node are provided within a first failure domain; and a second arbiter, serving as a backup arbiter, and a second node are provided within a second failure domain. Responsive to receipt of an indication of a pending fault impacting the first failure domain by a member of the current configuration of the HA system, establishment of a new configuration, excluding the first arbiter and including the second arbiter, is initiated. Responsive to a majority of the current configuration installing the new configuration, the second arbiter is enabled to serve as the active arbiter by transferring state information to the second arbiter.
