A shared storage architecture persistently stores database files in non-volatile memories (NVMs) of a plurality of computing nodes of a multi-node DBMS. The computing nodes of the multi-node DBMS store data blocks in NVM and each computing node of the DBMS stores copies of each data block stored on the plurality of computing nodes. A computing node that disconnects and subsequently rejoins the DBMS employs an on-demand approach to resilvering stale data blocks that have been updated in other computing nodes in the DBMS while the computing node was offline. A data block may be resilvered on-demand based on an I/O request for a specific data block from a workload running on the reconnected computing node. Stale data blocks on the reconnected computing node are not resilvered unless they are accessed by the workload.
