Abstract
Embodiments of the disclosure provide techniques for updating a distributed transaction log on a previously offline resource object component using distributed transaction logs from active host computer nodes from separate RAID mirror configurations. Each component object maintains a journal (log) where distributed transactions are recorded. If a component object goes offline and subsequently returns (e.g., if the node hosting the component object reboots), the component object is marked as stale. To return the component object to an active state, a distributed resources module retrieves the journals from other resource component objects from other RAID configurations where the data is mirrored. The module filters corresponding data that is missing in the journal of the previously offline corresponding object and merges the filtered data to the journal.
