Because all data, metadata, and parity information is distributed across all nodes, the cluster does not require a dedicated parity node or drive. Note: The isi_for_array command runs the command on all of the nodes. While there is a device failure on a cluster, only the FlexProtect (or FlexProtectLin) job is allowed to run. Director of Engineering - Foundation Engineering. File filtering enables you to allow or deny file writes based on file type. This phase scans the OneFS LIN tree to addresses the drive scan limitations. Isilon job engine is written in a way to give top most priority to Data Integrity and hence when a drive or a node is in Smartfail status OneFS would run FlexProtect and reprotect data.
