It New or replaced drives are automatically added to the WDL as part of new allocations. I guess it then will have to rebuild all the data that was on the disk. The job engine coordinator notices that the group change includes a newly-smart-failed device and then initiates a FlexProtect job in response. FlexProtect and FlexProtectLin continue to run even if there are failed devices. The successfully repaired nodes and drives that were marked restripe from at the beginning of phase 1 are removed from the cluster in this phase. In both clusters, the old NL400 36TB nodes were replaced with 72TB NL410 nodes with some SSD capacity. OneFS enables you to modify the requested protection in real time while clients are reading and writing data on the cluster.
