If a cluster node fails, perform node operating system recovery in a systematic manner to ensure that the node is brought up with the configuration that is consistent with other cluster nodes.
The following sections provide details about operating system recovery and post-recovery configuration that is required to bring the node into an existing Storage Spaces Direct cluster.
The Dell EMC PowerEdge servers offer the Boot Optimized Storage Solution (BOSS) S-1 controller as an efficient and economical way to segregate operating system and data on the internal storage of the server. The BOSS S-1 solution in the latest generation of PowerEdge servers uses one or two BOSS M.2 SATA devices to provide RAID 1 capability for the operating system drive.
Note: All Dell EMC Solutions for Azure Stack HCI are configured with hardware RAID 1 for the operating system drives on BOSS M.2 SATA SSD devices. The steps in this section are required only when recovering a failed cluster node. Before creating a new RAID, the existing or failed RAID must be deleted.
This procedure describes the process of creating operating system volumes.
