IBM Spectrum Scale-FPO deployment

This section provides the information for FPO deployment.

Disk-partitioning algorithm
Failure Group selection rules
Failure groups are created based on rack allocation of the nodes. One rack mapping file is supported (Rack Mapping File).
Rack mapping file
Nodes can be defined to belong to racks. For three or more racks, the failure groups of the NSD will correspond to the rack the node is in.
Partitioning function matrix in automatic deployment
Each data disk is divided into two parts. One part is used for an ext4 file system to store the map, or reduce intermediate data, while the other part is used as a data disk in the IBM Spectrum Scale file system. Only the data disks can be partitioned. Meta disks cannot be partitioned.
