+Safe, sanitized Bash examples for planning and executing a GPFS / IBM Spectrum Scale filesystem expansion. The scripts are written as readable operational examples for a Linux Infrastructure Engineer: conservative defaults, clear validation, dry-run behavior, and explicit operator confirmation before changes.
 
 These scripts are examples. Exact GPFS commands, flags, quorum practices, failure-group design, and storage naming standards vary by Spectrum Scale version and site policy.
