AWS parallelcluster documentation change

Service: parallelcluster · 2026-06-04 · Documentation low

File: parallelcluster/latest/ug/SharedStorage-v3.md

Summary

Updated default EBS volume size from 35 GiB to 40 GiB, fixed grammatical errors in DeletionPolicy descriptions, and corrected security group phrasing from 'associated to' to 'associated with' across multiple filesystems

Security assessment

Changes involve grammatical corrections and default value updates without addressing vulnerabilities. The security group port requirements remain unchanged; only phrasing was improved for clarity.
