[LU-19506] Nodemap: duplicate filesets should not be added on the same hierarchy

• Type: Bug
• Resolution: Unresolved
• Priority: Medium
• Affects Version/s: Lustre 2.17.0
• Severity: 3
• Assignee: Marc Vef
• Reporter: Marc Vef

Description

Currently, multiple filesets can be configured that share the same directory hierarchy, e.g.,

1. "/dir"
2. "/dir/subdir" 

2 should be treated as a duplicate and not be added unless 2 is set as a read-only fileset since it adds an additional restriction to the fileset.
