[LU-15910] ROOT default LMV is not working for subdirectory mount

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.16.0
• Labels: MON
• Severity: 3
• Assignee: Lai Siyao

Description

In subdirectory mount, the filesystem-wide default LMV doesn't take effect. There are two things need to be done:

1. enforce the filesystem-wide default LMV on subdirectory mount if it's not set separately.
2. "lfs getdirstripe -D <subdir_mount>" should print the filesystem-wide default LMV.
