[LU-11916] LSOM: lazy_stat mount option not recognized

• Type: Bug
• Resolution: Won't Fix
• Priority: Minor
• Affects Version/s: Lustre 2.12.0
• Environment: CentOS 7.6, MOFED 4.5
• Severity: 3

Description

I was trying to use "LSOM enforced" on a 2.12 client (for testing purpose, not very important), and noticed the lazy_stat option doesn't seem to work:

[794713.969118] LustreError: 152-6: Unknown option 'lazy_stat', won't mount.

This new mount option was mentioned in Li Xi's presentation at LUG'18 (page 7) http://cdn.opensfs.org/wp-content/uploads/2018/04/Xi-Lazy_Size_on_MDS_DDN.pdf

Is there a way to enforce LSOM on a Lustre client, or not yet?
Thanks!
Stephane
