If this is functionality you need documenting with AWS is likely the first
step. They may find the value in providing robinhood functionality for you and
others.

Subject: [EXTERNAL] [lustre-discuss] AWS's FSX-Lustre - Robinhood & MDT
Registration
I'm using AWS's FSX's Lustre and am having issues enabling HSM and the
changelog settings:
# lctl set_param mdt.64rczbev-MDT0000.hsm_control=enabled
error: set_param: param_path
'mdt/64rczbev-MDT0000/hsm_control': No such file or directory
As best as I can tell the MDTs don't exist or aren't visible. I'm trying to
figure out if it's a PBKEC or AWS blocks this.
# lctl list_param \*.64rczbev-MDT0000\*
mdc.64rczbev-MDT0000-mdc-ffff888007eef000
Normally I'd ask AWS's support but it's a personal project and that's $$$.
