[lustre-discuss] [EXTERNAL] AWS's FSX-Lustre - Robinhood & MDT Registration

[Coffman, Chris]

>From what I recall AWS FSx Lustre is a manage service that provides your clients a mounted lustre and zero control over the backend servers. I believe the mdt option you’re attempting to enable requires you be on the MDS node you are not able to access.

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 $$$.
