Thank you. Ill-placed on ESS or COS? I understood restriping was for NSDs,
so that would be on our ESS not COS? The direction I want to move the files
is from COS to ESS. We do not have AFM enabled, we are using TCT.

 "KB_Ill" shows how much data are ill placed or ill replicated.  They can
be resolved by mmrestripefs or mmrestripefile.
Copying to AFM team regarding recall in AFM-COS environment.

Hi all, I need to recall from on-prem COS a folder with subfolders and
files, approximately 4600 files making up 656G. We have a policy that runs
every 30 mins, and I added this line to it:

Hi all,

I need to recall from on-prem COS a folder with subfolders and files,
approximately 4600 files making up 656G.
We have a policy that runs every 30 mins, and I added this line to it:

RULE 'migrate_iac-workspace_Chem-labs' MIGRATE FROM POOl 'migrate' TO POOL
'data' WHERE PATH_NAME LIKE
'/gpfs/nhmfsa/bulk/share/workspace/iac-workspace/Chem_Labs/%'

Migrate is an external pool
RULE EXTERNAL POOL 'migrate' EXEC '/usr/lpp/mmfs/bin/mmcloudgateway files'
OPTS '-F' ESCAPE '% -'

And data is the default placement pool
RULE 'Placement' SET POOL 'data'

When it runs it identifies matching files:
Rule#     Hit_Cnt               KB_Hit                 Chosen
KB_Chosen         KB_Ill    Rule
13          4846                     2491152              4846
2491152              7056      RULE      'migrate_iac-workspace_Chem-labs'
MIGRATE  FROM      POOL  'migrate'  TO  POOL  'data'     WHERE(.)

I can’t find what ‘KB_ Ill’ means but nothing is migrating.

Migrations in other policies work, but this is a ‘recall’ policy.
From this document
https://www.ibm.com/docs/en/spectrum-scale/5.1.3?topic=pools-migrate-recall-external

It suggests it should be invoked as a recall.

Any ideas?

Kindest regards,
Paul
