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
