[gpfsug-discuss] Checking if a AFM-managed file is still inflight

Information reported by that command (both at cache and home side) are size, blocks, block size, and times.
I think it cannot be enough to decide that AFM completed the transfer of a file.
Did I possibly miss something else ?
It would be nice to have a flag (like that one reported by the policy, flags “P” – managed by AFM – and “w” – beeing transferred -) that can help us to know if AFM considers the file synced to home or not yet.

Dear GPFS users,

I know that through a policy one can know if a file is still being transferred from the cache to your home by AFM.



I wonder if there is another method @cache or @home side, faster and less invasive (a policy, as far as I know, can put some pressure on the system when there are many files).

I quickly checked mmlsattr that seems not to be AFM-aware (but there is a flags field that can show several things, like compression status, archive, etc).



Any suggestion ?



Thanks in advance,



   Alvise
