[gpfsug-discuss] Dry-Run functionality

[Jez Tucker]

Hello all,

   I wonder if you could have your take on your ideal dry-run functionality.

Post London User Group, we had much feedback regarding the need for 
dry-run functionality.
Therefore we have implemented dry-run functionality for our GPFS/Scale 
Python API across all calls.

API calls for Policies have the ability to run in 'test' or 'run' mode.  
(ref: man mmapplypolicy)

How would you expect to use dry-run functionality on a policy?
We have our own opinion, but we'd like to hear yours.

1) Validate the policy and print the policy content to stdout/other.  No 
mmapplypolicy is performed.
2) Validate the policy and enforce mmapplypolicy with -I test
3) Return what would be called.  E.G. mmapplypolicy -P mypol.pol --flag1 
--flag2 --etc
4) Other

Best regards,

Jez
