[gpfsug-discuss] default value of SIZE in EXTERNAL POOL and EXTERNAL LIST rule

[IBM Spectrum Scale]

Hi shao feng,

It is controlled by -B option.

-B MaxFiles
         Specifies how many files are passed for each invocation
         of the EXEC script. The default value is 100.

         If the number of files exceeds the value specified for
         MaxFiles, mmapplypolicy invokes the external
         program multiple times.

         For more information about file list records, refer to
         the IBM Spectrum Scale: Administration Guide.

Hello,

What is the default value of SIZE in EXTERNAL POOL in filesystem policy?

The document did not mention that, but I found it is not infinity if not
specified.

Thank you!

SIZE sum-number
Is an optional clause of the EXTERNAL POOL and EXTERNAL LIST rules.
sum-number limits the total number of bytes in all of the files named in
each list of files passed to your EXEC 'script'. If a single file is larger
than sum-number, it is passed to your EXEC 'script' as the only entry in a
“singleton” file list.


Specify sum-number as a numeric constant or a floating-point value.


                                                                                                                                       
 Note: The value of sum-number is in kilobytes.
