[gpfsug-discuss] mmfind -ls and so forth

[Buterbaugh, Kevin L]

Hi Marc,

I test in production … just kidding.  But - not kidding - I did read the entire mmfind.README, compiled the binary as described therein, and read the output of “mmfind -h”.

But what I forgot was that when you run a bash shell script with “bash -x” it doesn’t show you the redirection you did to a file … and since the mmfind ran for ~5 days, including over a weekend, and including Monday which I took off from work to have our 16 1/2 year old Siberian Husky put to sleep, I simply forgot that in the script itself I had redirected the output to a file.  Stupid of me, I know, but unlike Delusional Donald, I’ll admit my stupid mistakes.

Thanks, and sorry.  I will try the mmfind as you suggested in your previous response the next time I need to run one to see if that significantly improves the performance…

Kevin

Did you read the mmfind.README ?

It mentions...that this sample utility "some user assembly required..."  ...

mmfindUtil_processOutputFile.c
  A utility to parse the "list file" produced by mmapplypolicy and to print
    it in a find-compatible format
  mmfind invokes it once mmapplypolicy begins to populate the "list file"

mmfindUtil_processOutputFile.sampleMakefile
  copy to 'makefile', modify as needed, and run 'make' to compile mmfindUtil_processOutputFile.c
  This should produce a binary called mmfindUtil_processOutputFile
  mmfind will not be able to run until this utility has been compiled
  on the node from which you launch mmfind.

Works for me...
