File an RFE against Scale and I will route it to the right place.

Hi All,

I was able to navigate down thru IBM’s website and find the GPFS 5.0.1 manuals 
but they contain the same typo, which Pete has correctly identified … and I 
have confirmed that his solution works.

Thanks...

Hi Kevin,

I'm running policy migrations on Spectrum Scale 4.2.3, but I use mmapplypolicy 
to kick off the policy runs, not mmstartpolicy. Docs here (which I admit are 
not for your version of Spectrum Scale) state that mmstartpolicy is for 
internal GPFS use only: 
https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.ibm.com%2Fdeveloperworks%2Fcommunity%2Fwikis%2Fhome%3Flang%3Den%23!%2Fwiki%2FGeneral%2BParallel%2BFile%2BSystem%2B(GPFS)%2Fpage%2FUsing%2BPoliciesdata=02%7C01%7CKevin.Buterbaugh%40vanderbilt.edu%7C806e69ddb2294dbe5ad008d5fc5b2e70%7Cba5a7f39e3be4ab3b45067fa80faecad%7C0%7C0%7C636692390912985631sdata=4PmYIvmKenhqtLRVhusaQpWHAjGcd6YFMkb5nMa%2Bwuw%3Dreserved=0

So if the above link is correct, I'd recommend switching to using 
mmapplypolicy, which handily comes with a man page, whereas mmstartpolicy 
doesn't and might have you fumbling around in the dark.

As for the issue you're experiencing with adding a callback, it looks like the 
mmaddcallback command is catching the --single-instance flag as an argument for 
it, not as a parameter for the mmstartpolicy command. After looking at the 
documentation you've referenced, I suspect that there's a typo/omission in the 
command and it should have a trailing double quote (") on the end of the parms 
argument list, i.e.:

mmaddcallback MIGRATION --command /usr/lpp/mmfs/bin/mmstartpolicy --event 
lowDiskSpace --parms "%eventName %fsName --single-instance"

I'm not sure how we go about asking IBM to correct their documentation, but 
expect someone in the user group will have some idea.

Hi All,

So I?m _still_ reading about and testing various policies for file placement 
and migration on our test cluster (which is now running GPFS 5).

On page 392 of the GPFS 5.0.0 Administration Guide it says:


To add a callback, run this command. The following command is on one line:

mmaddcallback MIGRATION --command /usr/lpp/mmfs/bin/mmstartpolicy --event 
lowDiskSpace --parms "%eventName %fsName --single-instance


The --single-instance flag is required to avoid running multiple migrations on 
the file system at the same time.

However, trying to issue that command gives:

mmaddcallback: Incorrect option: --single-instance

And the man page for mmaddcallback doesn?t mention it or anything similar to 
it.  Now my test cluster is running GPFS 5.0.1.1, so is this something that was 
added in GPFS 5.0.0 and then subsequently removed?

I can?t find the GPFS 5.0.1 Administration Guide with a Google search.

Thanks?

Kevin
