Subject: [gpfsug-discuss] mmaddcallback documentation issue
Sent by: [email protected]
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
