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.
