Something I wish IBM would address, I’d love to change the block size of some of my file system too.

However, our existing block size on our projects filesystem is 1M and in order to extract as much performance out of ESS we would like its filesystem created with larger block size. Besides rsync do you have any suggestions of how to do this without downtime and in fastest way possible? _______________________________________________ gpfsug-discuss mailing list gpfsug-discuss at spectrumscale.org http://gpfsug.org/mailman/listinfo/gpfsug-discuss
