Kevin, The improved rebalance function (mmrestripefs -b) only depends on the cluster level being (at least) 5.0.0, and will work with older file system formats as well. This particular improvement did not require a change in the format/structure of the file system.

Sent by: [email protected] Simon in correct … I’d love to be able to support a larger block size for my users who have sane workflows while still not wasting a ton of space for the biomedical folks…. ;-) A question … will the new, much improved, much faster mmrestripefs that was touted at SC17 require a filesystem that was created with GPFS / Tiger Shark / Spectrum Scale / Multi-media filesystem (<grin>) version 5 or simply one that has been “upgraded” to that format?
