[gpfsug-discuss] ESS: mmvdisk filesystem with "--version" fails

[Simon Thompson]

Looking in “mmprodname” looks like if you wanted to use 17, it would be 1700 (for 1709 based on what Felipe mentions below).

(I wonder what 99.0.0.0 does …)

Stephen, Bob,

A colleague has suggested that the version number should be of the form (of 4-number) V.R.M.F. I believe two values are available for 4.2.3:
4.2.3.0 and 4.2.3.9

("4.2.3" may not get recognized by the command)

The latter would be recommended since it includes a FS format 'tweak' to allow GPFS to fix a complex deadlock. (I'm searching for a publication on that)

Why doesn’t this work? I want to create a file system with an older version level that my remote cluster running 4.2.3 can use.
