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

[Felipe Knop]

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)

  Felipe

It had better work — I’m literally going to be doing exactly the same thing
in two weeks…

      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.
