[gpfsug-discuss] mmchconfig release=LATEST mmchfs FileSystem -V full

[Sergi More]

Hi Juanma,

Yes, it is safe. We have done it several times. AFAIK it doesn't 
actually change current data and metadata. Just states that filesystem 
is using latest version, so new features can be enabled.

It is something to take into consideration specially when using 
multicluster, or mixing different gpfs versions, as these could 
potentially prevent older nodes to be able to mount the filesystems, but 
this doesn't seem to be your case.

Best regards,
Sergi.
