[gpfsug-discuss] asking for your vote for an RFE to support NFS V4.1

[Stijn De Weirdt]

hi malahal,

we already figured that out but were hesitant to share it in case ibm
wanted to remove this loophole.

but can we assume that manuanlly editing the ganesha.conf and pushing it
to ccr is supported?
the config file is heavily edited / rewritten when certain mm commands,
so we want to make sure we can always do this.

it would be even better if the main.conf that is generated/edited by the
ccr commands just had an include statement so we can edit another file
locally instead of doing mmccr magic.
