Thanks JAB and Luis
I know, there are mmdelnsd, mmdeldisk, mmrestripefs and a few other
correlated mm* commands. They are very high-level in work in bulk
discreet fashion (I mean, considering the number of NSDs we have, each
deletion will shave 4% of the storage at once, that is too much).
Then you are goosed. An NSD cannot be changed in size once created and
can only ever be in a file system or out a file system. The only way to
change the size of a GPFS file system is by adding or removing NSD's.
I am not a fan of how the DSS-G creates small numbers of huge NSD's. In
fact the script sucks a *lot* from a systems admin perspective. Then
again someone at IBM thought redeploying your entire OS every time you
want to make a point release upgrade was a good idea.
