Hi Scott
This refers to the file system format which is independent of the NSD version
number. File systems can be upgraded but all the NSDs are still at V1. For
instance, here is an NSD I know is still V1:
[root@gpfs2-gpfs01 ~]# grep msa0319VOL2 volmaps
msa0319VOL2 mpathel (3600c0ff0001497e259ebac5001000000) dm-19 14T sdad
0[active][ready] sdft 1[active][ready] sdam 2[active][ready] sdgc
3[active][ready]
[root@gpfs2-gpfs01 ~]# mmfsadm test readdescraw /dev/dm-19 | grep " original
format"
original format version 1001, cur version 1600 (mgr 1600, helper 1600,
mnode 1600)
The file system version is current however.

Subject: [EXTERNAL] Re: [gpfsug-discuss] NSD V2 vs V1 - how can you tell?
# mmfsadm test readdescraw /dev/dm-14 | grep " original format"
original format version 1600, cur version 1700 (mgr 1700, helper 1700,
mnode 1700)
The harder part is what version number = v2 and what matches version 1. The
real answer is there is not a simple one, it is not really v1 vs v2 it is what
feature you are interested in. Just one small example
4K Disk SECTOR support started in 1403
Dynamically enabling quotas started in 1404
