Looking at:
Code:
clihelp -col showvv
it describes
Quote:
Grown_Usr_MB
Amount of user space that the volume has grown.
Reclaimed_Usr_MB
Amount of user space that the volume has had reclaimed.
This would have to be counters based on VV inception as there is no way to specify a timeframe for a showvv command. I would imagine this command might be useful to gauge how actively a volume grows/shrinks. To put another way, if a volume is only growing and never shrinking, do you want the overhead of having zero detect turned on?
I've never used these values so I am only speculating.
