Hi, I have exactly the same problem.
The reserved user size is growing more and more.
The used user size comes down by doing the command line
"esxcli -s serverxyz storage vmfs unmap -l 3PAR_VV_LUNxyz"
But the reserved user size comes not down.I did a "compact CPG" and also a "tune system" and I have no errors and enough free space.
Why does it not shrink / can not be reclaimed ?
Is there no cleaning process ?
Has somebody a solution, for that problem ?
Maybe a one way storage by HP... data just grwoth, never deletes...
And, by the way, why are there no automatic storage optimazion tasks - out of the box ?
Thanks a lot
