Hi all

System: 3PAR 8450 All Flash Array

i have 1 CPG configured which has multiple TPVV presented to a Hyper-V Cluster

Say free space is 50TB

Volume 1 for example is 6TB (5TB Used 1TB free)
Volume 2 for example is 6TB (4TB Used 2TB free)

I have created another Volume 3 which is 6TB and using storage migration move a VM which is 4TB in size from volume 1 to Volume 3

i noticed that the free space decreased by 4TB to 46TB and when i run a compact CPG , the space is still not being reclaimed. How do i get the space from Volume 1 back

Can someone please let me know what i m doing wrong

It takes time.

Review the difference between usr used and usr rsvd on the volumes. The difference between those numbers is the amount of data pending reclaim.
