Hi all,
i'm a brand new user of 3par system, so, first of all, sorry for the bosh that you read in this topic :D

I have an issue from some days, and i don't understand what is wrong.

I have a Virtual Volume presented on 2 fileserver in cluster, i add a 2,7 Gb iso inside and the SSMC show that the VV is increased properly (as below)
Image

but when i delete the file the VV doesn't decrease, but the file share is empty

Image

\\fileserver\print matches with VV Nasclusterpom27


What i do wrong? What i do for recovery this space?

Thanks a lot in advantage for the help

L :ugeek:

Hello Erbcita,

What version of Windows? Also what version of 3PAR code?

Hi Richard,

3par 3.3.1
The the nodes of the cluster are a Windows server 2019 Standard

During the night a strange thing happened : now the size it's right :roll:
How can this be explained?

Thanks,

L

First, unmap is async. So you will see the free capacity in the host at once, but it will take time before the storage system completes the task.

Secondly, SSMC doesn't constantly update all parameters. If you checked CLI a few minutes later it should be correct..
