The sda3 is having 247.80g of unused space and I would like to return this space to the datastore of the ESXi host.
Base on my understanding, I would have to:
1) Reduce the size of the sda3
2) Then somehow reduce the size of the sda
3) Then resize the provisioned space to this VM
I don'y know how to do 1 and 2.
Could someone please help?

Thank you,2016-11-02 10_41_12 - PuTTY.png
