=>since resize space is counted in allocated space even though it cant be
attach to VM , other storage operation will fail because threshold value
If resize is allowed in volume detach
==============================
1-since there is no check for how much can be increased , suppose user has
resized it to 1000GB
2-when user try to attach volume to vm it will fail since available space is
not sufficient .
3-even though user is not able to use the resized volume ,CS will count 1000GB
in allocated storage .
4-Dash will show allocated percentage >100%
5-Because threshold values , we cant perform any operation to that PS
If resize is allowed online ( volume Attach) state it will fail in first place
and will not cause any problem
