What happens when the Thin Provisioning property is set for a LUN?
A.
This property allows the volume size to exceed the amount of available space.
B.
A share reserves exactly enough space to completely fill the share.
C.
Thin provisioning allows the storage administrator to divide the pool capacity into evenly sized LUNs.
D.
A ZFS file system is created by setting a quota and reservation to the same value.
Explanation:
By default, a LUN reserves exactly enough space to completely fill the volume. This ensures that clients will not get out-of-space errors at inopportune times. This property allows the volume size to exceed the amount of available space. When set, the LUN will consume only the space that has been written to the LUN. While this allows for thin provisioning of LUNs, most filesystems do not expect to get “out of space” from underlying devices, and if the share runs out of space, it may cause instability and/or data corruption on clients.
