Explanation: Datastores are logical containers that are used to store virtual machine files such as virtual disks, snapshots, and templates. These datastores are created on physical storage devices such as SAN, NAS, or local disk.
When a datastore is running low on free space, it can be expanded to increase its capacity. However, before increasing the capacity of a datastore, it is important to ensure that the backing device has enough free space to accommodate the new capacity.
If the backing device for the datastore does not have enough free space, increasing the datastore capacity will fail. This is because the backing device needs to have enough space to allocate new blocks for the expanded datastore.
Therefore, it is important to check the free space on the backing device before increasing the datastore capacity. In addition, it is also recommended to ensure that there are no powered-on virtual machines on the datastore to prevent any potential issues during the expansion process. However, this is not a strict prerequisite for increasing datastore capacity.
