QTS creates the new RAID group and then the RAID group starts rebuilding. The capacity of the new RAID
group appears as free space in the storage pool after RAID rebuilding is completed.
Volume Management
Expanding a volume increases its maximum size, also known as its capacity, enabling it to store more data.
Expansion should be performed when free space is low, to prevent users suddenly discovering that they are
unable to save files to the volume.
Expanding a Thick or Thin Volume
Thick and thin volumes can be expanded online, meaning that space can be added to the volume while it is
still being accessed. The extra space is allocated from the volumes parent storage pool.
Volume Type Maximum Allowed Expansion
Thick Amount of free space in the parent storage pool.
Thin Twenty times the amount of free space in the parent storage pool
Important
Setting the maximum size of a thin volume to a value that
is greater than the amount of free space in the storage
pool is called over-allocation.
