Expand the Size of a LUN
After you create a LUN, you cannot change the provision setting (thin or thick), but you can
expand the size of the LUN.
Expansion is instant, regardless of the data size, but you must first disconnect all users that
are connected to the LUN. Disconnect access to the LUN by removing the LUN from the LUN
group to which the users have access (see
Create a LUN Group on page 103).
Note: On ReadyNAS 102, 104, and 2120 systems, individual LUNs cannot
exceed 8 TB.
To expand the size of a LUN:
1. Select Shares > Shares.
A list of shared folders and LUNs on each volume displays.
2. Select the LUN that you want to expand.
