User Manual

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 92).
On ReadyNAS 102, 104, 202, 204, 212, 214, and 2120 systems, individual LUNs
cannot exceed 8 TB.
Note
File systems inside the LUN are not expanded by this procedure. After expanding the
LUN, you can expand the file systems from the iSCSI initiator.
Note
To expand the size of a LUN:
1. Log in to your ReadyNAS.
2. Select iSCSI.
The screen updates showing the iSCSI LUNs and groups.
3. Select the LUN.
4. In the pop-up menu, click the Settings button.
The LUN settings display in a pop-up window.
