ReadyNAS OS 6.7 (Continued) Item Compression Provision Size Description Select the Compression check box to enable data compression. Compression saves storage space and increases the speed of data transfers, but the compression and decompression processes require additional resources. By default, the Compression check box is cleared. Compression can be set or turned off only when the LUN is created. The provision setting is provided for information only. You cannot change the provision setting of an existing LUN. For information about how to expand the size of an existing LUN, see Expand the Size of a LUN on page 83. 6. Click the Apply button. 7. Click the OK button. Your settings are saved and the window closes. For information about how to set access right for a LUN, see LUN Groups and Access Rights on page 86. For more information about snapshots, see Chapter 5, Snapshots on page 104 . 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 86). Note 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. 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. LUNs 83
