Working with RAIDs with Parity Delays


R-Studio allows you to create RAIDs with parity delays (any level that allows that). For example, let us create a RAID 5 the parity delays with the following layout:

Three disks,

Delay=16

Block size: 16 KB

Offset: 1088 sectors (544 KB)

Block order: Left Asynchronous (Continuous)

Block order table:

To create such RAID 5,

1 Click the Create virtual volume sets or RAIDs button and select Create Virtual Block RAID & Autodetect

or select Create Virtual Block RAID & Autodetect on the Create menu

Check that the Apply changes immediately check box is clear on the Parents tab. This will prevent R-Studio from trying to start processing the RAID configuration until you specify it completely.

2 Drug the required objects from the Drives pane to the Parents tab and select RAID 5 on the RAID type

Click to expand/collapse Other ways to add objects

These objects may be hard drives, logical disks, or images . Check that the objects are correctly placed.

Note: Objects should be placed in the same order as they were in the original RAID 5. If this order is incorrect, you must change it by dragging the parents to place them in the correct order.

Object control buttons

3 Specify the Block size and Offset parameters on the Parents tab

Disregard the Block order field.

4 Specify the parity delay number in the Parity delay control on the Parents tab.

The number of rows will change to 48.

5 Select Left Asynchronous (Continuous) on the Block Order Field and click the Apply button on the Parents tab
> The created Virtual Block RAID 1 object can now be processed like regular drives/volumes

If R-Studio detects a valid file system on this RAID object, a partition object will appear on the Drives panel.

The Description Files for RAID Configurations topic shows the RAID description file for this RAID configuration.

You also may check the RAID consistency, if necessary. See the Checking RAID Consistency help page for details.
