Finding RAID Parameters


R‑Studio for Linux can find parameters for RAID 5 and 6. RAID parameters can be found automatically or manually.

The number of disks in the RAID should be between 3 and 32. RAID parameters can be found only when all original disks (or their images ) are present. Even one substitute object in a RAID (like a missing disk) makes finding RAID parameters impossible.

To find RAID parameters automatically,

1 Click the Auto Detect button on the Parents tab
> R‑Studio for Linux will start searching for the RAID parameters and show the most probable one on the RAID Parameter Detection dialog box

2 Click the Apply button and R‑Studio for Linux will change the RAID layout to the selected one on the Parents tab.
3 Click the Apply button on the Parents tab
> R‑Studio for Linux will use the found parameters for the RAID.

If necessary, you may return to the RAID Parameter Detection dialog box by clicking the Choose Variants button, and select another RAID layout.

To find RAID parameters manually,

1 Click the drop-down Auto Detect list on the Parents tab and select Advanced Detection .
2 Specify the necessary detection parameters on the RAID Parameter Detection dialog box and click the Start detection button

You may change the disk order, offset for disk(s), and enable/​disable disks.

Max offset:

The area on the disk to find RAID parameters in.

Cumulative parameters that estimates the probability of certain found RAID parameters. Moving it to the right increases accuracy but slows the process. Moving it to the left reduces the accuracy but makes the process faster.

3 Select an offset and click the Click here to find RAID Layouts button on the Raid Parameters Detection dialog box

You may add your own RAID offsets. Right-click empty space on the Found offsets pane and select Add Custom offset on the context menu and specify the offset individually for every disk.

4 Select a RAID variant on the Found RAID layouts pane and click the Apply button
5 Click the Apply button on the Parents tab
> R‑Studio for Linux will use the found parameters for the RAID.

If necessary, you may return to the RAID Parameter Detection dialog box by clicking the Choose Variants button, and select another RAID layout.
