This article details steps necessary to convert from a RAID0 Array configuration to a RAID10 redundant configuration and back again.
Problem
If you did not configure a redundant or parity-redundant drive configuration when your ggRock server was built, your data could be at risk cause by power outages, drive failures, unplanned drive removal, or other issues that could result in data loss. If you wish to convert back, simply reverse the steps.
Solution
RAID0 to RAID10
-
Back up images to prevent data loss. Please refer to "Backing Up Images" for more information.
-
Click the "Array" tab in the menu bar to the left of the ggRock Web UI. Observe the initial RAID0 array configuration containing two (or more) Stripes with only one Drive in each.
-
From the "Array" screen, click the "Array" menu (Three vertical dots) next to "Stripe 1 (SingleDrive)", then click the "+ Add Drive" context menu item.
-
From the "Add Drive" dialog, click the "Add drive to stripe Stripe 1" drop-down, selecting a drive greater than or equal to the size of the current Drive in the Stripe, then click the "Save" button.
-
From the "Array" screen, click the "Array" menu (Three vertical dots) next to "Stripe 2 (SingleDrive)", then click the "+ Add Drive" context menu item.
-
From the "Add Drive" dialog, click the "Add drive to stripe Stripe 2" drop-down, selecting a drive greater than or equal to the size of the current Drive in the Stripe, then click the "Save" button.
RAID10 to RAID0
-

-
Click the "Array" tab in the menu bar to the left of the ggRock Web UI. Observe the initial RAID0 array configuration containing two (or more) Stripes with only one Drive in each.
-
From the "Array" screen, click the "Array" menu (Three vertical dots) next to the Drive you wish to remove from the first Stripe, then click the "Remove Drive" context menu item.
-
From the "Confirm Remove" dialog, place a check next to "Confirm" and click the "Confirm" button to remove the drive from the stripe.
-
From the "Array" screen, click the "Array" menu (Three vertical dots) next to the Drive you wish to remove from the second Stripe, then click the "Remove Drive" context menu item.
-
From the "Confirm Remove" dialog, place a check next to "Confirm" and click the "Confirm" button to remove the drive from the stripe.
Additional Information
To migrate from RAID0 (Single Drive) to RAID10 (Mirrored), you need only add one additional Drive to each Stripe.
To migrate from RAID10 (Mirrored) to RAID0 (Single Drive), you need only remove one Drive from each Stripe.
Currently you can only add Drives of the same size to the Stripes, we are looking for your feedback about changing that to allow mixed-size drives
