| + | === Rebuild a RAID 1 array === | ||
| + | When a drive in a RAID 1 array has failed, rebuilding the data has to be done manually. | ||
| + | |||
| + | - Replace the faulty hard drive. | ||
| + | - Select **Linux Soft RAID** and open the **RAID** tab.\\ {{:applications-diskmanager-12a.png?nolink|}} | ||
| + | - Drag the new drive (the drive with free space) and drop it into the existing RAID array.\\ {{:applications-diskmanager-12b.png?nolink|}} | ||
| + | - Scroll down and click **Rebuild**. This will create a partition identical in size to the existing drive already in the RAID array and start mirroring the data.\\ {{:applications-diskmanager-14a.png?nolink|}} | ||
| + | - Click **Refresh** to update the status and monitor the rebuilding progress.\\ {{:applications-diskmanager-15.png?nolink|}} | ||
| + | - Depending on the capacity of the new drive, you will have some additional free space. If the capacity is identical to the existing drive, the remaining space can be used for SWAP. If the capacity is larger, you can create an additional partition for extra storage. Either way, to make use of this free space, you will have to manually create a partition, format and mount it.\\ {{:applications-diskmanager-16.png?nolink|}} | ||
| + | - Assuming that the capacity of your new drive is identical to the existing drive, we suggest creating a SWAP partition. To do so, select the **Free Space**, open the **Partition** tab and click **Create**. The partition type and size can be left at default.\\ {{:applications-diskmanager-16a.png?nolink|}} | ||
| + | - Select the new partition, name it **SWAP**, select **SWAP** for the file system and click **Format**.\\ {{:applications-diskmanager-17a.png?nolink|}} | ||
| + | - Select the new SWAP partition and click **Mount**.\\ {{:applications-diskmanager-18a.png?nolink|}} | ||
| + | |||
| + | <note>The rebuild process will take a while. Click **Refresh** to update the status and monitor the progress. If the device is turned off, rebuilding will continue as soon as the power is turned on again.</note> | ||
