 +====== Repairing RAID Configurations ======
 +
 +You may need to recreate the Mirrored and/or RAID 5 volumes if a disk should fail. \\ 
 +
 +<note important>​**Important info:** In the event that an individual hard disk fails in the 5big Office/​Office+,​ contact your LaCie reseller or LaCie Customer Support for technical assistance. If the problem drive was purchased from LaCie and it is within the warranty period, please replace it with a hard drive provided by LaCie. LaCie will not replace a non-LaCie hard drive or any hard drive purchased from a third party. Please note that the replacement disk capacity should be equal to the original disk. While you may use a disk with more capacity, RAID configurations only recognize the size of the original disk.</​note>​

 +
 +===== Repairing the Mirrored and RAID 5 Volumes After a Disk Failure =====
 +
 +The steps below will illustrate how to repair Mirrored and RAID 5 volumes following disk failure. Partitions from the failed hard drive, Disk 1, had been tied to each volume. \\ \\ 
 +
 +Use Disk Management to repair or change RAID configurations in Windows:
 +  - Launch the Dashboard from a Windows workstation on the same network as your LaCie 5big Office/​Office+. **Start > All Programs > Windows Home Server 2011/​Windows Storage Server 2008 R2 > Windows Home Server 2011 Dashboard/​Windows Storage Server 2008 R2 Dashboard**
 +  - Select the **Home** tab.
 +  - Click once on **COMMON TASKS**. \\ {{:​products:​tb-raid:​screenshots:​dashboard_common_tasks.png?​500}}
 +  - Click once on **Disk Management**. \\ {{:​products:​tb-raid:​screenshots:​dashboard_disk_management.png?​500}}
 +  - Note that Disk 1 is Missing and that both the Mirrored and RAID 5 volumes have //Failed Redundancy//​. \\ {{:​products:​tb-raid:​screenshots:​disk_1_fail.png?​600}}
 +  - Remove the failed Disk 1 and insert the replacement. See [[adding-disks]] for instructions on adding new drives into the 5big enclosure.
 +  - The replacement disk is listed as //​Unallocated//​. \\ {{:​products:​tb-raid:​screenshots:​repair_01.png?​600}} ​
 +  - The mirror must be broken before rebuilding it with the replacement disk. Right-click on the **System** volume to select **Remove Mirror…** \\ [{{:​products:​tb-raid:​screenshots:​repair_02a.png?​600|**//​Remove Mirror - System//​**}}]
 +  - In the //Remove Mirror// pop-up window, select **Missing**. Click **Remove Mirror**. \\ {{:​products:​tb-raid:​screenshots:​repair_03.png?​400}}
 +  - Click **Yes** at the Disk Management prompt. \\ {{:​products:​tb-raid:​screenshots:​repair_04.png?​400}}
 +  - Right-click on the **Windows** volume to select **Remove Mirror…**. \\ [{{:​products:​tb-raid:​screenshots:​repair_02b.png?​600|**//​Remove Mirror - Windows//​**}}]
 +  - In the //Remove Mirror// pop-up window, select **Missing**. Click **Remove Mirror**. \\ {{:​products:​tb-raid:​screenshots:​repair_03.png?​400}}
 +  - Click **Yes** at the Disk Management prompt. \\ {{:​products:​tb-raid:​screenshots:​repair_04.png?​400}}
 +  - The mirror has been successfully removed. \\ {{:​products:​tb-raid:​screenshots:​repair_05.png?​600}}
 +  - Right-click on the **System** partition to select **Add Mirror…** \\ {{:​products:​tb-raid:​screenshots:​repair_06.png?​400}}
 +  - From the //Add Mirror// pop-up window, select your replacement disk (in this example, **Disk 1**). Click **Add Mirror**. \\ {{:​products:​tb-raid:​screenshots:​repair_07.png?​400}}
 +  - Click **Yes** at the Disk Management pop-up window. \\ {{:​products:​tb-raid:​screenshots:​repair_08.png?​400}}
 +  - Right-click on the **Windows** partition to select **Add Mirror…** \\ {{:​products:​tb-raid:​screenshots:​repair_09.png?​400}}
 +  - From the //Add Mirror// pop-up window, select your replacement disk (in this example, **Disk 1**). Click **Add Mirror**. \\ {{:​products:​tb-raid:​screenshots:​repair_07.png?​400}}
 +  - Disk Management will begin resynching the Windows Mirror. To save time, you may resync the Data RAID 5 volume while the Windows Mirror is building.
 +  - Right-click on one of the **Data** partitions (do not use the //Missing// disk). Choose **Repair Volume…** \\ {{:​products:​tb-raid:​screenshots:​repair_10.png?​600}}
 +  - In the //Repair RAID-5 Volume// window, choose the disk to repair the Data volume (in our example, **Disk 1**). Click **OK**. The Data volume will start resynching. Please be patient since it will take 15 to 40 hours to resync the RAID 5 volume, depending upon the capacity. \\ {{:​products:​tb-raid:​screenshots:​repair_11.png?​400}}
 +
 +
 +===== Removing the Missing Disk =====
 +
 +Disk Management must be told to remove the //Missing// disk once resynching has begun. Follow the easy steps below to delete the //Missing// disk from the list of drives.
 +
 +  - If you have not closed Disk Management after following the steps to repair the Mirrored and RAID 5 volumes, the //Missing// disk may be listed as a member of the Data volume.
 +  - Go to the the **Action** pulldown menu and choose **Refresh** (**Action > Refresh**) to refresh the list of drives. If the //Missing// disk is still listed as Data, exit and relaunch Disk Management.
 +  - The Missing disk will remain in the list of Disk Management disks. However, it should no longer be a part of the Data volume.
 +  - Right-click on **Missing** to select **Remove Disk**. \\ {{:​products:​tb-raid:​screenshots:​repair_12.png?​600}}
 +  - The //Missing// disk should now be removed from the **Disk Management** list. \\ {{:​products:​tb-raid:​screenshots:​repair_13.png?​400}}
