Breaking a mirrored set

Breaking a mirrored set

You might want to break a mirror for two reasons:

? If one of the mirrored drives in a set fails, disk operations can continue. When users read and write data, these operations use the remaining disk. At some point, however, you need to fix the mirror, and to do this you must first break the mirror, replace the failed drive, and then reestablish the mirror.

? If you no longer want to mirror your drives, you might also want to break a mirror. This allows you to use the disk space for other purposes.

BEST PRACTICES Although breaking a mirror doesn’t delete the data in the set, you should always back up the data before you perform this procedure to ensure that if you have problems, you can recover your data.

In Disk Management, you can break a mirrored set by following these steps:

1. Press and hold or right-click one of the volumes in the mirrored set, and then tap or click Break Mirrored Volume.

2. Confirm that you want to break the mirror by tapping or clicking Yes. If the volume is in use, you’ll get another warning dialog box. Confirm that it’s okay to continue by tapping or clicking Yes.

Windows Server 2012 R2 breaks the mirror, creating two independent volumes.
