Symptoms

When you use Storage Spaces on a computer that is running Windows 8 or Windows Server 2012, you experience the following issues:

Issue 1

Assume that you mark a drive as retired, and the spare capacity in the storage pool is insufficient for reallocation. In this situation, the storage space cannot be repaired.

Note When you try to retire a drive and then repair a storage space, the system marks all extents of the storage space that reside on the drive for reallocation.

Issue 2

When Storage Spaces is configured to use enclosure awareness, and a Just a Bunch of Disks (JBOD) failure occurs, the disks are marked as retired incorrectly.

Notes

  • This issue occurs because the enclosure information is not used correctly.

  • This issue causes a rebuild operation to start on the storage spaces that are associated with the retired drives, which significantly increases I/O buffer on the computer. Additionally, user data is at risk because the storage spaces that are associated with the retired drives are in degraded mode. If another drive failure occurs, data will be lost.

Resolution

To resolve this issue, install the Windows RT, Windows 8, and Windows Server 2012 update rollup 2845533, or install the hotfix that is described in this article.
