Windows Host Unresponsive

Windows hosts running Windows Server 2008 R2 may:
  • Become unresponsive
  • Log a \Device\Harddisk\ error event
  • Display a write-protected error (see below)


This condition is caused by implementing a performance policy with the Set to Non-Writable option on a thin-provisioned volume. This option converts the volume to read-only when the quota is reached or the volume space is full, rather than taking the volume offline.

Use the Set Offline option for hosts running Windows Server 2008 R2.
