This topic describes how to troubleshoot failures that occurred when reading storage space configuration from physical drives in a Storage Spaces storage pool.


A physical drive can fail to read the configuration or return corrupt data for the following reasons:

  • The physical drive might fail requests with device IO errors
  • The physical drive might contain corrupted storage space configuration data
  • Insufficient memory resources


To resolve the problem verify that the physical drive is functional. Replace failed physical drives if necessary.
