This topic describes how to troubleshoot failures occurred when reading storage space configuration from physical drives.


You can experience all physical drives failing to read their configuration or returning corrupt data for storage spaces for the following reasons:

  • Physical drives might fail requests with device IO errors
  • Physical drives might contain corrupted storage pool configuration data
  • Insufficient memory resources


To resolve the problem:

  • If there are missing drives, reconnect the missing drives.
  • Verify physical drives are functional. Replace failed physical drives if necessary.
