Summary

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

Causes

The majority of the pool drives hosting space metadata for a storage space can fail a metadata update for the following reasons:

  • Physical drives might fail requests with device IO errors
  • Insufficient number of physical drives have online storage space metadata
  • Insufficient memory resources

Resolutions

To resolve the problem:

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