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

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

To resolve the problem:

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