ERROR_NOT_READ_FROM_COPY
The selected data copy could not be read
ERROR_NOT_READ_FROM_COPY is associated with redundant storage and means the specifically requested copy was unavailable or unreadable. Another copy may still be usable, but the selected one did not satisfy the read.
Investigation
- Identify which mirror or copy was requested.
- Check member-device health and synchronization state.
- Compare reads from other available copies.
- Schedule repair only after preserving a known-good version.
Handling
Fail over to a verified healthy copy when supported and repair the damaged replica. Do not overwrite all copies using data from an unverified source.
