Quick Reference Table
| # | Scenario | Key Error Signal | Root Cause | The Fix |
|---|---|---|---|---|
| 5 | volume — Forced detachment left filesystem in inconsistent state | Forced detachment of a stuck volume can cause damage to the file system or the data it contains or an inability to attach a new volume using the same device name, unless you reboot the instance. | Unsafe forced detachment left the instance's block device mapping or filesystem in an inconsistent state. | Reboot the instance. |
| 6 | checksum — GetSnapshotBlock checksum mismatch | If the checksum that you generate doesn't match what Amazon EBS provided, you should consider the data not valid and retry your request. | The Base64-encoded SHA256 checksum returned by the GetSnapshotBlock API does not match the client-computed checksum, indicating data corruption in transit. | N/A |
| 7 | checksum — PutSnapshotBlock checksum validation failure | The checksum that you provide is validated against a checksum generated by Amazon EBS to validate the integrity of the data. If the checksums do not correspond, the request fails. | The Base64-encoded SHA256 checksum provided in the PutSnapshotBlock request does not match the payload received by EBS. | N/A |
