USING CHECKSUMS TO PROTECT YOUR DATA
To safeguard customer data, Qumulo Core has features such as protection against media failure and validation of data integrity on aging media by means of a disk scrubber. The following list gives some common examples of common causes of issues with aging media that Qumulo Core protects against.
|Bit error or bit rot
|Lost data on power-off
|Firmware power state issue
|Write bad data or location
|Firmware writing bug
|Read bad data
|Firmware caching bug
To complement our existing protection against media errors, firmware issues, and bit errors, the Advanced Data Integrity (ADI) feature ensures that your file system and metadata have checksums on all data stored in your Qumulo cluster.
Verifying ADI Availability on Your Cluster
To verify that ADI is enabled on your cluster, use the
qq checksumming_get_status CLI command.
