File Metadata Protection
File metadata includes information such as name, owner, permissions, date created, date modified, and a soft link to the file’s storage location.
The FluidFS system has several built‐in measures to store and protect file metadata:
-
Metadata is managed through a separate caching scheme and replicated on two separate volumes.
-
Metadata is check-summed to protect file and directory structure.
-
All metadata updates are journaled to storage to avoid potential corruption or data loss in the event of a power failure.
-
There is a background process that continuously checks and fixes incorrect checksums.
