| Doc Text: |
Previously, some metadata was marked as corrupted because the state tests for the file system snap systems were incorrect. Due to this, the MDS wrongly indicated some metadata is damaged.
With this fix, the state tests for the file system snap systems have been corrected and the MDS no longer indicates the correct metadata as corrupt.
