Dear All,
I'm using metadata repair tools to repair a damaged MDS following below document. My
storage has about 276TB data. Cephfs-data-scan is using 32 workers. How long will it take
to finish scanning extents? What about scanning inodes? It has run 6 hours and metadata
pool dropped 1G. Is this normal? Thanks.
