> Recon Server at a high level will maintain a global view of Ozone that is not available from SCM or OM. Things like how many volumes exist; and how many buckets exist per volume; which volume has maximum buckets; which are buckets that have not been accessed for a year, which are the corrupt blocks, which are blocks on data nodes which are not used; and answer similar queries.
