> h5. {*}Container Level Info (Tab1){*}: A new tab as shown below will present
> the container level info showing mismatch between SCM and OM. Some containers
> are deleted in SCM but seem to be referred to by files/keys in OM, So recon
> needs to detect if any container is missing or not from OM perspective. This
> requirement came up due to missing containers in the BoFA “Preferred
> Networks” cluster where OM still maintains those deleted containers along
> with key mapping and those keys cannot be reached as containers doesn’t
> exists at SCM, which is a data loss situation.Issue details are at
> https://issues.apache.org/jira/browse/HDDS-7701.
> Here in this tab, below list of containers will be shown along with their key
> mappings:
>
> * Container is present in OM, but not in SCM.
> * Container is present in SCM, but not in OM.
> If a container is present in both OM and SCM, then it is of no relevance and
> will not be shown here.
> UI representation can be a tabular format with “Container Id”,
> “ContainerState”, “Keys”, “Exists At”
>
>
>
> h5. Key Level Info (Tab 2): A new tab as shown above will be used to
> represent below information.
> * Number of open keys.
> * Amount of data mapped to open keys.
> * Number of pending delete keys.
> * Amount of data mapped to pending delete keys
> * Keys that are mapped to containers in *DELETED* state in *SCM*
> * Should never happen, but we want to show this in case if any.
> * Orphan keys/file paths and the amount of data mapped to such orphan
> keys/paths.
> * Orphan key/file path.
> * Amount of data mapped to such keys/files.
> * Container Id holding such keys in OM.
