Hi Team, I have a cluster with 1 broker, 2 coordinators / overlords, 3 middlemanagers and 12 historicals.
My console from the coordinator

Problems:

1.- Kafka Indexing Service tasks no displayed.

2.- I have 4.4 TB in deep storage, only show 676 GB, all 4.4 TB can be query.

3.- All 12 historical have 87 % of disk usage, this means 15,66 TB loaded of segments, my replication is 2, this will be 8.8 TB.

I think the problems start after use the insert-segment-to-db Tool.

Thanks.
