We are using FDB 6.2 version . We deleted all data using clearrange \x00 \xff command. Status shows as follows and disk space utilization is still high/same (155 GB used out of 184GB on each node).
Is this expected as i was expecting disk space utilization to go down after clearing data in 6.2 version. If disk space not going down but available for the application to write then I am ok with it but just checking in case we really need to reclaim the space any way to do that.
Status showing 9 TB disk space utilization which is close to 184 GB per node * 55 nodes = 10 TB.
