Trash folder wasting useable space

Garbage Collection
Every 5 days the satellite will send a bloomfilter to the storage node. The storage node will use it to identify garbage pieces. In the storage node log you will notice a few delete messages but on disk the space will still be used for additional 7 days. The logging is currently missleading. First we move the pieces into a trash folder and 7 days later we delete it without any additional log messages. If something goes wrong and the satellite sends empty bloomfilters we can send a command to all storage nodes and they will automatically recover the content of the trash folder. It is better to have a disaster recovery plan even if it is unlikely to happen.

If your trash folder is filled by pieces, this is only mean that your node was offline when customer deleted data.
So, if you want to do not have a trash - please. keep your node online
