Something wrong with trash?

no old files in trash folders, but trash size in node GUI shows still same constant 0.9 TB

This is only mean that you DBs are not updated. You need to figure out - why.
Do you have database locks or a malformed/destroyed databases? (database is locked, file is not a database, database is malformed, i/o error, etc.)?
Do you have FATAL errors? Or maybe restarts in the middle of filewalkers?
Do you have all filewalkers successfully finished for all satellites?

Filewalker status

Logs should be at least info level Used space filewalker docker logs storagenode -f 2>&1 | grep "used-space-filewalker" | grep -E "started|finished" GC filewalker docker logs storagenode -f 2>&1 | grep "gc-filewalker" | grep -E "started|finished" retain docker logs storagenode -f 2>&1 | grep "retain" collector docker logs storagenode -f 2>&1 | grep "collector" trash docker logs storagenode -f 2>&1 | grep "piece:trash"
