Storagenode ver 1.101.3.
The trash walker it’s called: pieces:trash. You missed the final “s”.
The used-space-filewalker, I believe, now it’s called piecestore:cache. I found an entry about it beeing bypassed by the run command; I use:
--pieces.enable-lazy-filewalker=false \
--storage2.piece-scan-on-startup=false
Does it reffers to something else?
