I switched from a btrfs setup to bcachefs mainly because I like the folder/file based redundancy for it's much better flexibility.

But with my old setup I set up my disk to go to sleep after well with hdparm this setting:

>-S 241

Which should be 30minutes so the harddisk gone to sleep when I did not read from it, now with bcachefs I think it never sleeps so I think the FS does background task all the time even I don't change anything on the setup since many days.

But when I use "fs usage" the "Leaving" column shows some numbers so I think it does something in the back? Or do I misinterpret that?

Maybe I am wrong but I think some background task from bcachefs creates accesses on the harddisk and keeps them from sleeping.
