How do I know what's stored in the remote storage?

Hello, I'm kind of confused about the amount of disk space JuiceFS is using on the remote storage (scw). The following commands were run in the mounted directory.

$ du -sh
51G	.
$ du -sh .trash/
31G	.trash/

I would expect the remote storage to take ~51G. The remote storage's administration however says it takes over 132G (~122 GiB) and I know that this number is correct. I tried running both gc and fsck but the occupied space has not been freed.

$ juicefs gc --delete "sqlite3://<...>.db"

In fact, it seems the amount of data is constantly growing despite me not writing any data to the mounted directory (only random reads). How can I inspect what's happening? Thanks.

Does Scaleway Object Storage have minimum billing unit? For example, if the minimum billing unit is 64KiB, then those files that size less than 64KiB will be account as 64KiB.

It doesn't.
