Repository size does not change after running BFG and pushing to remote

[dmytrob]

Hi,
I have a repository where some binary files were committed accidentally and many times. Thus, repository size is ~2.4GB if I do a fresh clone.
Then I run BFG

java -jar bfg-1.14.0.jar --strip-blobs-bigger-than 3M .

output

Deleted files

	...

after that size of local checkout is

$ du -sch . 
2,4G	.
2,4G	total

then I run

git reflog expire --expire=now --all && git gc --prune=now --aggressive

Output

$ du -sch . 
150M	.
150M	total

Finally I push it to remote

git push --force 

Afterwards I clone the repo again, in an another directory, and the directory has size of 2.4GB again.

Apparently I do something wrong, or in a wrong order, but can't figure out what exactly.

Could someone please clarify what is the proper workflow here?

Thanks!

Are you doing a mirror clone like the guide specifies?
git clone --mirror git://example.com/some-big-repo.git

hi,
yes, I tried both wit --mirror and without and the result is the same
