[ceph-users] ceph fs reset situation

Hello, list. Have anybody been in the situation when after "ceph fs reset" filesystem becomes blank (mounts OK, ls shows no files/directories), but data and metadata pools still hold something (698G and 400M respectively by "ceph fs status"). Would be grateful for documentation vectors and/or suggestions. Maybe i remember wrong, but few times in the past same "ceph fs reset" produced minor corruption to recent filesystem changes.
