Hey,
Yes, you can use either of these commands depending on whether or not you are
using containers to get live OSDs's bluestore fragmentation:
ceph daemon osd.0 bluestore allocator score block
or
cephadm shell ceph daemon osd.0 bluestore allocator score block
...
{
"fragmentation_rating": 0.060519485819245739
}
Regards,
Frédéric.
