2) Main device space is highly fragmented -

1.0 is the maximum. Can't say for sure but I presume it's pretty full
as well.
As I said, these disks aren't that full as far as bytes are concerned.
But they do have a lot of objects on them! As I said we have hundreds of
millions of ~1MB objects in an EC 8+3 pool, which means that there are
billions of 125KB fragments on the OSDs.
About fragmentation: Is there a way to get rid of it?
Does scrubbing/deep scrubbing help?
