For now you can expand that space up to actual volume size using
ceph-bluestore-tool commands ( bluefs-bdev-expand and set-label-key).
Which is a bit tricky though.
And I'm currently working on a solution within ceph-bluestore tool to
simplify both expansion and migration.
Thanks,

Sure, but if I remember correctly, Ceph itself cannot use the increased
size: you'll end up with a larger device with unused additional space.
Using that space may be on the TODO, though, so this may not be a
complete waste of space...
