I got to this situation several times, due to a strange behavior in the
xfs filesystem - I initially ran on debian, afterwards reinstalled the
nodes to centos7, kernel 3.10.0-229.14.1.el7.x86_64, package
xfsprogs-3.2.1-6.el7.x86_64. Around 75-80% of usage shown with df, the
disk is already full.
To delete PGs in order to restart the OSD, I first lowered the weight of
the affected OSD, and observed which PGs started backfilling elsewhere.
Then I deleted some of these backfilling PGs before trying to restart
the OSD. It worked without data loss.

According to
http://docs.ceph.com/docs/master/rados/troubleshooting/troubleshooting-osd/
"If you cannot start an OSD because it is full, you may delete some
data by deleting some placement group directories in the full OSD."
