Thanks llya.The following is the solution.
3.8 is missing a *ton* of fixes, I'd strongy recommend an upgrade to
4.0+.
If the osdc output is still the same, try marking osd28 down with "ceph
down 28" (it'll come back automatically) and triggering some I/O (e.g.
a small read from a file you can open). You should see
libceph: osd28 down
libceph: osd28 up
in the dmesg after the I/O is triggered.
Attach
# ceph -s
# find /sys/kernel/debug/ceph -type f -print -exec cat {} \;
when you are done.
