Ronny,
Working with all of the pgs shown in the "ceph health detail", I ran below for each PG to export.
ceph-objectstore-tool --op export --pgid 0.1c --data-path /var/lib/ceph/osd/ceph-0 --journal-path /var/lib/ceph/osd/ceph-0/journal --skip-journal-replay --file 0.1c.export
I have all PGs exported, except 1... PG 1.28. It is on ceph-4. This error doesn't make much sense to me. Looking at the source code from https://github.com/ceph/ceph/blob/master/src/osd/osd_types.cc, that message is telling me struct_v is 1... but not sure how it ended up in the default in the case statement when 1 case is defined... I tried with --skip-journal-replay, fails with same error message.
ceph-objectstore-tool --op export --pgid 1.28 --data-path /var/lib/ceph/osd/ceph-4 --journal-path /var/lib/ceph/osd/ceph-4/journal --file 1.28.export
terminate called after throwing an instance of 'std::domain_error'

Then wrote a simple script to run import process... just created an OSD per PG. Basically ran below for each PG.
mkdir /var/lib/ceph/osd/ceph-5/tmposd_0.1c/
ceph-disk prepare /var/lib/ceph/osd/ceph-5/tmposd_0.1c/
chown -R ceph.ceph /var/lib/ceph/osd/ceph-5/tmposd_0.1c/
ceph-disk activate /var/lib/ceph/osd/ceph-5/tmposd_0.1c/
ceph osd crush reweight osd.$(cat /var/lib/ceph/osd/ceph-5/tmposd_0.1c/whoami) 0
systemctl stop ceph-osd@$(cat /var/lib/ceph/osd/ceph-5/tmposd_0.1c/whoami)
ceph-objectstore-tool --op import --pgid 0.1c --data-path /var/lib/ceph/osd/ceph-$(cat /var/lib/ceph/osd/ceph-5/tmposd_0.1c/whoami) --journal-path /var/lib/ceph/osd/ceph-$(cat /var/lib/ceph/osd/ceph-5/tmposd_0.1c/whoami)/journal --file ./export/0.1c.export
chown -R ceph.ceph /var/lib/ceph/osd/ceph-5/tmposd_0.1c/
systemctl start ceph-osd@$(cat /var/lib/ceph/osd/ceph-5/tmposd_0.1c/whoami)
Sometimes import didn't work.. but stopping OSD and rerunning ceph-objectstore-tool again seems to help or when some PG didn't really want to import .
Unfound messages are gone! But I still have down+peering, or down+remapped+peering.
