Hello, As per another post I been having a huge issue since a PGNUM increase took my cluster offline.. I have got to a point where I have just 20 PG's Down / Unavailable due to not being able to start a OSD I have been able to export the PG from the the offline OSD I then import to a clean / new OSD which is set to weight 0 in Crush using the following command. ceph-objectstore-tool --data-path /var/lib/ceph/osd/ceph-17 --no-mon-config --op import --file /mnt/croit/backup/pg10.0 When I start the OSD I see in the log loads of stuff being transitioned to Stray. Do I need to tell CEPH to used the pg on the OSD to rebuild? When I query the PG at the end it complains about marking the offline OSD as offline? I have looked online and cannot find a definitive guide on how the process / steps that should be taken.
