Hi Wido, Just to make sure I have everything straight, > If the PG still doesn't recover do the same on osd.307 as I think that 'ceph pg X query' still hangs? > The info from ceph-objectstore-tool might shed some more light on this PG. You mean run the objectstore command on 307, not remove that from the CRUSH map too. Am I correct? Assuming I am, I tried this command on all OSDs in that PG, including 307 and they all say "PG '1.323' not found", which is weird and worrying. Best regards, George
