Hi Sam, > Sounds like you needed osd 20. You can mark osd 20 lost. > -Sam Does not work: # ceph osd lost 20 --yes-i-really-mean-it osd.20 is not down or doesn't exist Also, here is an interesting post which I will follow from October: http://lists.ceph.com/pipermail/ceph-users-ceph.com/2014-October/044059.html " Hello, all. I got some advice from the IRC channel (thanks bloodice!) that I temporarily reduce the min_size of my cluster (size = 2) from 2 down to 1. That immediately caused all of my incomplete PGs to start recovering and everything seemed to come back OK. I was serving out and RBD from here and xfs_repair reported no problems. So... happy ending? What started this all was that I was altering my CRUSH map causing significant rebalancing on my cluster which had size = 2. During this process I lost an OSD (osd.10) and eventually ended up with incomplete PGs. Knowing that I only lost 1 osd I was pretty sure that I hadn't lost any data I just couldn't get the PGs to recover without changing the min_size. " It is good that this worked for him, but it also seems like a bug that it worked! (I.e. ceph should have been able to recover on its own without weird workarounds.) I'll let you know if this works for me! Thanks, Chad. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
