Hi Sage, I try to make the following. ceph-objectstore-tool --data-path /var/lib/ceph/osd/ceph-49/ --journal /var/lib/ceph/osd/ceph-49/journal --pgid 11.182 --op export-remove --debug --file /tmp/export-pg/18.182 2>ceph-objectstore-tool-export-remove.txt but this rise exception find here https://filesender.belnet.be/?s=download&token=e2b1fdbc-0739-423f-9d97-0bd258843a33 file ceph-objectstore-tool-export-remove.txt Kr Philippe. ________________________________________ From: Sage Weil <sage@xxxxxxxxxxxx> Sent: 04 February 2019 06:59 To: Philippe Van Hecke Cc: ceph-users@xxxxxxxxxxxxxx; Belnet Services Subject: Re: Luminous cluster in very bad state need some assistance.

If PGs are damaged, removing the pool would be part of getting to HEALTH_OK, but you'd probably also need to remove any problematic PGs that are preventing the OSD starting. But keep in mind that (1) i see 3 PGs that don't peer spread across pools 11 and 12; not sure which one you are considering deleting. Also (2) if one pool isn't fully available it generall won't be a problem for other pools, as long as the osds start. And doing ceph-objectstore-tool export-remove is a pretty safe way to move any problem PGs out of the way to get your OSDs starting--just make sure you hold onto that backup/export because you may need it later! > PS: don't know and don't want to open debat about top/bottom posting but would like to know the preference of this list :-) No preference :) sage _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
