Maybe someone else can answer. ------------------ Original ------------------ From: "Loris Cuoghi";<l...@stella-telecom.fr>; Date: Tue, Dec 22, 2015 07:31 PM To: "ceph-users"<ceph-users@lists.ceph.com>; Subject: Re: [ceph-users] ceph journal failed??

If you don't have a journal anymore, the OSD has already quit, as it can't continue writing, nor it can assure data consistency, since writes have probably been interrupted. The Ceph's community general assumption for a dead journal, is a dead OSD. But. http://www.sebastien-han.fr/blog/2014/11/27/ceph-recover-osds-after-ssd-journal-failure/ How does this apply in reality? Is the solution that S??bastien is proposing viable? In most/all cases? Will the OSD continue chugging along after this kind of surgery? Is it necessary/suggested to deep scrub ASAP the OSD's placement groups? _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com <br></ceph-users@lists.ceph.com></l...@stella-telecom.fr> _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
