Hi all, We found that cache-tier forward mode is hanging in luminous 12.2.1. It seems that the client is keep sending request to cache-tier's osd and the osd always replied redirect to client. This seems due to this patch: https://github.com/ceph/ceph/commit/9adb68f5e206c167b97ec89935cbdaeb462173d8#diff-847b3447bebb2f031678eef0a2aea60d I added “CEPH_OSD_FLAG_IGNORE_OVERLAY” to the op to force it skips cache-tier when client got redirect reply and it seems to work. Is there any potential issue of adding this flag here? in src/osdc/Objecter.cc void Objecter::handle_osd_op_reply(MOSDOpReply *m) { … … if (m->is_redirect_reply()) { … op->target.flags |= (CEPH_OSD_FLAG_REDIRECTED | CEPH_OSD_FLAG_IGNORE_OVERLAY); ... } } Thanks, TY Lin-- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
