Hi, cephers We are testing the RDMA ms type of Ceph. The OSDs and MONs are always marked down by their peers because they don't have enough buffer to use in the memory buffer pool to reply the heartbeat ping message from their peers. The log always shows "no enough buffer in worker" even though the whole cluster is idle without any I/Os from external. -- 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
