The MDS process in my cluster is running at 100% CPU. In fact I thought the cluster came down, but rather an ls was taking a minute. There aren't any clients active. I've left the process running in case there is any probing you'd like to do on it: virt res cpu 4629m 88m 5260 S 92 1.1 113:32.79 ceph-mds Thanks, Noah -- 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
