I was following the instructions in https://www.sebastien-han.fr/blog/2015/09/02/ceph-validate-that-the-rbd-cache-is-active/ because I wanted to look at some of the rbd cache state and possibly flush and invalidate it My ceph.conf has [client] rbd default features = 1 rbd default format = 2 admin socket = /var/run/ceph/$cluster-$type.$id.$pid.$cctid.asok log file = /var/log/ceph/ I have a client only node (no osds) and on that node I ran fio with the librbd engine, which worked fine. But I did not see anything in /var/run/ceph on that client node. Is there something else I have to do? -- Tom Deneau, AMD _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
