heres output of 'ceph -s' from a kvm instance running as a ceph node. all 3 nodes are monitors, each with 6 4gig osds. mon_osd_full ratio: .611 mon_osd_nearfull ratio: .60 whats 23689MB used? is that a buffer because of mon_osd_full ratio? is there a way to query a pool for how much usable space is really available to clients? for example, in this case, 3 nodes, 6osds, 4G each = 72G, so with a replica size of 3, id like to see something that says close 20G available, 1.7G in use. ceph3:~# ceph -s cluster 2198abdb-2669-438a-8673-fc4f226a226c health HEALTH_OK monmap e1: 3 mons at {ceph1=172.21.0.31:6789/0,ceph2=172.21.0.32:6789/0,ceph3=172.21.0.33:6789/0}, election epoch 16, quorum 0,1,2 ceph1,ceph2,ceph3 osdmap e104: 18 osds: 18 up, 18 in pgmap v5557: 600 pgs, 1 pools, 1694 MB data, 432 objects 23689 MB used, 49858 MB / 73548 MB avail 600 active+clean _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
