Hello, the ceph command hangs after execution (doing what it is supposed to do) following an update on one Jessie machine today. --- # ceph -s cluster d6b84616-ff3e-4b04-b50b-bd398d7fa69a health HEALTH_OK monmap e1: 3 mons at {c-admin=10.0.0.10:6789/0,ceph-01=10.0.0.41:6789/0,ceph-02=10.0.0.42:6789/0}, election epoch 86, quorum 0,1,2 c-admin,ceph-01,ceph-02 osdmap e1676: 4 osds: 4 up, 4 in pgmap v4135542: 1152 pgs, 3 pools, 699 GB data, 182 kobjects 1358 GB used, 98819 GB / 100178 GB avail 1152 active+clean client io 525 kB/s wr, 132 op/s [hangs until ctrl-c] --- I can confirm this problem on SID as well. Since a bunch of python packages were in that update I suspect it is an incompatibility between those and ceph. I will open a debian bug report, but hopefull somebody in the know here will see this message and can act on it. If nothing else, maybe I can stop other people from upgrading before they cripple their cluster.
