Hello, I ran "apt upgrade" on Ubuntu 16.04 on one node, now the two OSDs on the node are not starting any more. >From the apt log it looks like many Ceph packages were upgraded from 12.2.1-1xenial to 12.2.2-1xenial. In both OSD logs I can see the following: 2018-02-18 22:24:14.424425 7f5f96a18e00 0 set uid:gid to 64045:64045 (ceph:ceph) 2018-02-18 22:24:14.424443 7f5f96a18e00 0 ceph version 12.2.2 (cf0baeeeeba3b47f9427c6c97e2144b094b7e5ba) luminous (stable), process (unknown), pid 6272 2018-02-18 22:24:14.427532 7f5f96a18e00 -1 Public network was set, but cluster network was not set 2018-02-18 22:24:14.427538 7f5f96a18e00 -1 Using public network also for cluster network 2018-02-18 22:24:14.430271 7f5f96a18e00 0 pidfile_write: ignore empty --pid-file 2018-02-18 22:24:14.431859 7f5f96a18e00 -1 load dlopen(/usr/lib/ceph/erasure-code/libec_jerasure.so): /usr/lib/ceph/erasure-code/libec_jerasure.so: undefined symbol: _ZN4ceph6buffer3ptrC1ERKS1_ Any advice how to get the node running again?
