Ceph » devops

I am unable to install librados library due to conflict in existing package (ceph-libs) already installed on fedora 18:

1. rpm -ivh librados2-0.61.4-0.fc18.x86_64.rpm
   warning: librados2-0.61.4-0.fc18.x86_64.rpm: Header V4 RSA/SHA1 Signature, key ID 17ed316d: NOKEY
   Preparing... ################################# [100%]
   file /usr/lib64/librados.so.2.0.0 from install of librados2-0.61.4-0.fc18.x86_64 conflicts with file from package ceph-libs-0.46-1.fc18.x86_64

I realize that the contents of librados are already installed as part fo the ceph-libs rpm, but the ceph package has a dependency on librados:

rpm -ivh ceph-0.61.4-0.fc18.x86_64.rpm
warning: ceph-0.61.4-0.fc18.x86_64.rpm: Header V4 RSA/SHA1 Signature, key ID 17ed316d: NOKEY

Hence ceph rpm cannot be installed
