[NFS-Ganesha-Support] CentOS 7 Dependency Issues surrounding userspace-rcu

Wednesday, 7 August 2019

Hello all, I am encountering dependency issues in installing nfs-ganesha,
and I’m hoping someone here may be able to help.

I have a dedicated CentOS 7 VM for the purpose of running nfs-ganesha with
the CephFS FSAL, pointed towards my existing Ceph cluster. I have installed
the centos-nfs-ganesha28 release RPM, and have that repository enabled. I
also have the Ceph Nautilus release RPM for el7 installed, which provides
repositories of that release.

I have these repositories enabled:

When I try to yum install nfs-ganesha, I get this dependency error:

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

If I remove the EPEL repository, then I instead reach the following issue:
librados2 cannot install correctly.
