Ganesha 2.8 in the CentOS Storage SIG is built with Ceph Nautilus (14),
also from the CentOS Storage SIG.
On the surface it's strange that libganesha_nfsd.so is looking for symbols
from librados.
As a short term solution you could try installing the nfs-ganesha-ceph RPM
and see if that helps.

 I'm trying to run nfs-ganesha-2.8.2 on CentOS-7.7 and it's
failing with
 the error shown in the Subject line.  More details below.
 On some other CentOS-7 systems I'm successfully running nfs-ganesha-2.7.6
 from the centos-gluster41 repo, but I thought I'd have a go with the
 nfs-ganesha-2.8.2 from the centos-nfs-ganesha28 repo.  Was that a mistake?
 Is there a good document anyone could point me to that describes current
 recommendations (e.g. what versions to use, what to avoid) for installing
 and using nfs-ganesha on CentOS-7.
 I should point out that I'm only interested in using the PROXY FSAL at
 this time.  This is what I'm happily - for the most part - using with
 nfs-ganesha-2.7.6.
 My google-fu has not turned up an answer, so I'm turning here for help.
 Any help in solving this problem with 2.8.2 or advice about using other
 versions will be much appreciated.  Thanks!
