[Gluster-users] Geo Replication Failure: libgfchangelog.so: cannot open shared object file

[Andy Coates]

We saw this with 4.1.x RPM on OEL (can't recall which specific version and
haven't checked if its fixed in later, at least up to 4.1.6), but the issue
seemed to be it just wasn't symlinked for some reason, so we symlinked
libgfchangelog.so to /lib64/libgfchangelog.so.0

Not sure if the python code is meant to ask for libgfchangelog.so.0 in the
first place, or if the RPM is meant to symlink it post-install.  In 7.x the
script seems to use a different method for finding it too.

Andy.
