[Gluster-users] Suggested method for replacing an entire node

[Alastair Neil]

I think you should back up /var/lib/glusterd and then restore it after the
reinstall and installation of glusterfs packages.  Assuming the node will
have the same hostname and ip addresses and you are installing the same
version gluster bits, I think it should be fine.  I am assuming you are not
using ssl for the connections if so you will need to back up the keys for
that too.
