Out of curiosity, why are you taking a scale-up approach to building your
ceph clusters instead of a scale-out approach? Ceph has traditionally been
geared towards a scale-out, simple shared nothing mindset. These dual ToR
deploys remind me of something from EMC, not ceph. Really curious as I'd

I followed the install doc however after deploying the monitor, the doc
states to start the mon using Upstart. I learned through digging around
that the Upstart package is not installed using Make Install so it won't
work. I tried running "ceph-mon -i [host]" and it gives an error. Any ideas?

FWIW, I use a CLOS fabric with layer 3 right down to the hosts and multiple
ToRs to enable HA/ECMP to each node. I'm using Cumulus Linux's "redistribute
neighbor" feature, which advertises a /32 for any ARP'ed neighbor. I set up the
hosts with an IP on each physical interface and on an aliased l
Just in case anyone was curious as to how amazing ceph actually is, I did
the migration to ceph seamlessly. I was able to bring the other two nodes
into the cluster, and then turn on replication between them without a
hitch. And with zero downtime. Just incredible software.
