Ceph

This is most probably a timeout because individual udev actions take too long and abort or fail (I don't know exactly what happens when a udev action takes long to complete). This cannot happen in infernalis but the modifications are extensive and not easy to backport. The general idea is to not do any work when ceph-disk is called from udev. Instead ceph-disk trigger is called and launches a systemd/upstart action in the background.

Ok thanks for the update. We are evaluating Infernalis for our next deployment, and I have a script that cleans up from the broken state on boot, so we can limp along as is if this needs to be WONTFIX.
