Hi Geoff,
Great article. Just wanted let you know that I tested the configuration on my
test environment and everything worked as you described, apart from the
'Recovering from Host Failures' bit.
In my case the former master came up after reboot and joined the pool as a
slave. No manual steps were needed. Below is the extract from the messages on
the host.

Caught an exception flushing database (perhaps it hasn't been initialised yet):
INTERNAL_ERROR: [ Failure("hd") ]; restarting immediately
It could be because I have applied patches up to XS62E014 and something was
fixed.
Best regards
Yuri
