Though the CACHE_SET has succeeded, as I can read that value from memcached:
# nc 10.250.1.11 11211
get eee2cd7c98a7757eb08b8c1c9be32dcf15e4b4fc
VALUE eee2cd7c98a7757eb08b8c1c9be32dcf15e4b4fc 1 177
cdogpile.cache.api
CachedValue
...
.
END
If I interpret the dogpile.cache docs properly, the set function will never have a return value, so checking for that in nova/consoleauth/manager.py L94+L106 seems outdated.
Hmm, even after setting everything up properly, I am seeing warnings like this:
