Hmm, I'm confused by the phrase 'partitions that point to the same disk':

- account, container, object rings can get set to use the same *device* 
(typically an entire disk e.g /dev/sdc). While you could use partitions 
e.g if you are sourcing storage from a SAN...this is not the usual scenario.
- they all 'compete' for the storage, however it is usually the objects 
that eat the most of it (you can put the accounts and containers on 
their own real disks to avoid this...I think the docs suggest this as as 
a good practice).


What happens when you run out of disk is that (eventually) you cannot 
add any more objects or containers. Swift is pretty resilient and can 
cope with *some* devices being full but eventually nothing can be done 
and you need to add more storage nodes and amend ring configuration 
(preferably *before* getting into the situation I described)!
