## work notes

* balanced= and fullybalanced= need to limit the set of repositories to
|
||||
ones with enough free space to contain a key.
|
||||
* `fullybalanced=foo:2` can get stuck in suboptimal situations. Eg,
|
||||
when 2 out of 3 repositories are full, and the 3rd is mostly empty,
|
||||
it is no longer possible to add new files to 2 repositories.
|
||||
Moving some files from one of the full repositories to the empty one
|
||||
would improve things, but is there any way for fullybalanced to know
|
||||
when it makes sense to do that?
|
||||
|
||||
* document balancing algo well enough that someone else could implement it
|
||||
from the design doc
|
||||
If this is not resolved, it may be better to lose the ":number" part
|
||||
of balanced and fullybalanced. With 1 copy balanced, this situation does
|
||||
not occur. Users wanting 2 copies can have 2 groups which are each
|
||||
balanced, although that would mean more repositories on more drives.
|
||||
|
||||
* picking a low UUID and picking keys that mod N == 0 would let an attacker
|
||||
generate keys that balancing always puts on that UUID. To avoid this

prevented by adding another UUID to the set, it could even be a dummy

UUID that is marked as having 0 size, so it will never be used.
