Hi All,
Would anybody have an idea a) If it's possible and b) if it's a good idea
to have more EC chunks than the total number of hosts?
For instance if I wanted to have a k=6 m=2, but only across 4 hosts and I
wanted to be able to withstand 1 host failure and 1 disk failure(any host),

Hi All,
Does anybody have any input on what the best ratio + total numbers of Data +
