Subject cassandra nodes with mixed hard disk sizes
Date Mon, 21 Mar 2011 20:50:25 GMT

This is a two part question ...

1. If you have cassandra nodes with different sized hard disks,  how do you deal with assigning
the token ring such that the nodes with larger disks get more data?   In other words, given
equally distributed token ranges, when the smaller disk nodes run out of space, the larger
disk nodes with still have unused capacity.    Or is installing a mixed hardware cluster a

2. What happens when a cassandra node runs out of disk space for its data files?  Does it
continue serving the data while not accepting new data?  Or does the node break and require
manual intervention?

This info has alluded me elsewhere.
