Hi,
Do your disks have the same size? AFAK Cassandra distributes data with
proportion to disk size, i.e. keeps the same percent of busy space.

Dear All,
We are using multiple disks per node and find the data is not evenly
distributed (data01 uses 1.1T, but data02 uses 353G). Is this expected? If
data01 becomes full, would the node be still writable? We are using 2.2.6.
Thanks,
Xihui
