We found the solution for our High read volume bytes with help of DSE, we made
following change
$ lvchange -r 16 <lv_name>
Following parameter in cassandra.yaml:-
disk_access_mode: mmap_index_only
Thank you.

Might be a silly question, but did you run "nodetool upgradesstables" and
convert to the 3.0 format? Also, which 3.0? Newest, or an earlier 3.0.x?

Hello,
We recently upgrade C* from 2.1 to 3.0. After the upgrade we are seeing
increase in the total read bytes and read ops on the EBS volumes. It almost
doubled on all the nodes. The number of writes are same.
Thank you.
