If you have two nodes, and RF 2, you will only be able to use eventual
consistency. If you want to have stronger consistency and some redundancy 3
nodes is the minimum requirement.
In the current setup, with only 2 nodes, I would use RAID 10 as it
requires less operator intervention and there is a chance of data loss with
RF 2. If a write (including the hints) is only committed to one node and
the disk on that node fails the write will be lost.
Hope that helps.

Hi,
What about using JBOD and replication factor 2?

Hi all,
I need to setup 2 nodes Cassandra cluster. I know that Datastax
recommends using JBOD as a disk configuration and have replication for the
redundancy. I was planning to use RAID 10 but using JBOD can save 50% disk
space and increase the performance . But I am not sure I should use JBOD
with 2 nodes cluster since there is a higher chance to lose 50% of our
cluster compare to a larger cluster. I may prefer to have stronger nodes if
I have limited number of nodes.
What do you think about that? Is there anyone who has 2 nodes cluster?
Best Regards,
Cem
