Subject Adding disk to operating C*
Date Wed, 07 Mar 2018 06:26:18 GMT

I use 5 nodes to create a cluster of Cassandra. (SSD 1TB)

I'm trying to mount an additional disk(SSD 1TB) on each node because each disk usage growth
rate is higher than I expected. Then I will add the the directory to data_file_directories
in cassanra.yaml

Can I get advice from who have experienced this situation?
If we go through the above steps one by one, will we be able to complete the upgrade without
losing data?
The replication strategy is SimpleStrategy, RF 2.

Thank you in advance
