Hi,

 

I have an active cluster, 3 nodes with 30GB hard disk each and now i'm running out of space. I want to add 100GB hard disk to each one and seperate logs from data etc. What is the right way to do it and how can i do it?

 

Thank you

To add a new disk into a DN/NM config is as easy as configuring their data.dirs/local-dirs keys to the path the disk is mounted as.

To change log dirs, you can use CM configuration fields to set newer locations, or alternatively move the log dirs and create symlinks to the new paths from the original.

Does this help?
