Creating custom data directories

About this task

To ensure that Lifecycle Manager (LCM) does not delete or overwrite data, it will not automatically create data directories in non-default locations, or manage their permissions. Complete the following steps to use a custom data directory.

The following commands use the useradd and groupadd commands. These examples are not comprehensive for all environments, but instead provide an illustrative example. Use whichever common utility is employed by your organization to complete these steps.

Procedure

Create the cassandra user and group:

groupadd -r cassandra

useradd -r -g cassandra cassandra

Create the custom data directory and assign ownership and permissions to the cassandra user:

mkdir /opt/my-custom-dir

chown cassandra:cassandra /opt/my-custom-dir

chmod 750 /opt/my-custom-dir

If additional custom directories are required, repeat the previous step to create the directories and assign proper ownership and permission.
