Creating custom data directories
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
cassandrauser and group:
groupadd -r cassandra
useradd -r -g cassandra cassandra
Create the custom data directory and assign ownership and permissions to the
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.
