Clear HCD data directories

To delete all database data from a Hyper-Converged Database (HCD) installation, you must clear the /data, /commitlog, /saved_caches, and /hints directories. This can be accomplished with sudo rm -rf on the relevant directories.

sudo rm -rf is a forceful, recursive delete operation on one or more directories. It removes all contents of the specified directories, including nested subdirectories, without seeking intervention from the user. This includes SSTables, commit logs, and other files that are typically used for data recovery. If you need to preserve any data, ensure that it is stored in a separate location from your HCD installation.

Stop the node.
Delete the contents of the HCD data directories.
The following examples use the default directories. If you use non-default directories, target those directories instead of the default directories. To clear only one directory or a subdirectory, target that specific directory path only.

By default, the data directories for tarball installations are subdirectories of the HCD installation directory. This example changes to the installation directory and then targets the relevant subdirectories.

+
cd INSTALL_DIRECTORY && sudo rm -rf data/* commitlog/* saved_caches/* hints/*
To clear data on multiple nodes, repeat these steps on each node.
