Configuring the disk health checker
Ways to enable, disable, and use the disk health checker>
You can manage the disk health checker in DataStax Enterprise in the following ways:
- Enable and disable the disk health checker.
- Configure the frequency of disk health checking.
- Manage the amount of disk space allowed on a partition for a data directory.
When the disk space exceeds the allowed amount, the node is shut down.
Configure the options in the dse.yaml file, which is located in:- Packaged installations: /etc/dse/dse.yaml
- Tarball installations: install_location/resources/dse/conf/dse.yaml
health_check_interval option
By default, the disk health checker is enabled by DataStax Enterprise 4.0. The health_check_interval option sets the time interval in minutes between each check. Any value greater than 0 enables the disk health checker. By default, the health_check_interval is 5.
To disable the disk health checker, set the health_check_interval option to 0.
min_disk_space_before_failure
By default, the disk health checker allows 10 MB on a partition holding a data directory before shutting down the node.
