An example method for monitoring volume dependencies for security threats comprises: detecting a request to perform an operation with respect to a volume included in a plurality of volumes included in a storage system; determining, based on a dependency mapping that specifies dependencies between the plurality of volumes, that performance of the operation would affect a dependency between the volume and one or more other volumes included in the plurality of volumes; and determining, based on the determining that the performance of the operation would affect the dependency between the volume and the one or more other volumes, that the request is possibly associated with a security threat against data stored by the storage system.

Volume dependencies in a storage system

An example method for optimizing data deletion in a storage system comprises: monitoring one or more attributes associated with a storage volume associated with a file system; and setting, based on the monitoring of the one or more attributes, a discard option to be either enabled or disabled for the storage volume, wherein when the discard option is enabled, the file system is configured to automatically issue a discard request in response to a request to delete data stored on one or more blocks within a storage device associated with the storage volume, the discard request configured to command the storage device to free the one or more blocks for use by the file system to store additional data; and when the discard option is disabled, the file system does not automatically issue the discard request in response to the request to delete the data.

Optimizing data deletion settings in a storage system

An example method for optimizing data deletion in a storage system comprises: detecting a command to delete data from a storage volume using a file system, the data stored on one or more blocks within a storage device associated with the storage volume; monitoring a load metric associated with the storage volume, the load metric indicative of a dynamically changing operational load of the storage volume; and initiating, based on the detecting the command and on the monitored load metric, a discard request for the storage device, the discard request commanding the storage device to indicate that the one or more blocks are free for use by the file system to store additional data.
