Claims (68)

1. A method comprising:

monitoring, by a storage management system configured to provide a first storage volume and a second storage volume to a file system separate from the storage management system, one or more first attributes associated with the first storage volume;

monitoring, by the storage management system, one or more second attributes associated with the second storage volume;

setting, by the storage management system and based on the monitoring of the one or more first attributes, a first discard option to be enabled for the first storage volume;

setting, by the storage management system and based on the monitoring of the one or more second attributes a second discard option to be disabled for the second storage volume;

detecting, by the storage management system, a first request to delete data stored on one or more first blocks within a first storage device associated with the first storage volume;

detecting, by the storage management system, a first discard request automatically issued, based on the first discard option being enabled, by the file system in response to the first request to delete data, the first discard request commanding the first storage device to free the one or more first blocks for use by the file system to store additional data;

detecting, by the storage management system, a second request to delete data stored on one or more second blocks with a second storage device associated with the second storage volume; and

initiating, by the storage management system in response to the second request to delete data and based on both the second discard option being disabled and a load metric associated with the second storage volume, a second discard request to the second storage device.

2. The method of claim 1 , wherein the one or more second attributes comprises one or more attributes associated with an application utilizing the second storage volume.

3. The method of claim 2 , wherein the one or more attributes associated with the application comprises a type of the application.

4. The method of claim 3 , wherein:

the one or more attributes associated with the application comprises a typical ratio of delete requests to write requests issued by the type of application; and

the setting the second discard option to be disabled is based on the typical ratio of delete requests to write requests meeting a threshold ratio.

5. The method of claim 3 , wherein:

the monitoring the one or more second attributes comprises monitoring an actual ratio delete requests to write requests issued by the application; and

the setting the second discard option to be disabled is based on the actual ratio of delete requests to write requests meeting a threshold ratio.

6. The method of claim 5 , further comprising adjusting an initial setting of the second discard option for the type of application based on the actual ratio of delete requests to write requests issued by the application.

7. The method of claim 1 , wherein:

the one or more second attributes associated with the second storage volume comprises a metric indicating a ratio of delete requests to write requests received by the second storage volume; and

the setting the second discard option to be disabled is based on the metric meeting a threshold metric.

8. The method of claim 1 , wherein:

the one or more second attributes associated with the second storage volume comprises a type of the second storage device associated with the second storage volume; and

the setting the second discard option to be disabled is based on the type of the second storage device being a solid-state based storage device.

9. The method of claim 1 , wherein the monitoring the one or more first attributes and the monitoring the one or more second attributes are performed by a container storage management system.

10. A system comprising:

one or more memories storing computer-executable instructions; and

one or more processors to execute the computer-executable instructions to:

provide a first storage volume and a second storage volume to a file system;

monitor one or more first attributes associated with the first storage volume;

monitor one or more second attributes associated with the first second volume;

set, based on the monitoring of the one or more first attributes, a first discard option to be enabled for the first storage volume;

set, based on the monitoring of the one or more second attributes a second discard option to be disabled for the second storage volume;

detect a first request to delete data stored on one or more first blocks within a first storage device associated with the first storage volume;

detect a first discard request automatically issued, based on the first discard option being enabled, by the file system in response to the first request to delete data, the first discard request commanding the first storage device to free the one or more first blocks for use by the file system to store additional data;

detect a second request to delete data stored on one or more second blocks with a second storage device associated with the second storage volume; and

initiate, in response to the second request to delete data and based on both the second discard option being disabled and a load metric associated with the second storage volume, a second discard request to the second storage device.

11. The system of claim 10 , wherein the one or more second attributes comprises one or more attributes associated with an application utilizing the second storage volume.

12. The system of claim 11 , wherein the one or more attributes associated with the application comprises a type of the application.

13. The system of claim 12 , wherein:

the one or more attributes associated with the application comprises a typical ratio of delete requests to write requests issued by the type of application; and

the setting the second discard option to be disabled is based on the typical ratio of delete requests to write requests meeting a threshold ratio.

14. The system of claim 12 , wherein:

the monitoring the one or more second attributes comprises monitoring an actual ratio of delete requests to write requests issued by the application; and

the setting the second discard option to be disabled is based on the actual ratio of delete requests to write requests meeting a threshold ratio.

15. The system of claim 14 , further comprising adjusting an initial setting of the second discard option for the type of application based on the actual ratio of delete requests to write requests issued by the application.

16. The system of claim 10 , wherein:

the one or more second attributes associated with the second storage volume comprises a metric indicating a ratio of delete requests to write requests received by the second storage volume; and

the setting the second discard option to be disabled is based on the metric meeting a threshold metric.

17. The system of claim 10 , wherein:

the one or more second attributes associated with the second storage volume comprises a type of the second storage device associated with the second storage volume; and

the setting the second discard option to be disabled is based on the type of the second storage device being a solid-state based storage device.
