@msau42 @vishh @jingxu97 I've updated the feature description to fit the new template. Please, fill the empty fields in the new template (their actual state was unclear).

@msau42 @vishh @jingxu97 please, update the feature description, fields "Approver" and "Feature target" are still unclear.

[idvoretskyi]

@jingxu97 @vishh For 1.8 is alpha still correct?

[jingxu97]

I think currently we keep it alpha. We need to finish a number of items lists in #43607

[saad-ali]

@jingxu97 will split this feature issue in to three or more separate feature issues so that it is easier to track.

[jingxu97]

I plan to split this into three features as follows

• Supports storage as one of the node allocatable resources.
• Support local storage isolation at pod and container levels.
• Expose storage usage metrics to end users.

[idvoretskyi]

@jingxu97 @saad-ali have these features been splitted? If yes, please provide us with the links to the new features; and close the current one.

[jingxu97]

I opened up feature #361 #362 #363 to replace this one.
