Not all historical nodes download segments from deep storage

Hi experts,

I found after I deleted the cached segments of some dataSource and restart Druid cluster, not all historical nodes in the cluster would download segments from deep storage. How to make all historical nodes download segments?

One more question, will each historical node cache all segments of one dataSource?

Thank you.

Can someone give me a hint?

What do you mean you deleted cached segments? Manually from a historical?
