Description

when create snap from an image of huge size, like 64T, it takes for almost 60s in our server enviroment, even if the image exsits without actual data. more harmfully, it stalls the osd holding image header object for 100% cpu usage, impacting client IO drops very much, possibly down to zero.
when rm snap, it also take 60s, which is a long time.
