[ceph-users] Re: Questions about rbd flatten command

I'm not sure, but it seems that read and write operations are performed for all objects in rbd. If so, is there any method to apply qos for flatten operation? 2024년 4월 1일 (월) 오후 11:59, Henry lol <pub.virtualization@gmail.com>님이 작성:

Hello,

I executed multiple 'rbd flatten' commands simultaneously on a client. The elapsed time of each flatten job increased as the number of jobs increased, and network I/O was nearly full.

so, I have two questions. 1. isn’t the flatten job running within the ceph cluster? Why is client-side network I/O so high? 2. How can I apply qos for each flatten job to reduce network I/O?

Sincerely,
