kvm后端存储，使用rbd cp 镜像加上时间标签及uuid方式区别新建的镜像
date+'%Y%m%d-%H-%M'$ rbd cp volumes/CentOS8.3-2011-mode volumes/CentOS8.3-2011-`date+'%Y%m%d-%H-%M'`-`uuidgen`
Image copy: 100% complete...done.
创建好的镜像使用resize方式扩容：
rbd resize volumes/CentOS8.3-2011-2024-11-18-7516fad2-6e99-4576-8862-7e14898766ec --size 1024G $ rbd ls -p volumes
