remove all objects from a pool

Ceph 스토리지의 특정 Pool 안의 모든 데이터를 다 날리고 싶을때는 아래 명령어를 사용한다.

rados purge <pool-name> --yes-i-really-really-mean-it

The rados --all option already works correctly in that it only applies to the ls command.

I made the usage differently than the feature description:

rados purge <pool-name> --yes-i-really-really-mean-it

This is similar to the pool commands mkpool, cppool and rmpool which don't use the -p option to specify the pool name.
