has anybody encountered the same problem? Zhenshi Zhou <deaderzzs@gmail.com> 于2020年5月9日周六 下午3:21写道：

Hi all,

I'm deploying a new octopus cluster using cephadm, follow docs <https://ceph.io/ceph-management/introducing-cephadm/>. However it failed on the bootstrap step. According to the logs, key generating failed because of the lack of directory and file. Did I miss something?

here is the logs: [root@ceph-mon1 ~]# cephadm bootstrap --mon-ip 172.24.202.119 INFO:cephadm:Verifying podman|docker is present... INFO:cephadm:Verifying lvm2 is present...
