Indeed using a containerized service, requires knowledge of it. It is just ridiculous to assume you do not. For me this cephadm is just a dead end. Most will choose their own container environment, and what then with this ceph? You have to maintain two different environments? You have to allocate resources between 2 different container environments, I cannot even imagine what complications that brings. > Also, future more running the upgrade, you > got > one line of text on the current progress, so I felt I was not in control > of > what happened. There is nothing wrong with that. If you have 5 years experience with podman/docker, you would feel more comfortable and in control. But you are here for using ceph (as everyone) not to acquire knowledge of a new container environment the cephadm team has chosen for you. > Currently, I run with the built packages for Debian and use the same > operating system and packages on all machines, and upgrading a cluster > is > as easy as running the apt update and apt upgrade.

Have you read recently that some people were updating software what made dockerd terminate all ceph daemons?

There are companies using thousands of osd's for years like CERN and NASA. They have been managing ok, most important is keep things simple. _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-le...@ceph.io
