If you learn only the basics, you will probably fuck up when you have some sort of real issue with ceph. I would not recommend sticking to basics of anything with this install, it is not like if something goes wrong you restore a vm from a snapshot or so. > Pros: > + cephadm works very easy.

If you proceed to use ceph in a manner where you do not know what you are doing, you ‘risk’ losing your clients data. > + Upgrading a manual installation is very tricky! Cephadm manages > upgrades of ceph automatically. You only need to give the command (done > it already two times). Why is this tricky? Just read the guidelines and understand them. I would even argue that you need to know how to update ceph manually. So you are better prepared for what happens at stages of the update. > + If you need to upgrade your OS, will the manual installation still > function? With cephadm the ceph processes inside the docker containers > experience minimal impact with the upgrade of the os (dind't do an OS > upgrade yet, but had this issue with other applications). > If you need to use cephadm because you can't work with ceph manually, just forget about using ceph. (and forget about this docker, do this podman if you have to) _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-le...@ceph.io
