Is it poosible to provide instructions about upgrading from CentOs7+ ceph 14.2.8 to CentOs8+ceph 15.2.0 ?
You have ~2 options:
- First, upgrade Ceph packages to 15.2.0. Note that your dashboard will break temporarily. Then, upgrade each host to CentOS 8. Your dashboard should "un-break" when the el8 ceph packages are installed.
- Combine the Ceph upgrade with a transition to cephadm based on these directions:
https://docs.ceph.com/docs/octopus/cephadm/adoption/
After the transition, you can either stick with el7 indefinitely (cephadm doesn't care too much about the host OS) or upgrade the host to centos8.
- First upgrade each host to CentOS8, then upgrade Ceph. This will eventually be possible, but at the moment we don't have el8 packages built for nautilus. :/
as far as I know, please let me be wrong, there is no upgrade path from CentOS 7 to 8. One has to do a new installation, right?
