The demand for LTS - at least in our case - does not stem from unprofessionalism or biased opinion. It's the desire to stay up to date on security patches as much as possible while maintaining a well tested and stable environment. Both Pacific and Octopus (we’re currently on Nautilus) have some problems within themselves that made us not upgrading our cluster. The latest releases felt kind of rushed out rather than well tested. We (the LTS „faction“) still would like to keep up with security and minor patches on the cluster. We’re not talking about backporting new features.

[ceph-users] Re: Brand New Cephadm Deployment, OSDs show either in/down or out/down
Debian 10 is not on the recommended platform list for Ceph.
Maybe a problem due to the change from sysvinit to systemd?
