[ceph-users] Best distro to run ceph.

I'm trying to set up a new ceph cluster, and I've hit a bit of a blank. I started off with centos7 and cephadm. Worked fine to a point, except I had to upgrade podman but it mostly worked with octopus. Since this is a fresh cluster and hence no data at risk, I decided to jump straight into Pacific when it came out and upgrade. Which is where my trouble began. Mostly because Pacific needs a version on lvm later than what's in centos7. I can't upgrade to centos8 as my boot drives are not supported by centos8 due to the way redhst disabled lots of disk drivers. I think I'm looking at Ubuntu or debian. Given cephadm has a very limited set of depends it would be good to have a supported matrix, it would also be good to have a check in cephadm on upgrade, that says no I won't upgrade if the version of lvm2 is too low on any host and let's the admin fix the issue and try again. I was thinking to upgrade to centos8 for this project anyway until I relised that centos8 can't support my hardware I've inherited. But currently I've got a broken cluster unless I can workout some way to upgrade lvm in centos7. Peter.
