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.
I've had good luck with the Ubuntu LTS releases - no need to add extra repos. 20.04 uses Octopus. On Fri, Apr 30, 2021 at 1:14 PM Peter Childs <pchilds@bcs.org> wrote:

Yes I think the debate might be debian vs Ubuntu. We've been a bit of a CentOs shop but with red hat removing some of the support for last gen high end hardware, and the issues with centos8 stream. We may just need to keep our eyes open. Don't get me wrong I'm using last gen hpc kit so it's not bad kit, it's just not new either. Peter.
