el9 build nautilus

23 Apr 2024

Hi,

I am looking for a bit of reassurance and guidance on running Nautilus with el9. I have applied a patch to rgw[2] and the ceph.spec[3]. I have managed to build ceph on a container with rocky9 using these commands[1]

I had to run the rpmbuild a few times, because it looks like the concurrent compiling causes some libraries/binaries not to be available on time. 

I can't really believe having so little issues with compiling that this could be problematic running in production. I even have the impression the changes between el8 and el9 are not really that significant. 

What could be bad about doing such upgrade? As a development team you should sort of know what is doable and what gives problems, not? I have tried to keep the set up as much standard as possible using rbd 3x replicated. If rgw and mds are unavailable for a while it would not be that much of an issue.

I was thinking of upgrading an osd node and check if there is any reporting on data being corrupted from this el9 node. Maybe reduce the amount of mgr / mon for a short while to only be on el7 nodes, although I can imagine that issues with monitor and manager would reveal themselves quickly when having one also on the el9 node.
