This does the heavy lifting of installing and configuring machines. I partition the boot disks, install the OS, then Chef does everything after that. It works, but there's no cluster wide automation. For example, it won't handle major Ceph upgrades. A major upgrade has the steps: 1. Update packages 2. Restart all monitors 3. Restart all osds 4. Restart all MDS/RadosGW Chef doesn't handle that. It's only aware of the individual nodes, so it'll restart the monitors, osds, mds, and radosgw without regard for the other nodes. I'm sure I could add the logic, but it's a lot of work to make it work correctly in all cases. I just do the upgrades by hand. This isn't unique to Chef. cfEngine, Puppet, Chef, and Salt all have the same limitations. Ansible claims to be cluster aware, but I haven't really seen any actual support for that statement. I am a recent convert to Config Management. I might be a bit of a zealot, but I don't plan to manage nodes by hand ever again. -- *Craig Lewis* Senior Systems Engineer Office +1.714.602.1309 Email clewis at centraldesktop.com <mailto:clewis at centraldesktop.com> *Central Desktop.
