Upgrading from Mimic to Nautilus
Hi, How is the experience of upgrading from Mimic to Nautilus? Anything to watch out for? And is it a smooth transition for the ceph-fuse clients on Mimic when interacting with a Nautilus MDS? I'm reading the docs on https://docs.ceph.com/docs/nautilus/install/upgrading-ceph/ and it looks pretty straightforward. I'm currently on Mimic 13.2.8, and have been putting off upgrading to Nautilus, but I think it's time. Thanks in advance, -Paul Choi
So, the thing that seems to cause all the problems is not doing: ceph osd require-osd-release nautilus as that is associated with this bug: https://tracker.ceph.com/issues/44184 which can be distressing if you make new pools. I found that ceph-ansible didn't seem to do this for my cluster using the rolling_upgrade playbook, and I'm not sure why... so be careful if automating your upgrade. (If you follow the manual steps, then you'll do that when you get to it anyway, but it's worth mentioning how important it is)
Thanks for the heads up! Hoping to try it the upgrade from Mimic to Nautilus in the next couple of months... (fingers crossed).
