Hi Dan, I seem to have a problem finding correct release notes and upgrade instructions on the ceph docs. If I open https://docs.ceph.com/en/pacific/ and go to "Ceph Releases", pacific is not even listed even though these doc pages are supposedly about pacific. I also can't find the "upgrading from nautilus or octopus" pages anywhere. If I go to v:latest, I can see such information. Is there a link error that, when selecting version pacific shows the pages for octopus? This would be very confusing, because the link "https://docs.ceph.com"; forwards to "https://docs.ceph.com/en/pacific/"; which would show information on octopus.

This was noticed in https://lists.ceph.io/hyperkitty/list/ceph-users@xxxxxxx/thread/7KSPSUE4VO274H5XQYNFCT7HKWT75BCY/ If you are not using cephadm, you must disable FSMap sanity checks *before starting the upgrade*: ceph config set mon mon_mds_skip_sanity 1 After the upgrade is finished and the cluster is stable, please remove that setting: ceph config rm mon mon_mds_skip_sanity Clusters upgraded by cephadm take care of this step automatically.
