ceph-16.2.7 in fedora rawhide — built with fmt-8.0.1 — apparently worked for a few days between 29 Dec. and 7 Jan.,
When fmt was updated in fedora rawhide on 7 Jan to fmt-8.1.1, libvirt users reported a crash[1] due to an undefined symbol reference (fmt::v8::detail::error_handler::on_error(char const*)) in libcephfs.so.2.
ceph-16.2.7 has since been rebuilt[2] with fmt-8.1.1. We are waiting for the libvirt team to test the new build to confirm.

fmt 8.1.0 does have regression in ABI from 8.0.0, but it was fixed in
8.1.1. See https://github.com/fmtlib/fmt/issues/2695
But could you elaborate why it requires recompiling ceph? (from fmt
7.x to 8.x, or just from 8.0.0 to 8.1.1 without changing the soname).
