Kaleb,
Firstly the title is misleading as there was no heads up, a heads up is notice before you actually push the change, not when you do the change.
Ceph 14.x.x (Nautilus) will no longer be built on i686 and armv7hl archs starting in fedora-30/rawhide.
The upstream project doesn't support it. The armv7hl builders don't have enough memory (or address space) to build some components.
And the other active maintainer (branto) and I don't have cycles to devote to keeping it building on 32-bit archs.
(FWIW, currently ceph-12.2.9 (luminous) is in rawhide, f29, and f28 and it has packages for i686 and armv7hl for people who want to run ceph on 32-bit archs.)
As others have asked in the thread can we possibly build client only?
