I gather that corosync.h should be part of the corosync-devel package for F-10, but it seems to be missing. Can you do a new package to add this file, or is it more involved than that?
I gather that there is or is about to be a rawhide release which fixes this. Also, the requirement for building gfs_controld has gone away since I see that dct has beaten me to it. Will wait for rawhide to stabilise a bit and then try that.
