I was trying to decompile and edit the CRUSH map to adjust the CRUSH
rules. My first attempt created a map that would decompile, but I
could not recompile the CRUSH even if didn't modify it. When trying to
download the CRUSH fresh, now the decompile fails.
[root@nodezz ~]# ceph osd getmap -o map.crush
got osdmap epoch 12792
[root@nodezz ~]# crushtool -d map.crush -o map
terminate called after throwing an instance of 'ceph::buffer::malformed_input'
what(): buffer::malformed_input: bad magic number

Aborted
map.orig is the first map that would not compile even without edits.
map.crush is the file that would not decompile.
Any ideas?
