Hi All,
I'm trying to add a crush rule to my map, which looks like this:
rule rack_ruleset {
ruleset 1
type replicated
min_size 1
max_size 10
step take default
step choose firstn 2 type rack
step chooseleaf firstn 2 type host
step emit
}
I'm not configuring any pools to use the ruleset at this time. When I
recompile the map, and test the rule with crushtool --test, everything
seems fine, and I'm not noticing anything out of the ordinary.
But, when I try to inject the compiled crush map back into the cluster like
this:
ceph osd setcrushmap -i /path/to/compiled-crush-map
The monitor process appears to stop, and I see a monitor election
happening. Things hang until I ^C the setcrushmap command, and I need to
restart the monitor processes to make things happy again (and the crush map
never ends up getting updated).
In the monitor logs, I see several segfaults that look like this:

I'm running ceph 0.80.5-1trusty on Ubuntu 14.04 with
kernel 3.13.0-35-generic.
Anyone have any ideas as to what is happening?
-Steve
