Hi, loic:
I saw you had published a new version(v1.0.33) of "python crush" .
And then I test it used my crushmap.
I am glad to tell you that the "optimize" command have worked well.
when I used the following command such as:
crush optimize --crushmap report.json --out-path optimized.crush
--rule replicated_ruleset --pool 49
There was no error output anymore. And after that I import the
optimized crushmap to my cluster, after rebalancing all the OSDs are
+-0.9 over/under filled.
when I used the "compare" command, there was an error in output:
crush compare --rule replicated_ruleset --replication-count 2
--origin /tmp/report.json --destination optimized.crush
Traceback (most recent call last):
File "/usr/bin/crush", line 25, in <module>

line 716, in set_compat_choose_args
assert choose_args_name

After that, I got the report of my cluster and "optimize" it once
again, there still have an error in output:
ceph report > report.new.json
crush optimize --crushmap report.json --out-path optimized.crush
--rule replicated_ruleset --pool 49
[root@node-4 ~]# crush optimize --crushmap report.json --out-path
