Thanks , as i understand format spec does not exists? Does somebody
can send me binary crushmap file to experiment?
(i known that i can create it via installing ceph on my system, but why not?=))
Also i'm read about json format in google, but don't find it formal
spec. Ceph python module works with
{ "trees": xxxx }, some info i found in email lists and some says
about { "buckets": xxx, "rules": xxx}.
My goal - bring up pure crushmap parser (text, binary, json) to golang
and use it with go based crush.
