HI all,
Recently I was playing with crushmaps. I would like to know the difference
between step choose and step chooseleaf.
when I used :
ruleset rule1{
...
step take default
step choose firstn 0 host
step emit
}
And I tested above using crushtool, it returned ids of bucket host.
But when I used it in cluster, it chose osds.
If this works to get devices, then why we need chooseleaf.
Regards
Sahana.
