Hello,
I am currently doing some erasure code tests in a dev environment.
I have set the following by "default"
rule sas {
ruleset 2
type erasure
min_size 3
max_size 13
step set_chooseleaf_tries 5
step set_choose_tries 100
step take fourtb
step choose indep 0 type osd
step emit
}
As I am splitting the file into 13 chunks it is placing these across 13
different OSD's.
In the DEV environment I do not have 13 hosts to do full host replication,
however I am sure I can change the crush map rule to try and split evenly
across the 4 HOST I have.
I'm think I will need to tell it to pick 4 HOST's, and then the second line to
pick OSD's, however as 13 does not divide by 4 exactly what would be the best
way to lay out this crushmap rule?
Thanks,
Ashley
