Description

Right now we can specify the failure domain via

ceph osd erasure-code-profile set ec86 \
  plugin=jerasure \
  k=8 \
  m=6 \
  osd-failure-domain=host

It would be nice if two-step rules could be created a la

ceph osd erasure-code-profile set ec86 \
  plugin=jerasure \
  k=8 \
  m=6 \
  osd-failure-domain=host:4,osd:4

That results in

"rule ecpool-86 {
    id 86
    type erasure
    step set_chooseleaf_tries 5
    step set_choose_tries 100
    step take default class hdd
    step choose indep 4 type host
    step chooseleaf indep 4 type osd
    step emit
}"
