Ceph » RADOS

When creating a EC pool:

ceph osd pool create poolio 128 128 erasure profile15

It returns

Error ENOENT: root item default does not exist

Which is indeed true here, but by design, because I have multiple roots for sas and ssd pools.

I worked around it by manually putting the rule for this pool in my crushmap:

rule poolio {
        ruleset 2
        type erasure
        min_size 3
        max_size 20
        step set_chooseleaf_tries 5
        step take default-ec
        step choose indep 0 type osd
        step emit
}
