I just added here 'class hdd'
rule fs_data.ec21 {
id 4
type erasure
min_size 3
max_size 3
step set_chooseleaf_tries 5
step set_choose_tries 100
step take default class hdd
step choose indep 0 type osd
step emit
}
somewhat off-topic, but: 2/1 erasure coding is usually a bad idea for the same reasons that size = 2 replicated pools are a bad idea.

This is normal when you change your crush and placement rules.
