Hello, Can someone please let me know what failure domain my erasure code pool is, osd or host? We thought we testing this by turning off 2 hosts, we have had one host offline recently and the cluster was still serving clients - did we get lucky? ceph osd pool get <pool> crush_rule crush_rule: ecpool ceph osd pool get <pool> erasure_code_profile erasure_code_profile: 6-2 rule ecpool { id 3 type erasure min_size 3 max_size 10 step set_chooseleaf_tries 5 step set_choose_tries 100 step take default step chooseleaf indep 0 type host step emit } ceph osd erasure-code-profile get 6-2 crush-device-class=hdd crush-failure-domain=osd crush-root=default jerasure-per-chunk-alignment=false k=6 m=2 plugin=jerasure technique=reed_sol_van w=8 octopus Regards Adam
