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
