I could be wrong however as far as I can see you have 9 chunks which
requires 9 failure domains.
Your failure domain is set to datacenter which you only have 3 of. So that
won't work.
You need to set your failure domain to host and then create a crush rule to
choose a DC and choose 3 hosts within

We're using the same ec scheme than yours with k=5 and m=4 over 3 DCs with the

Hello Torkil,
We're using the same ec scheme than yours with k=5 and m=4 over 3 DCs with the
