Thanks for your answer. But another doubt raised…
Suppose I have 4 hosts with a erasure pool created with k=3, m=1 and failure
domain by host and I lost a host. On this case I’ll face with the same issue on
the beginning of this thread because k+m number of hosts, right?

Hello Loic,
Thanks for you help, I’ve take a look to my crush map and I replace step
chooseleaf indep 0 type osd” by step choose indep 0 type osd” and all PGs was
created successfully.

Hi,
Thanks for the update : good news are much appreciated :-) Would you have time

which k+m = total number of hosts I have, right?

Yes, k+m has to be = number of hosts.

On Wednesday,
Understood.
Thanks for your help, the cluster is healthy now :D
Also, using for example k=6,m=1 and failure domain by host I’ll be able lose
all OSD on the same host, but if a lose 2 disks on different hosts I can lose
data right? So, it is possible been a failure domain which allow me to lose

I'm trying to create an erasure pool following

Anyone can help me?
Below the profile I created:

check the crush rule associated with the erasure coded pool, you will most
probably find why.
