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?

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 a

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

Loic,
So, if want have a failure domain by host, I’ll need set up a erasure profile
which k+m = total number of hosts I have, right?

Hello,
I’ve take a look to this documentation (which help a lot) and if I understand
right, when I set a profile like:
===
ceph osd erasure-code-profile set isilon k=8 m=2 ruleset-failure-domain=host
===
And create a pool following the recommendations on doc, I’ll need (100*16)/2 =
800 PGs,
Hi,
Thanks for the update : good news are much appreciated :-) Would you have time
to review the documentation at https://github.com/ceph/ceph/pull/3194/files ?
It was partly motivated by the problem you had.
Cheers

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,
The 2147483647 means that CRUSH did not find enough OSD for a given PG. If you
check the crush rule associated with the erasure coded pool, you will most
probably find why.

Hello,
I'm trying to create an erasure pool following
http://docs.ceph.com/docs/master/rados/operations/erasure-code/, but when I try
create a pool with a specifc erasure-code-profile ("myprofile") the PGs became
on incomplete state.
Anyone can help me?
Below the profile I created:
