Hi Quentin
Did you check the pool was correctly created (Pg allocation)? Envoyé de mon Galaxy Ace4 Orange -------- Message d'origine -------- De : quentin.dore@xxxxxxxxxx Date :17/12/2015 19:45 (GMT+01:00) À : ceph-users@xxxxxxxxxxxxxx Cc : Objet : [Ceph] Not able to use erasure code profile Hello,
I try to use the default erasure code profile in Ceph (v0.80.9-0ubuntu0.14.04.2). I have created the following pool :
$ ceph osd pool create defaultpool 12 12 erasure
And try to put a file in like this :
$rados --pool=defaultpool put test test.tar
But I am blocked in the process and need a ctrl+c to end. Here is the debug information (debug ms = 5/5) :

But if I use a replicated pool, it works fine, I can put and get correctly the file using the same command.
Is there something particular to set in ceph.conf to be able to use erasure code plugin ? Sorry if it’s a newby question, but I start with ceph.
