Ceph

I tried to create EC pool and provision rbd as following commands:

1. ceph osd erasure-code-profile set ecprofile k=4 m=2
2. ceph osd pool create rbd_ec 1024 1024 erasure ecprofile
3. ceph osd pool set rbd_ec allow_ec_overwrites true

1. ceph osd pool create rbd 1024 1024
2. ceph osd pool application enable rbd rbd --yes-i-really-mean-it
3. ceph osd pool application enable rbd cephfs --yes-i-really-mean-it
4. ceph osd pool application enable rbd rgw --yes-i-really-mean-it

1. rbd create --size 61440 --data-pool rbd_ec rbd/rbd-001 --image-format 2

the rbd create command have no response for more than 10 minutes.

but using the default setting for ec pool is fine to create rbd volumes:

1. ceph osd pool create rbd_ec 1024 1024 erasure
