Hi Ishmael You have to apply correct client.keyring permission to a pool on which you trying to create rbd image. >From Admin/Management Node: - create a client keyring. 1. Admin Node:-- ceph auth get-or-create client.rbd mon 'allow r' osd 'allow rwx pool=PoolA' [client.rbd1] key = AQB2kVpXjhq9OBAACIHEUeRs04UqJsbQeNyLRg== 2. Get the keyring from auth list and push the keyring to client node. -- ceph auth get-or-create client.rbd | ssh user@clientA1 sudo tee /etc/ceph/ceph.client.rbd.keyring [client.rbd1] key = AQB2kVpXjhq9OBAACIHEUeRs04UqJsbQeNyLRg== 3. From client Node cat /etc/ceph/ceph.client.rbd.keyring >> /etc/ceph/keyringceph -s --name client.rbd user@client:$ rbd create PoolA/PoolA_image1 -S 100G --image-format 2 --object-size 32K --image-feature layering --name client.rbduser@client:$ sudo rbd map --image PoolA/PoolA_image1 --name client.rbd/dev/rbd0 -- Rakesh Parkiti ---------- Forwarded message ---------- From: Ishmael Tsoaela <ishmae...@gmail.com> Date: Fri, Jun 17, 2016 at 5:31 PM Subject: [ceph-users] image map failed To: ceph-users@lists.ceph.com
