Re: [Rdo-list] Problem with Cinder (Juno) and Ceph

The maintainers of the package for CentOS didn't compiled it with rbd support. I recompiled it with the rbd option and it was working propery. You also need to use the CentOSPlus repo for rbd kernel support.

Reading the RDO documentation, at point 4 of "Install Virtualization for Ceph Block Devices" tells: Older releases of RHEL and CentOS don't provide the rbd format required for use with Ceph. Now, I think: Centos7 isn't a older release. But the execution of "qemu-img -f", give me: vvfat vpc vmdk vhdx vdi sheepdog sheepdog sheepdog raw host_cdrom host_floppy host_device file qed qcow2 qcow parallels nbd nbd nbd iscsi gluster gluster gluster gluster dmg cow cloop bochs blkverify blkdebug There isn't "rdb"....
