I have CentOS 6.4 running with the 3.11.6 kernel from elrepo and it includes the rbd module. I think you could make the same update on RHEL 6.4 and get rbd. From there it is very simple to mount an rbd device.
Here are a few notes on what I did. Update kernel: sudo rpm --import
http://elrepo.org/RPM-GPG-KEY-elrepo.org sudo rpm -Uvh
http://elrepo.org/elrepo-release-6-5.el6.elrepo.noarch.rpm sudo yum -y update sudo yum -y --enablerepo=elrepo-kernel install kernel-ml sudo vim /boot/grub/menu.lst (update default to zero)
reboot Create rbd device: rbd create {name} --size {size_in_MB} sudo modprobe rbd sudo rbd map {name} --pool {pool_name} Device appears at /dev/rbd/rbd/name From: ceph-users-bounces@xxxxxxxxxxxxxx [mailto:ceph-users-bounces@xxxxxxxxxxxxxx]
On Behalf Of alistair.whittle@xxxxxxxxxxxx Now that my ceph cluster seems to be happy and stable, I have been looking at different ways of using it. Object, block and file. Object is relatively easy and I will use different ones to test with Ceph. When I look at block, I’m getting the impression from a lot of Googling that deploying clients on Red Hat to connect to a Ceph cluster can be complex. As I understand it, the rbd module is not currently in the Red Hat
kernel (and I am not allowed to make changes to our standard kernel as is suggested in places as a possible solution). Does this mean I can’t connect a Red Hat machine to Ceph as a block client? _______________________________________________ This message is for information purposes only, it is not a recommendation, advice, offer or solicitation to buy or sell a product or service nor an official confirmation of any transaction.
