CentOS6.5添加rbd模块

 [root@ceph-monitor opt]# modprobe rbd

  FATAL: Module rbd not found.

Once you have deployed the almighty CEPH storage, you will want to be able to actualy use it (RBD).

Since CEPH RBD module was first introduced with kernel 2.6.34 (and CentOS6.5 kernel is 2.6.32) – that means we need a newer kernel.

※0 当前内核版本

[root@ceph-monitor opt]# uname -r
2.6.32-431.el6.x86_64

※1 安装kernel-ml

[root@ceph-monitor opt]# rpm --import http://elrepo.org/RPM-GPG-KEY-elrepo.org
[root@ceph-monitor opt]# rpm -Uvh http://elrepo.org/elrepo-release-6-5.el6.elrepo.noarch.rpm

※2 修改/etc/grup.conf

If you want that new kernel to boot by default, edit /etc/grub.conf, and change the default=1 to default=0, and reboot

※3 加载并验证

[root@ceph-monitor opt]# modprobe rbd

[root@ceph-monitor opt]# lsmod | grep rbd
