在CentOS 5上编译内核版本> = 2.6.34：RAID设置“ddf1_foo”未激活？

我想在某些CentOS 5服务器上安装Ceph FS 。 由于ceph-fuse失败，出现以下错误：

 # ceph-fuse --no-fuse-big-writes -m 192.168.2.15:6789 /mnt/ceph/ ceph-fuse[7528]: starting ceph client ceph-fuse[7528]: starting fuse fuse: unknown option `atomic_o_trunc' 2013-04-04 13:51:21.128506 2b82d6e9e8f0 -1 fuse_lowlevel_new failed ceph-fuse[7528]: fuse finished with error 33 ceph-fuse[7526]: mount failed: (33) Numerical argument out of domain 

Google指出了这一点，但是内核2.6.18附带的CentOS 5.x，我要编译一个支持Ceph的更新的内核。

• 我第一次尝试使用ELRepo的kernel-lt 3.0.71
• 第二个是kernel.org的2.6.34.14

.config是从正在运行的内核复制2个附加设置：

 CONFIG_SYSFS_DEPRECATED_V2=y CONFIG_CEPH_FS=m 

但他们都给我以下错误：

• 从脚本检查yum连接？
• 作为用户启动Tomcat 7 – init.d脚本不能写入pid
• 什么可能导致一个Apache服务器locking“发送回复”进程？
• XenServer 6.2 SP1中的CentOS 7.0作为DomU; 不能与PV驱动程序一起运行？
• RHEL / CentOS – 是否可以将软件包更新至某个发布date？

第一个警告可以通过在提取内核映像并删除2行后编辑init脚本来解决：

 echo "Loading dm-region-hash.ko module" insmod /lib/dm-region-hash.ko

第二个错误怎么样：

 device-mapper: table: 253:0: mirror: Error creating mirror dirty log RAID set "ddf1_bar" was not activated 

• 2.6.18的初始化脚本： http : //fpaste.org/byZ3/
• 2.6.34.14's： http ://fpaste.org/8COr/

它们大部分是相同的，只是下面的模块没有加载到新的内核中：

 echo "Loading dm-mem-cache.ko module" insmod /lib/dm-mem-cache.ko echo "Loading dm-message.ko module" insmod /lib/dm-message.ko echo "Loading dm-raid45.ko module" insmod /lib/dm-raid45.ko 

这是RAID set "ddf1_foo" was not activated吗？

类似于“镜像日志：镜像日志：2的无法识别的同步参数”，“表：镜像：创build镜像脏日志时出错”的奇怪的错误消息意味着您的内核设备映射器和用户空间工具版本不匹配：可能是您的内核太近你的版本的lvm工具。 从源安装最新的设备映射器和lvm2，它应该工作。

我试图编译最新版本的LVM2 ：

 # /usr/sbin/lvm version LVM version: 2.02.98(2) (2012-10-15) Library version: 1.02.67-RHEL5 (2011-10-14) Driver version: 4.11.6 

但没有什么变化。

在源文件夹中search，我发现这个：
