谷歌指出this但CentOS 5.x附带内核2.6.18,我将编译一个支持Ceph的新内核.

.config从正在运行的内核中复制了2个额外的设置：
CONfig_SYSFS_DEPRECATED_V2=y CONfig_CEPH_FS=m
但他们都给我以下错误：
在提取内核映像并删除2行后,可以通过编辑init脚本来消除第一个警告：
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init脚本：http://fpaste.org/byZ3/
> 2.6.34.14：http://fpaste.org/8COr/
它们大致相同,只是以下模块未加载到较新的内核中：
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设置“ddf1_foo”未激活的原因吗？

A strange error message similar to “mirror log: unrecognised sync
argument to mirror log: 2”,“table: mirror: Error creating mirror
dirty log” means you have mismatched kernel device mapper and
userspace tools versions: probably your kernel is too recent for your
version of the lvm tools. Install the latest device mapper and lvm2
from sources,and it should work.
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
但没有变化.
