最近发现suse11sp2的系统解决了异常死机的问题之后，又引入了另外的问题，比如这次的lv不能自动激活，问题一个接一个啊。
1、lv可以手动激活，但是不能自动激活
dcoadbpro:~ # lvdisplay
--- Logical volume ---
LV Name /dev/dcoadbpro_lv/lvol0
VG Name dcoadbpro_lv
LV UUID XejtSI-ifla-NJgl-SfkO-KKlq-jRme-eI5Ivt
LV Write Access read/write
LV Status NOT available
LV Size 990.00 GiB
Current LE 253440
Segments 1
Allocation inherit
Read ahead sectors auto
dcoadbpro:~ # vgchange -ay dcoa_lv
dcoadbpro:~ # lvdisplay
--- Logical volume ---
LV Name /dev/dcoadbpro_lv/lvol0
VG Name dcoadbpro_lv
LV UUID XejtSI-ifla-NJgl-SfkO-KKlq-jRme-eI5Ivt
LV Write Access read/write
LV Status available
LV Size 990.00 GiB
Current LE 253440

dcoadbpro:~ #

2、检查boot.lvm是否开机启动
dcoadbpro:~ #
dcoadbpro:~ #
dcoadbpro:~ # chkconfig -A | grep boot.lvm
boot.lvm off
boot.lvm_monitor on
dcoadbpro:~ # chkconfig boot.lvm on
dcoadbpro:~ # chkconfig -A | grep boot.lvm
boot.lvm on
boot.lvm_monitor on
dcoadbpro:~ #reboot
dcoadbpro:~ # lvdisplay
--- Logical volume ---
LV Name /dev/dcoadbpro_lv/lvol0
VG Name dcoadbpro_lv
LV UUID XejtSI-ifla-NJgl-SfkO-KKlq-jRme-eI5Ivt
LV Write Access read/write
LV Status NOT available
LV Size 990.00 GiB
Current LE 253440

3、在/etc/init.d/目录中新增加一个after.local脚本
具体操作如下：
1)．如果/etc/init.d/after.local文件本身不存在，请执行 cp /etc/init.d/boot.local /etc/init.d/after.local 命令创建。
2)．vi after.local编辑此文件，将其中所有非注释语句都删除，并且在文件中添加/etc/init.d/boot.lvm start 这样一行语句，保存退出
3).重启操作系统,再检查lv的状态,发现lv已经自动激活，到此，问题解决。
