关于lvm 关于udev 关于genkernel

jixiuf

/boot 挂在sda3
想把root分区挂到lvm 的逻辑分区上/dev/vg1/root上，出现错误，后来root挂到sda2上，也出现这个错误。   还是想实现root 挂到/dev/vg1/root上，所以像修改grub中选项（不用initrd命令，）的回复就不用回了。  我google.了一下，好像是udev 或者lvm2的bug，

另外，我没用hal ，不知有没有关系（估计不会，因为我在有hal的备份上，升级udev lvm2后，出现这个问题，没升级前，没这个问题，但问题在哪还是不清楚）

我猜：
你在initrd里面有用

1. vgchange -ay

复制代码

吧？

把它改成

1. vgchagen -av <vgname>/<rootlvname>

复制代码

那就只有/root才有警告。基本上因為你的logical volume是自己activate而不是udev做的你要手動制造symblic links...你也可以自己在initrd裡手動制造link（但我不知道怎樣在關機時delete掉link、因為那時候udev還會警告一次）。

這是無痛的警告。可以忽略。

自欺欺人的做法,隐藏
无痛,看着碍眼,看了下/etc/init.d/lvm
发现了/lib/rcscripts/addons/lvm-start.sh lvm-stop.sh
修改里面所有vg* lv* pv* 都 >/dev/null 2>/dev/null
眼不见心不烦
