Sybase install info :
Sybase master: /dev/raw/raw24
Sybase procs : /dev/raw/raw25
在build的时候提示：
Warning : Unable to verify /dev/raw/raw24 device size.Please verify that this device is no already in user and that is has sufficient space available.
Warning : Unable to verify /dev/raw/raw5 device size.Please verify that this device is no already in user and that is has sufficient space available.
忽略warning后，继续后安装信息如下：
Building Adaptive Server 'DBServer':

不知道为什么在用/dev/raw24或raw25的时候会有这样的提示，并导致安装失败。
如果用如下安装;
Dataserver master path : /dev/mapper/system-dbmaster
Dataserver procs path : /dev/mapper/system-dbprocs
的话安装是成功的，但是reboot后，所有的LV在 mtab中mount不成功了，并无法进入系统了。
问题有两个：
1、为什么用/dev/raw/raw24 /dev/raw/25的时候会有警告，并且安装不成功？如何解决？
2、为什么用/dev/mapper/system-dbmaster /dev/mapper/dbprocs sybase安装成功，但是reboot后LVmount不成功？如何解决？
