By reading this page from redhat:
https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Enterprise_Linux/5/html/Online_Storage_Reconfiguration_Guide/persistent_naming.html

We can learn that only /dev/disk/by-id/... (not /dev/sda or /dev/disk/by-path 
or /dev/disk/by-uuid) should be used in storage.config for safe reason.

 if you system is on /dev/sda and you put /dev/sda into storage.config, TS 
 will destroy the data on /dev/sda without any hesitate.
 this is proved to be true, please do not try, trust me.

Yeah, don't use e.g. /dev/sda. Use /dev/disk/by-uuid/...   or 
/dev/disk/by-path/...  or some such, and make sure you get it right. :)

I guess we could try to detect if a disk is in use, I don't know if there are 
any portable and reliable ways to detect that (but, I haven't looked). It's not 
as easy as looking via mount etc., you have to take into account various 
other disk managers, such as LLVM, or even just the software raid layers.
