Doug,

EVMS integrates all of this stuff together into one cohesive peice of 
technology.

But I agree, LVM should be modified to support RAID 1 and RAID 5, or MD 
should be modified to support volume management.  Since RAID 1 and RAID 
5 are easier to implement, LVM is probably the best place to put all 
this stuff.

User space issue. Its about the tools view not about the kernel drivers.

Not entirely true.  You could do everything in user space except online 
resize of raid0/4/5 arrays, that requires specific support in the md 
modules and it begs for integration between LVM and MD since the MD is 
what has to resize the underlying device yet it's the LVM that usually 
handles filesystem resizing.
