LVM vs RAID Concepts
-
If the machine is to be installed with the LVM means we are cheating the OS to be installed in the Single HDD where the partition size can be increased further in future.
But if the RAID comes in the same path or not ?
If i am installed any linux OS in disk 1 and extended the new paritition in disk 2.Once the disk 1 got issue in booting or the hard disk has bad sector and unable to boot,i am in need of the Disk 1 data whether it is possible ??

@Lakshmana Horrible translation issues here it looks like.
It's not LVM vs RAID. It's LVM and RAID (generally).

This is called a span. It's generally a bad idea because you are skipping RAID reliability AND taking on new risks and getting no extra performance. The one offset to this, and it is trivial, is that if one device fails then any data remaining on the other disk can be recovered in most cases (but it is a recovery, it does not "just work") but you have zero control over what data goes where, what data is split between the two devices, and such.
This is considered a standard new administrator mistake to do this for any reason involving reliability. It's a bad, bad idea.

In most cases, RAID goes underneath LVM. But you can build RAID on top of it as well. And LVM now has RAID built into it, too.

I meant to get more information than my initial post here, but my distraction appears to not have mattered.
