[linux-lvm] Does LVM2 support RAID?

[Rocky Lee]

Hello all 

Happy Chinese New Year to you!
and thanks for reading my issues.

Here's my question about LVM1 and LVM2

LVM1+ MD is good methd to support backup and data recovery of data.
I found some documents said that LVM2 already can support disk protection and data recovery.
does it mean that LVM2 including various raid algorithms ? or other features?

How they work?

If I use LVM2 will be better than use LVM1 + MD?

Thank you
Have a nice day
                            Rocky Lee
