CentOS - Apr 2012 - Centos 6 - Create raid 1 + LVM during gui install

Hi all,

Does any one know of a how to for creating raid 1 + LVMs during install for
Centos 6?

Do I create the physical LVM first and then raid or vise versa?

Its seems diff then doing it for Centos 5.

The way I did it was one drive at a time.


I did two, one for boot, the second was the OS

boot-
add a raid partition, did it for each drive, then make a raid device and 
select all both drives, /boot for mount point

OS-
added a raid partition for each drive, then when you make the raid 
device select physical volume as the file system type and both raid 
partitions you made for the OS.

then you hit create again and select volume group, select the raid 
device you want to play with.
you add mount points, these are your logical volumes...
/swap
/
/var
etc etc etc....

you cannot clone like you did in centos 5, so you must make the raid 
devices on each drive....a lot of deselecting and repetition....

to add a slave, you need to go through the motions, then edit your 
physical volume raid device....it will then allow you to make one a 
spare...until then the spare selection is greyed out...

hope this helps.
