RedHat - Howto mirror boot disk using LVM
 
Hi,
I have my LogVol00 with 2 disks.
/dev/sda ...primary boot
/dev/sdc ...newdisk

I have initiated /dev/sdc using "pvcreate /dev/sdc" and after "vgextend LogVol00 /dev/sdc".

Now I want mirror /dev/sdc and making bootable.

How I can do that?

On HP-UX I use lvextend -m 1 "logicalvolumes" "disk"

On RH I dont know!
