No trabaja con *grub.  Con REDADA y también *LVM, /la bota tiene que ser en
una partición regular.
Aquí *LVM es el problema, no REDADA-1.

Con REDADA-1 *via *md y ningún *LVM, /bota en un *mirrored *ext3/*ext4

Me preguntaba sobre aquello. También, los puntos de carta de la bota a un específico *kernal. Qué hace aquello consigue actualizado con REDADA 1?

At one time there was a problem having /boot on raid, and its been a

With lilo it works fine, but I don't know about grub.

It doesn't work with grub.  With RAID and also LVM, /boot has to be on a
regular partition.
Here LVM is the problem, not RAID-1.

With RAID-1 via md and no LVM, /boot on a mirrored ext3/ext4
filesystem definitively works with grub. We use it since several
years, and had enough disk errors to prove it working. One needs to
take care that grub bootloader is installed on both disks, though,
openSUSE doesn't do this itself during installation. Extra
robustness comes with stanzas that name both disks, in case hd0 is
not visible to the BIOS any more and hd1 suddenly gets hd0.

I was wondering about that. Also, the boot menu points to a specific kernal. How does that get updated with RAID 1?
