Aquí *LVM es el problema, no REDADA-1.

Con REDADA-1 *via *md y ningún *LVM, /bota en un *mirrored *ext3/*ext4
*filesystem definitivamente trabajos con *grub. Lo utilizamos desde varios
años, y tuvo bastantes errores de disco para probarlo laborable. Uno necesita cuidar que *grub *bootloader es instalado en ambos discos, aun así,
*openSUSE  no  esto él durante instalación. La Robustez
extra viene con *stanzas que nombra ambos discos, en caso *hd0 no
es visible al BIOS más y *hd1 de repente consigue *hd0.


Quizás alguien tendría que hacer un *HOWTO en esto. Yo recientemente montado un *server en trabajo con REDADA 4 puesto que la mayoría de el sistema, pero /la bota no es en REDADA. Si había sabido sobre esto lo habría hecho.

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.


Perhaps someone should do a HOWTO on this. I recently set up a server at work with RAID 4 for most of the system, but /boot is not on RAID. If I'd known about this I would have done it.
