[bglug] Problemi con Software RAID1 e LILO ... lungo

Scusate se disturbo, ma NON ne riesco proprio a venire a capo !

Ci sono 2 HD SCSI identici da 9.1 GB (hda e hdb) configurati con RAID 1
(mirroring) e suddivisi in 2 partizioni :
(raidtab.txt in allegato x chi vuole maggiori elementi)
/dev/md1 (sda1#sdb1) da 32 MB e montata come '/boot'/dev/md0 (sda2#sdb2) da
84xx MB e montata come '/'in LILO ho: (lilo.conf in allegato x chi vuole
maggiori elementi)boot=/dev/md1image=/boot/vmlinuz
	label=Linux
	initrd=/boot/initrd
	read-only
	root=/dev/md0

Vi informo che LILO precedentemente (6 -9 mesi va) funzionava ...ora non so
perche' non mi si installa e mi da ..."Fatal: Filesystem would be destroyed
by LILO boot sector: /dev/md1"

momentaneamente ho risolto in lilo con boot = /dev/fd0 (mi installa lilo sul
floppy) ma la cosa ovviamente e' MOLTO scomoda ...

In allegato trovate tutto quanto ho ritenuto potesse essere utile ...

Personalmente ho verificato che la tabella delle partizioni di /dev/md0
(devmd0.txt x chi vuole curiosare)
e' corretta (in effetti e' vuota e presenta solo il valore 55AA nei byte
finali)

mentre quella in /dev/md1 (devmd1.txt x chi vuole curiosare)
e' 'inconsistente' (sembrerebbe essere "fallata" e riempita di dati assurdi
... ovviamente le partizioni SpeedStor e Ontrack DM non son reali)

questo e' quello che mi sembra essere il post + interessante trovato con
Google:
http://www.cs.helsinki.fi/linux/linux-kernel/2002-26/0129.html

purtroppo NON mi posso permettere di fare prove (il server in questione e'
una macchina di produzione ... non posso permettermi un blocco...)

Ho trovato un'opzione con cui posso 'costringere' lilo a forzare
l'installazione nel boot-record, ma prima di farlo vorrei capire:
1) Perche' esiste quel boot record, chi l'ha creato e perche' non e' nullo
come quello di md0 ...
2) perche' prima lilo mi si installava senza problemi e dopo invece no?
Hanno per caso aggiunto qualche check + approfondito a lilo ?
3) c'e' modo di far girare GRUB su una partizione RAID1 ?

Grazie alla ml e scusate per il posto mega-lungo

Buon Lavoro

The number of cylinders for this disk is set to 2108512.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

The number of cylinders for this disk is set to 1116.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

Warning:  LINEAR is deprecated in favor of LBA32:  LINEAR specifies 24-bit
  disk addresses below the 1024 cylinder limit; LBA32 specifies 32-bit disk
  addresses not subject to cylinder limits on systems with EDD bios extensions;
  use LINEAR only if you are aware of its limitations.
