Hola gente.. |
| 2 |
|
| 3 |
sigo pegándome con la nueva instalación.. |
| 4 |
|
| 5 |
el problema ahora es que no me arranca la partición root.. seguramente |
| 6 |
me halla olvidado algo.. pero no encuentro que puede ser. |
| 7 |
|
| 8 |
los síntomas son: |
| 9 |
------------------------------------ |
| 10 |
1) lilo arranca bien |
| 11 |
2) arranca el kernel y aparece todo el log de arranque del kernel |
| 12 |
3) mensaje de kernel panic: |
| 13 |
kernel pannic - not syncing: VFS |
| 14 |
unable to mount root fs on unkown block (8,19) |
| 15 |
|
| 16 |
3.1) si arranco con un genkernel, el mensaje que me sale es: |
| 17 |
Block device /dev/sdb3 is not a valid root device.. |
| 18 |
The root device is unespecified or not detected. |
| 19 |
------------------------------------ |
| 20 |
|
| 21 |
|
| 22 |
en principio está todo correcto: |
| 23 |
LILO |
| 24 |
------------------------------------ |
| 25 |
# los dd arrancan bien o si no no arrancaría el kernel |
| 26 |
# el lilo está bien configurado: |
| 27 |
## este para el kernel hecho a mano: |
| 28 |
image = /boot/kernel-2.6.16-gentoo-r9 |
| 29 |
root=/dev/sdb3 |
| 30 |
label=produc-2.6.16 |
| 31 |
read-only |
| 32 |
|
| 33 |
## este para el genkernel: |
| 34 |
image = /boot/kernel-genkernel-x86-2.6.16-gentoo-r9 |
| 35 |
label=genkernel |
| 36 |
read-only |
| 37 |
root=/dev/ram0 |
| 38 |
append="init=/linuxrc ramdisk=8192 real_root=/dev/sdb3 udev" |
| 39 |
initrd=/boot/initramfs-genkernel-x86-2.6.16-gentoo-r9 |
| 40 |
|
| 41 |
sí que es verdad que el lilo me salta algún error pero he visto en |
| 42 |
google que se pueden obviar [1]. |
| 43 |
|
| 44 |
------------------------------------ |
| 45 |
|
| 46 |
MOUNT |
| 47 |
------------------------------------ |
| 48 |
Montar el sdb3 desde el live cd no me dá ningún problema: |
| 49 |
# mount /dev/sdb3 /mnt/gentoo/ |
| 50 |
# mount | grep sdb3 |
| 51 |
/dev/sdb3 on /mnt/gentoo type ext3 (rw) |
| 52 |
------------------------------------ |
| 53 |
|
| 54 |
KERNEL |
| 55 |
------------------------------------ |
| 56 |
Creo que el kernel lo tengo bien configurado para dar soporte a ext3: |
| 57 |
<*> Second extended fs support |
| 58 |
|
| 59 |
|
| 60 |
[ ] Ext2 extended attributes |
| 61 |
|
| 62 |
|
| 63 |
[ ] Ext2 execute in place support |
| 64 |
|
| 65 |
|
| 66 |
<*> Ext3 journalling file system support |
| 67 |
|
| 68 |
|
| 69 |
[ ] Ext3 extended attributes |
| 70 |
|
| 71 |
|
| 72 |
[ ] JBD (ext3) debugging support |
| 73 |
------------------------------------ |
| 74 |
|
| 75 |
FSTAB: |
| 76 |
------------------------------------ |
| 77 |
livecd linux # cat /etc/fstab |
| 78 |
|
| 79 |
# <fs> <mountpoint> <type> <opts> <dump/pass> |
| 80 |
/dev/sdb1 /boot ext2 noauto,noatime 1 1 |
| 81 |
/dev/sdb3 / ext3 noatime 0 0 |
| 82 |
/dev/sdb2 none swap sw 0 0 |
| 83 |
/dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,ro 0 0 |
| 84 |
none /proc proc defaults 0 0 |
| 85 |
none /dev/shm tmpfs nodev,nosuid,noexec 0 0 |
| 86 |
------------------------------------ |
| 87 |
|
| 88 |
|
| 89 |
No sé que más probar.. |
| 90 |
Cualquier sugerencia es bien venida. |

The kernel was compiled with DEVFS_FS, but 'devfs=mount' was omitted |
| 106 |
as a kernel command-line boot parameter; hence, the '/dev' directory |
| 107 |
structure does not reflect DEVFS_FS device names. |
