 Posted: Sun Nov 27, 2005 9:48 am Post subject: [PARTITIONNEMENT] migration de table freebsd -> linux |
 |
|
Bonjour,
j'avais une machine en dual boot
| Code: |
hda = gentoo
hde sur primaire MB UDMA66 qui était sous freebsd
hdf = data gentoo
hdg = data gentoo |
Je tente de réutiliser le hde pour reformater tout le disque et le passer en ext3 dans le but d'y installer le systeme à terme.
au fdisk je n'arrive pas à ecrire ma partition sans aucun message d'erreur (pareil avec cfdisk)
Pour info :
| Code: |
# fdisk -l
Disk /dev/hda: 10.2 GB, 10239860736 bytes
16 heads, 63 sectors/track, 19841 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 1 204 102784+ 83 Linux
/dev/hda2 205 1245 524664 82 Linux swap / Solaris
/dev/hda3 1246 19841 9372384 83 Linux
Disk /dev/hde: 251.0 GB, 251000193024 bytes
255 heads, 63 sectors/track, 30515 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk /dev/hde doesn't contain a valid partition table
Disk /dev/hdg: 163.9 GB, 163928604672 bytes
255 heads, 63 sectors/track, 19929 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hdg1 1 19929 160079661 83 Linux
Disk /dev/hdh: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hdh1 1 19457 156288321 83 Linux

J'ai fait un smartctl qui ne me signale aucun pb.
Le DMESG reste desespérement vide aussi en dehors des infos physique sur le disque au boot (normal...)
Comment faire pour réinitialiser cette ^$ù*$ç de table de partition ?
| Code: |
# fdisk /dev/hde
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.
The number of cylinders for this disk is set to 30515.
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: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
mamachine ~ # fdisk /dev/hde

le DMESG affiche laconiquement
| Code: |
hde: unknown partition table
hde: unknown partition table

Quelq'un a une idée ??? tous les posts que j'ai trouvé sur ce sujet avait un moment ou à un autre un message d'erreur
Merci d'avance |

Ton disque étant partionné au format BSD (et pas DOS comme utilisé par linux), fdisk ne le connait pas.
L'option "o" de fdisk (o créer une nouvelle table vide de partitions DOS) devrait t'aider grandement :
| Code: | fdisk /dev/hde
o
n
etc..

Merci mais...
A priori sans effet...
de même que le cfdisk -z ...
