[reddef]

Bonjour,
j ai suivi pas à pas l' installation d'un raid 1mais j' ai eu ce message : mdadm: cannot open /dev/sda1: Device or resource busy comment faire sauvegarder tout mes répertoires et les ré installer. Merci d' avance

[Malekal_morte]

Salut,

On a aucune information.
Quelle distribution Linux ?
L'erreur apparaît Device or resource busy quand tu fais quoi ou à quelle occasion ?
Il y a quoi sur /dev/sda1 ?

Au minimum fournir :

Code : Tout sélectionner

fdisk -l

Il n'y a à priori aucun raid sur ce PC, vu que fdisk ne retourne pas de partition /dev/mdX
Faudrait voir ce que donne la commande mdadm
ou

cat /proc/mdstat

Il y a aussi un autre problème sur ton fdisk -l.
Tu dis que tu as un RAID 1, donc du miroir (cf https://www.malekal.com/raid-redondance-disques/ ).
et les disques /dev/sda et /dev/sdb sont totalement différentes.

Device Boot Start End Sectors Size Id Type
/dev/sda1 * 2048 1881602546 1881600499 897.2G 83 Linux
/dev/sda2 1881602547 1953520064 71917518 34.3G 82 Linux swap / Solaris

Device Start End Sectors Size Type
/dev/sdb1 2048 1881602546 1881600499 897.2G BIOS boot
/dev/sdb2 1881604096 1953523711 71919616 34.3G Linux swap

/dev/sda1 il y a une partition principale Linux
et un swap de 34 Go (ce qui est énorme)
Sur le /dev/sdb pas de partition Linux mais une partition de boot.

Tu ne peux pas faire de RAID 1 dans ces conditions.
Il faut installer Linux sur un des systèmes, puis copier les partitions de disques puis créer le RAID.

le dsque sda existait avant et fonctionnait,
sur partion;anager il y inscrit sur chaque disque sda et sdb linux member raid<
je fais court car je suis sur un live cd donc la commade mdadm ne fonctionne
Encore merci

Pour attacher une image, il faut utiliser l'éditeur avancé et attacher l'image en pièce jointe.

Pour créer un miroir, il faut suivre le tutoriel :
- Installer Linux sur un disque avec toutes les partitions dessus (toi tu as une partition Linux et Boot sur des disques différents)
- Copier la structure des partitions
- Utiliser mdadm pour créer le mirroir
