raid10 changement de configuration ?
Bonjour à tous,
N'étant pas un expert de la gestion du raid, j'en appelle à vos lumières.
J'ai créé un raid10 à l'installation d'une debian wheezy.
Régulièrement deux disques sortent du raid, voire quand ça reboote, je
vois un nouveau raid de créé (md127) sans savoir d'où ça vient.
Savez-vous ce que je peux regarder pour comprendre où ça pose pb et
comment faire pour obtenir un raid fonctionnel ?
root@serre:~# cat /proc/mdstat
