[URGENT]plantage de mon raid 1 software

bonjour,

j'ai un gros soucis depuis quelque jour avec mon raid 1 "linux"

il ce bloque et le kernel remonte la partition en "ro" au lieu du bon vieux "rw"

j'ai regarder dans les logs tous ce qui concerne mon raid en locurence md0 et j'obtient toute les lignes suivante.

j'aporte comme précision que  mon raid est posséde 1 seul partition "logique" et  elle est formaté en ext3.

dmesg:[17179594.964000] md: md0 stopped.
dmesg:[17179594.964000] raid1: raid set md0 active with 2 out of 2 mirrors
dmesg:[17179612.484000] EXT2-fs: md0: couldn't mount because of unsupported optional features (4).
