    Désactivation du cache d'écriture des disques apparemment et délai de commit pour le système de fichiers à 600 sec si je comprends bien (ou pas?) et remontage des disques.

    -> sdb1 et sdb2 sont mes partitions système et home sur un ssd hors du raid.
    Même punition : commit à 600 ?

    Retour du cache en écriture et du commit EXT4-fs à 0.

    Je n'y comprends pas grand chose... toutes les veilles coté DM (plasma5) sont sur off normalement.
    Je suppose que je paye le fait d'être en cauldron :)
