euh j'aurais plutôt dis l'option -i nan?
-i interval-between-checks[d|m|w]
Adjust the maximal time between two filesystem checks. No suffix or d will interpret the number interval-between-checks as days, m
as months, and w as weeks. A value of zero will disable the time-dependent checking.
It is strongly recommended that either -c (mount-count-dependent) or -i (time-dependent) checking be enabled to force periodic full
e2fsck(8) checking of the filesystem. Failure to do so may lead to filesystem corruption (due to bad disks, cables, memory, or
kernel bugs) going unnoticed, ultimately resulting in data loss or corruption.
