Em man tune2fs
-c max-mount-countsAdjust the number of mounts after which the filesystem will be checked by
e2fsck(8). If max-mount-counts is0or-1, the number of times the filesystem is mounted will be disregarded bye2fsck(8)and the kernel.
Nesse caso, "desconsiderado" significa que sim, fsck nunca será executado por esse motivo e isso é normal. No entanto, há também
-i interval-between-checks[d|m|w]Adjust the maximal time between two filesystem checks. No suffix or
dwill interpret the number interval-between-checks as days,mas months, andwas weeks. A value of zero will disable the time-dependent checking.
Portanto, fsck ainda pode ser executado por outro motivo, dependendo de o intervalo estar ou não definido.
It is strongly recommended that either
-c(mount-count-dependent) or-i(time-dependent) checking be enabled to force periodic fulle2fsck(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.
