tune2fs  -c 100 -i 90 /dev/sda8   # count: x-times, i: time-interval
( -c  Adjust the number of mounts after which the file system will be checked by  e2fsck(8).
-i  interval-between-checks[d|m|w]

  terval-between-checks as days, m as months, and w as weeks.  A value of zero will disable the  time-de‐
  pendent checking.
