| 3 | # e2croncheck -- run e2fsck automatically out of /etc/cron.weekly |
| 4 | # |
| 5 | # This script is intended to be run by the system administrator |
| 6 | # periodically from the command line, or to be run once a week |
| 7 | # or so by the cron daemon to check a mounted filesystem (normally |
| 8 | # the root filesystem, but it could be used to check other filesystems |
| 9 | # that are always mounted when the system is booted). |
| 10 | # |
| 11 | # Make sure you customize "VG" so it is your LVM volume group name, |
| 12 | # "VOLUME" so it is the name of the filesystem's logical volume, |
| 13 | # and "EMAIL" to be your e-mail address |
