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