# 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
