Scheduling a task in Open Media Vault

I need to run some scripts every night to move some files around in OMV. I want something that simple and easy to maintain and more or less stock standard.

There are probably many variations on how this could be done but this is how I chose to do it.

Before we start it is worth noting I have my RAID mounted by OMV at:

/media/f20b47a4-d207-40aa-a7e6-42ea82354455

1. Ensure you have enabled home directories for users. I created a shared folder called “/home” and  enable this in “Access Rights Management | Users | Settings”:

Users Settings
2. Create a user called “scheduledtasks” and make a member of the groups as all your other users. As a result this user should have a home directory along the lines of:

/media/f20b47a4-d207-40aa-a7e6-42ea82354455/home/scheduledtasks
3. Create a shared folder called “scheduled_jobs”, I would also add this as a windows/smb shared folder.
4. In this folder create a simple shell script:

#!/bin/sh
echo "Running script /scheduled_jobs/test.sh"
5. Create a scheduled task with a command of:

bash ~/../../scheduled_jobs/test.sh

Scheduled task
6. Once you have saved the task click on the “Run” button to show the dialog to “Execute cron job” – click on “Start”. It should return “Running script /scheduled_jobs/test.sh”, which is of course the echo command inside the script.

 

When I setup a real task I found that for the types of task I wanted to do, including mounting SMB shares I needed to run it as root. This meant that I needed to specify the full path to my RAID drive. Thus my scripts started like:

#!/bin/sh
#
# Script to archive appropriate folders
# to the Archive folder.

RAIDRoot="/media/f20b47a4-d207-40aa-a7e6-42ea82354455"

# Source function library.
if [ -x /etc/rc.d/init.d/functions ]; then
. /etc/rc.d/init.d/functions
fi

#
# Get the date in the format "Day of Week" and time
# This will mean that we will effectively keep a weeks backup
#
SHORTDATE=`date +%a`


#
# User config section
#
ArchiveFolder="${RAIDRoot}/backups/daily/essentials"
LogDir="${RAIDRoot}/backups/daily/logs"
LOGFILE="${LogDir}/backup_essentials.log"

#
# archive folder exists
#
echo "Creating Backup Directory..."
echo "Creating Backup Directory..." >> $LOGFILE
su - root -c  "rm -Rf ${ArchiveFolder}"
su - root -c  "mkdir -p -v  ${ArchiveFolder} "
