linux - Crontab running before nfs mounted

Running Cronjob @reboot returns that file on nfs share does not exist.

Example

@reboot python /abs/path/to/script.py

mail from crontab on startup reads "more or less"

/usr/bin/python can't open file "/abs/path/to/script.py": [Error No. 2] No such file or folder.

Script can be run from the command line with no trouble..
Theory is that the cronjob is running before mount has been run.
The questions.

1. Is this theory correct?


2. Is there a way to force the job to wail until the drive has been mounted? .... Other than just putting in a sleep 60 into the command. ;) I tried that already, but it's hit and miss and I need the script to run 100% of the time quickly.

Answer

You can use the mountpoint command to ensure the mount has taken place before you execute your command e.g. (assuming /abs is the mount point)

#!/bin/bash
while true
do

    if mountpoint -q /abs
        then
            /usr/bin/python /abs/path/to/script.py
            break
        fi
    sleep 10
done
