I have a few NFS mounts that I want to be working at all times. If there is a power outage, sometimes NFS clients come up before the NFS server does, and thus the mounts are not there. I wrote a quick little bash script to fix this utilizing the mountpoint command.

Behold (Change the mountpoint(s) to the one you want to monitor.)

#!/bin/bash
#Simple bash script to check mount points and re-mount them if they're not mounted
#Authored by Nick Jepspon 8/11/2019

### Variables ###
# Changes these to suit your needs

MOUNTPOINTS=(/mnt/1 /mnt/2 /mnt/3)  #space separated list of mountpoints to monitor

### End Variables ###


for mount in $MOUNTPOINTS 
do
    if  ! mountpoint -q $mount
    then
        echo "$mount is not mounted, attempting to mount."
        mount $mount
    fi
    #otherwise do nothing
done

I have this set as a cronjob running every 5 minutes

*/5 * * * * /mountcheck.sh

Now the system will continually try to mount the specified folder if it isn’t already mounted.
