macos - OSX / Samba - How do I automatically remount / reconnect to drives that have been disconnected?

Is there a simple method to automatically reconnect a network drive that has been disconnected due to network failure or some other issue. I have a batch job setup that periodically copies files to a network drive, when the drive disconnects, I need to manually remount the drive.

Answer

Add some code to check for the mounts and to try and remount them if needed - here's some (snipped bits) from a Linux backup bash script (sorry, no OSX to hand at the moment) - it might give you some pointers and maybe someone will post an OSX equivalent too:

thishost='myhostname'  
#
mountpoint='/root/mybackup'
#
mountoptions='-o username=bkuplinux,domain=mydomain,password=mypassword'
#
sharename='//ssc4/linux'
#
emailtarget='myemail@address.com'

backupfolder=$mountpoint/$thishost

if [ $(mount | grep -c $mountpoint) != 1 ]; then
  echo "$mountpoint mount is not present - trying to mount..."
  mount -t cifs $sharename $mountpoint $mountoptions
  if [ $(mount | grep -c $mountpoint) != 1 ]; then
    echo "$mountpoint mount is still not present - quitting"

    if [ "$emailtarget" != "" ]; then
      echo "$mountpoint mount is not present on $thishost so backup cannot continue" | mail -s "$thishost backup problem" $emailtarget
    fi
    exit 1
  fi
