To configure Mac OS X to automatically mount a Drobo FS share whenever it is accessed:
Add the following line to /etc/auto_master:
/Volumes/Drobo auto_drobo
Then (as root) create the file /etc/auto_drobo and add your mounts to it, e.g.
Share1 -fstype=smbfs ://username1:password1@192.168.1.2/Share1 Share2 -fstype=smbfs ://username2:password2@192.168.1.2/Share2
Use the following command to start the automount:
/usr/sbin/automount -vc
Now whenever the volume is accessed it will be automatically mounted.
You might also want to change the default automount timeout setting which is in /etc/autofs.conf.

you can also add the shares to your login items. i just found out that this works too
Why is it that after the Drobo goes to sleep and then comes back on my mac will readdress it? Usually it will be /Volumes/Media…but then it will change to /Volumes/Media-1….There is no Media-1 folder on the Drobo at all.
I don’t set a sleep timeout on my Drobo FS, it’s on all the time. But if your Drobo’s sleeping is causing this issue then it’s probably because your Mac hasn’t unmounted the old volume.
To overcome this set your automount timeout to match that of the Drobo. That way automount will expire and unmount the volume at around the same time as the Drobo goes to sleep.
The default automount timeout is set to 60 minutes, but you can set the duration before an unused export or share is unmounted by editing the
/etc/autofs.conffile and changing theAUTOMOUNT_TIMEOUToption.where is /etc/autofs.conf located at?
The
autofs.conffile is in your/etcfolder on your Mac.Problem solved, so far so good. Thanks for the help. Now I need to get the location set back to /Volumes/Media, instead of /Volumes/Media-5…so I’m thinking I just reset all devices…?
Reboot a Unix machine? That’s sacrilege!
This should do the job:
sudo automount -vcor
sudo killall -HUP automountMy DroboFS is always mounted when I check from the Terminal andn works just fine. But, when I click on it in the Finder window it alway has to connect. If I click on Shared / DroboFS and it connects, then I click on a directory outside of DroboFS and immediately click back on DroboFS, it has to connect again. WTF? Why can’t this mother stay connected in the Finder window?
I know this is an old post but I am trying to use it to mount my drobo 5n. But when i go to /Volumes/Drobo/Public it doesn’t work it says “-bash: cd: /Volumes/Drobo/Public/: No locks available”
Ive tried many variations on the auto_drobo file like:
Public -fstype=smbfs ://cruncher1:cruncer1@192.168.1.68/Public
Public -fstype=smbfs ://cruncher1:cruncer1@192.168.1.68/
Public -fstype=smbfs ://anonymous@192.168.1.68/Public
Public -fstype=smbfs ://anonymous@192.168.1.68/
Public -fstype=smbfs ://192.168.1.68/Public
Public -fstype=smbfs ://192.168.1.68/
I get the ‘No locks available’ message if the authentication credentials don’t match.
I suggest you check the username and password that you are specifying.
I’ve been trying this method for a Drobo 5N share on Yosemite, and am getting a “mountpoint unavailable” error upon execution of “/usr/sbin/automount -vc”. Any ideas?
Thanks so much.
It sounds like there may be a problem with your configuration file. What is the output from the ‘df’ command when the Drobo share is mounted?
