I am running OS X Lion. I have the following line in my /etc/fstab:

//darren:q@acid/home /acid smbfs nodev,nosuid,auto

If I run mount -a, the share mounts correctly, but if I just reboot the computer, the drive does not mount.

The drive in question is an Ubuntu SMB share.

Can anyone advise?

I ran across this today which is one way to do it.

In summary for Mountain Lion:

  1. Edit the file /etc/auto_master
  2. Within add /- auto_smb
  3. Create /etc/auto_smb
  4. Within add /Volumes/mount_point -fstype=smbfs,soft ://user:pass@smbserver/share

The author goes onto mention a second method using the vifs command, but I've never tried that one and it seems to do something of a pre-mount at bootup. You still have to touch the Volume for it to completely mount.

Lastly, the author states that "soft" should be used in step 4 above because failures to mount will cause the bootup to hang.

  • Thanks for the answer. Would you mind summarizing the instructions provided in the link? It is often good to include a link with your answer, however, links can break over time, so it best that they are not solely the answer. Jan 3, 2013 at 22:32
  • will mount -a work if for some reason it didnt mounted on startup ? Mar 6, 2018 at 14:26

You need to mount the drive once, then go to Settings Panel and Users & Groups. There you can add it. If you hide it, it will mount but don't open the finder screen upon logging in.

  • It does. Screenshot only show the screen where you should do it, not the program. May 2, 2013 at 18:23
  • OK. How then do you automount an SMB drive via Settings > Users & Groups > Login Items I've done it via the accepted answer (/etc/auto_master and /etc/auto_smb), but I don't know what program you would put into Settings > Users & Groups > Login Items to make it work. A bash script of your own devising? If so, what would the script say?

  • Just use Finder to mount it, then you can add it to the screen above. Jun 15, 2013 at 20:59
  • oh, now I see what you mean (when you just said "then you can add it" it wasn't clear you meant "drag the mounted volume onto the Login Items list"). I didn't know that volumes could be added to that list ... but, clearly, they can. That's a great tip, thanks!
