auto-mount shared folders using fstab

[manuli]

hello,

i have tried several ways to mount my shared folders. first i mounted manually. bit annoying, then i wrote a shellscript with the commands, put it to /usrs/bin and added the directory to the rc.local file. that didnt work (double-clicking it mounted the folders, but they haven't been mounted upon reboot; maybe because expecting root pwd?).
then i tried to mount on startup via fstab using "workspace /mnt/macworkspace vboxsf defaults 0 0". still the same problem - after reboot, they are not mounted.
i am using a osx 10.8.3. host system, ubuntu 12.04 as a guest. interesting also - when the guest machine is powered off and i inspect its shared folders, there is no option for "permanent", though it being appearant when opening the shared folder options while guest system is running.

does anyone have a tip here? would appreciate a lot!

thanx in advance

No need to make a script if you are mounting the drive in /etc/rc.local . Just put the mount statement there and it will run at login.
edit the /etc/rc.local file and add according to example below.

Code: Select all

# By default this script does nothing.

mount -t vboxsf -o rw,uid=1000,gid=1000 shared /mnt/shared

exit 0

uid & gid are your user uid & gid
shared = name you gave the share
/mnt/shared = the absolution path to the mount point

thanx for your quick response! it worked indeed, but only for the first sudo-command. the following two lines seem to be ignored (or ...?)... any idea here? is there a special line-break or line-ending-character to insert?

[Perryg]

but only for the first sudo-command

Can you explain this better? First you don't need to have sudo in the mount statement since this is being loaded at boot by the OS. Are you trying to mount more than one share?

sorry... of course no sudo.
yes, i am trying to mount three shared folders. My thought was to just simply write the three commands to the rc.local file according your description, which would be something like:

Code: Select all

mount -t vboxsf -o rw,uid=1000,gid=1000 share /home/manuli/Share
mount -t vboxsf -o rw,uid=1000,gid=1000 workspace /home/manuli/macworkspace
mount -t vboxsf -o rw,uid=1000,gid=1000 DA /home/manuli/diplarbeit

exit 0

after reboot it mounts share to Share, but the other two are not mounted...

[Perryg]

Did you create the mount points?

[manuli]

Did you create the mount points?

yes. the directories do exist.

[Perryg]

If the names are correct (case matters) and the mount points are in fact created and the shares still do not work then you need to see what the error messages are. Look in /var/log/syslog or dmesg and see what they say.

Note: what you posted as your solution to multiple mounts is correct.

had a look at the syslog file. the vbox related entries would be:

[Perryg]

That's fine but the error probably will not show as a VBox but a different error. search for vboxsf or error

[Perryg]

Do the other shares work if you manually mount them?

[manuli]

That's fine but the error probably will not show as a VBox but a different error. search for vboxsf or error

searching for "error" results in several of these:

Code: Select all

searching for "vboxsf" in several of those:

[manuli]

mounting manually throws a protocol error.

[Perryg]

This is almost always a share name issue (case does not match) or the mount point either does not exist of case is wrong.
Look closely.

[manuli]

you were right. there were some name issues... stared too long at the screen thus haven't seen it. now it works! thank you so much for your support!
