config.vm.synced_folder Always mounts as vagrant

[carcus88]

I have not been able to find any combination of mounting options that will allow me to mount a synced folder as anything but vagrant

I have tried
:owner => 'www-data', :group => 'www-data'
And
owner: 'www-data', group: 'www-data'

But no matter what every time i do a
vagrant reload

The mounts are always vagrant. From the code in this provider it looks like it should be obeying the option but never seems to. This is happening with Vagrant 1.4.1
and Parallels 9

Does anyone else have the same issue or know of a work-around?

Thanks for a response, I've investigated the Shared Folder mounting in Parallels-based Linux machines.

I have not been able to find any combination of mounting options that will allow me to mount a synced folder as anything but vagrant

Currently we are using a ParallelsTools approach to mount shared folders. Our provider only creates a symlink to the appropriate mount point /media/psf/<share_name>.
(see ..lib/vagrant-parallels/guest_cap/linux/mount_parallels_shared_folder.rb)
That's why the provider ignores any mount options and uid/gid as well. It is not "Vagrant-way" and I should fix it and make shared folders mounting more advanced, like as VirtualBox provider do it.

But...

The mounts are always vagrant.

It's not quite right. Parallels Tools daemon is mounting shared folders using the next default options:

$ mount
...
vagrant on /media/psf/vagrant type prl_fs (rw,nosuid,nodev,sync,noatime,share)

See "man mount" to get more info about these options. Since nosuid is set, every system user is seeing such mount point as his own:

[vagrant@host ~]$ ls -l /media/psf/
drwxr-xr-x 1 vagrant vagrant  748 Mar 17 23:10 vagrant

[vagrant@host ~]$ sudo ls -l /media/psf/
drwxr-xr-x 1 root root  748 Mar 17 23:10 vagrant

[vagrant@host ~]$ sudo -u puppet ls -l /media/psf/
drwxr-xr-x 1 puppet puppet  748 Mar 17 23:10 vagrant

So, you should not have any problems with access to these folders, right?

[carcus88]

Right I don't have any problems accessing the files and now it makes sense why I saw some mounts as vagrant and some as root because now that I go back and

sudo ls /my/mount/point

I see it as root or whoever I'm sudoing as.

This also explains why my app seems to have the correct permissions in Apache because it runs as www-data and sees the mounted files as www-data. I was confused why things worked when it seemed like they should not given the fact they appeared to be owned as vagrant. I'm also concerned that others may chase this too only to find out the same thing.

Is the proper thing to do here mount it as the user/group specified and use the nosuid option if nothing was asked for, or is this not a bug because of the use of nosuid?

Fixed in v1.0.3

Now, in Linux guests shared folders are mounted directly to the specified path instead using a symlinks. It is possible to use mount options

Sorry to highjack this but I have been trying for months to mount shared folder as non-root and failed. I have a thread on https://forum.parallels.com/threads/how-to-mount-psf-shared-home-folder-as-a-non-root-user.338151/ and opened two tickets with Parallels support. They were not able to provide anything useful so far.

@ssbarnea, seems share mount option in prl_fs is what you need.

[ssbarnea]

@romankulikov Thanks! I was able to solve the problem using this approach:
cat /etc/mtab and copy the line from there to /etc/fstab and adding uid=xxx,gid=xxx. Doing a mount -a and I am done.
