Can't see the file list in guest

[mfilipe]

I'm trying to communicate a Windows 10 (host) and a FreeBSD 10.2 (guest).

When I boot the guest, it mounts the host dir, but I can't see the file list ($ ls /vagrant) into the dir. If I try to open a file using some editor, it opens the file content even the file is not listed.

I'm experiencing the same with a FreeBSD 10.1 guest, this is what I see in the client:

root@devserver:/usr/local/www/perceptyx # ls -lah
total 0

And this is what I see in the winnfsd side:

[17:42:47] NFS ACCESS \\?\c:\code\Perceptyx  OK
[17:42:47] NFS FSSTAT \\?\c:\code\Perceptyx  OK
[17:42:47] NFS READDIR \\?\c:\code\Perceptyx  OK
[17:42:47] NFS FSSTAT \\?\c:\code\Perceptyx  OK
[17:42:47] NFS READDIR \\?\c:\code\Perceptyx  OK

However a lot of files exists in C:\code\Perceptyx. I even tried @marcharding latest build:

I'm trying to get this working but not sure how to get more debug in order to fix this.

Thanks!

Adding more info, this is only affects FreeBSD guests. Below is a screenshot of the FreeBSD guest creating a file and all files are visible in Ubuntu guest but not in FreeBSD guest.

I will try to compare mount options and if possible a network packet capture to see if I can catch the difference.

Thanks!

Ok I found the issue, FreeBSD does not mount NFS with the following option:

 rdirplus
     Used with NFSV3 to specify that the ReaddirPlus RPC
     should be used.  For NFSV4, setting this option has a
     similar effect, in that it will make the Readdir Opera-
     tion get more attributes.  This option reduces RPC traf-
     fic for cases such as ``ls -l'', but tends to flood the
     attribute and name caches with prefetched entries.  Try
     this option and see whether performance improves or
     degrades.  Probably most useful for client to server net-
     work interconnects with a large bandwidth times delay
     product.

Using this option this options the files are shown when you run ls -l, for example:

mount -t nfs -o nfsv3 -o udp -o nolockd -o rdirplus IP:/share /mnt

Unfortunately Vagrant has a bug (mitchellh/vagrant#7466) and this options can't be used in Vagrantfile like below until is fixed.

config.vm.synced_folder "C:\code\Perceptyx", "/usr/local/www/perceptyx",
:nfs => true,
:nfs_udp => true,
:nfs_version => 3,
:mount_options => ['nfsv3,udp,nolockd,rdirplus,actimeo=2,async']

Hope this helps someone and I think it worth adding this note to Readme / @marcharding @GM-Alex

Thanks!

Hey @amontalban,

thanks for the thorough issue.

I think i fixed the issue (READDIR was not implemented correctly).

Please try the attached exe and report your results ;)

WinNFSd.zip

Hey @marcharding,

Worked like a charm!

Just one thing, I had to execute the following command:

winnfsd.exe -log on C:\code\Perceptyx /C/code/Perceptyx

Because if I didn't specify the /C/code/Perceptyx argument the share was created as C:\code\Perceptyx and don't know how to mount that.

Before I didn't have to do this, so maybe it worth checking if it works good in vagrant-winnfsd.

PS: When you think this version will be released so I can install the plugin with this exe?

Thank you for the quick fix!

This behaviour (wrong mount alias) is also fixed now, i'll release a new version sometime this week.

Fixed with v1.2.0
