Re: NFS gluster mount on Windows

["Jarvis, Jeremy" <jeremy.jarvis@xxxxxxxxxxxxxxxxxxxxx>]

I think I’m seeing a separate issue. I can set up the mount fine but using an IIS application it seems to always fail, read and write. I’m debugging now to make sure I’m impersonating the correct user.

Since I had a similar post earlier, this is what I found to work:

 

On your Gluster system:

gluster volume set volumename storage.owner-gid 0 (0 on CentOS is the ID for root)

gluster volume set volumename nfs.volume-access read-write

gluster volume set volumename nfs.rpc-auth-allow x.x.x.x

On your Windows system:

Install NFS services for Windows

Start Registry Editor

Locate HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ClientForNFS \CurrentVersion\Default 

Create two DWORD values named AnonymousUid and AnonymousGid

Set these values to the UID and GID of the Unix user you would like this NFS client to masquerade as. i.e. root's Unix ID on CentOS 7 is 0

Run cmd

mount -o anon x.x.x.x:/volumename G:

After doing the steps listed above, I can read and write to the Gluster volume from a Windows system over NFS. The only strange thing I can't figure out is why Windows still shows a line through the mount point when a) its mounted and b) can be read and written to.

Hi Ben, Thanks for the quick reply. I'm using windows 2008 r2, it's deploying to AWS so we're not tied to the OS version if there are issues. The NFS version is 3. The mount seems fine for access through file explorer and apps run from command line, I only see the failure when it's an IIS application.

Hi Jeremy.  A couple things first, as of today gluster only supports NFS v3 so make sure you are using v3 and tcp mounts.  I haven't personally tested Windows NFS with gluster, which version of Windows are you using?  I would be happy to setup a test in our lab in hopes of helping get this working, I have seen issues with other OSs mounting gNFS that had to be resolved, maybe we are hitting something similar here.
