Is it possible to share a NTFS partition using NFS?

Jongi · 08-31-2008, 10:54 AM

I've setup ext3 and reiserfs partitions without a problem. However NTFS gives the following error when i try to export fromthe NFS server

Code:

[root:~#] /usr/sbin/exportfs -rv
exporting 10.0.0.1/255.255.255.0:/nfs4exports/share1
exportfs: Warning: /nfs4exports/share1 does not support NFS export.

Is the NFS server dual booting? Why ntfs?

Could you try nfs 3 to share that filesystem instead. Or don't use NTFS.

I wonder if ironically this problem is due to NFS4 adapting Window's ACLs and a stateful model. They based their ACLs on the specifications that MS released under a court order. The main theme of the case against MS in Europe is interoperability. MS was ordered to release the networking specifications to enhance interopability between Unix and Windows. MS instead released phony specs which the NFS4 programming team used. So NFS4 uses Windows ACLs that don't work with windows. ( This is what torked off the EU judges )

yeah it's a dual boot unfortunately. it is a legacy of when I was still switching to windows a lot. It's a 150GB partition which I want to convert to a linux partition. But that's gonna be some time away.

I have no problems using nfs 3. How would I go about doing that?

Hi Jongi:

I have successfully exported ntfs partitions over nfs. Depends on how you mount and export them, plus NFS version.

Code:

~]$ cat /etc/sysconfig/nfs|grep -v \#
MOUNTD_NFS_V3="yes"
RQUOTAD="/usr/sbin/rpc.rquotad"
RQUOTAD_PORT=875
LOCKD_TCPPORT=32803
LOCKD_UDPPORT=32769
RPCNFSDCOUNT=4
MOUNTD_PORT=892
STATD_PORT=662
RPCMTAB="noload"
~]$

Code:

~]$ cat /etc/fstab
[...]
/dev/sda1       /mnt/c_drive    ntfs-3g rw,defaults,umask=022   0       0
[...]

Code:

~]$ cat /etc/exports

/mnt/c_drive/ 192.168.0.2(async,all_squash) \
         192.168.2.2(async,all_squash)
~]$

Good Luck,

Here's my relevant data from the NFS server:

Code:

[root:~#] cat /etc/sysconfig/nfs|grep -v \#
MOUNTD_NFS_V3="yes"

/etc/fstab

Code:

/dev/sdc5               /mnt/Media              ntfs-3g  defaults,users  0 0
/mnt/Media              /nfs4exports/share1     none    bind    0 0

/etc/exports

Code:

/nfs4exports/share1             192.168.1.101/255.255.255.0(rw,async,all_squash)

Hi Jongi:

I do not undestand what you are doing with the mounts in fstab, nor why. You have mounted the NTFS partition sdc5 at /mnt/Media, then specified /mnt/Media at /nfs4exports/share1 with some strange (to me) options. I don't understand this arrangement, nor why it would be needed. The filesystem type 'none' for /nfs4exports/share1 in particular looks wrong, and could well be the cause of the failed NFS export.

the bind command is like a symlink in terms of the fstab. so /mnt/Media is linked to /nfs4exports/share1. It was done following a tutorial and it works for non-ntfs shares. I'll try change /nfs4exports/share1 to /mnt/Media in /etc/exports to see if it changes anything.
