Error mounting NFS share - mount.nfs: Operation not permitted

loafer · 2010-03-03 22:00:31

I've got an NFS share on a FreeBSD server which I mount via fstab.

It mounts automatically at boot and everything is fine.

However, if I unmount it and try to mount it again I get:

mount.nfs: Operation not permitted

I have tried vers=3 and nfsvers=3 in fstab, but to no avail.

rpcbind is allowed in /etc/hosts.allow.

Does anyone have any ideas?

fstab entry:

server:/path/to/files /mnt/files nfs ro,hard,intr,nfsvers=3 0 0

What error are you getting exactly? It looks like you are trying to mount it not as root.

This is the output of mount.nfs -v as root. As I say it mounts automatically at boot up.

Let me have a look at my FreeBSD NFS config when I get home.

Just in case I wasn't clear. The share is on FreeBSD and I am mounting it on Arch. So, the errors at at the Arch end.

Ok well since you obviously have the entry in fstab, what happens if you {re}start the netfs daemon?
Whenever I have to manually mount NFS I use the netfs daemon rather than using the mount command directly.

loafer · 2010-03-04 10:36:01

It's really strange as restarting the daemon produces exactly the same error. But when the daemon starts at boot it mounts the remote share. I'm lost. Port 2049 is allowed on the client firewall and iptables.log doesn't show anything being blocked.

Tagging along, I have the same problem, although I have a different setup:
- Server = Arch linux
- Client1 = Debian Testing linux
- Client2 = Arch linux

On client1, I'm unable to mount all NFS-shares. 2 out of 3 mount ok and the third fails with this error (both through fstab and manually):
# mount -a
mount.nfs4: access denied by server while mounting (null)

On Client2 I'm able to connect automatically and manually to all shares.

Maybe it is Debian-related, but the debian user forums have not been of much help...

THX for any input!
