Can not mount nfs shares

I have a centos server which tries to mount a nfs share from an osx server tiger.
on the osx server showmount -e shows me the mountpoint perfectly.
on the linux server i try to mount the mountpoint and after some time it gives me the error:
mount.nfs: Input/output error
does this sound familiar to anyone? please help me :P

more information:
nidump -r /exports .
"name" = ( "exports" );
CHILDREN = (
"clients" = ( "192.168.0.10" );
"name" = ( "/backup" );
"opts" = ( "" );
showmount -a returns:
Exports list on localhost:
/backup 192.168.0.10

[SOLVED]Can´t mount nfs shares!

Hello,
I am trying to get up a fileserver. I installed an old PC with Arch and configerd it over SSH. I followed the wiki over NFS and NFSv4. But everytime I want to mount a share that is in the physical map /home/jozef/shares/downloads, I get the following error:
mount.nfs4: timeout set for Mon Aug 24 14:36:57 2009
mount.nfs4: text-based options: 'clientaddr=192.168.0.100,addr=192.168.0.111'
mount.nfs4: mount(2): Permission denied mount.nfs4: access denied by server while mounting 192.168.0.111:/shares/downloads
I tried to mount it with the following command:
mount -v -t nfs4 192.168.0.111:/shares/downloads /media/Downloads-Server
Lets call the fileserver fileserver and my workstation Gamepc. Here I will give you some files that I think are needed, from fileserver and Gamepc are there other files you need, I will post them.

Are you sure that the nfs module is loaded? Do
lsmod | grep nfs
to check. If "nfs" doesn't appear then that's your problem. Do:
sudo modprobe nfs
and continue.
EDIT: Also, I'll assume both your server and your client machine are connected to the network. You have the network DAEMON "!"-disabled in each machine's /etc/rc.conf. So I'm assuming you're connecting them to the network in some other way, and have verified that you can, for example, ssh from one machine to the other.
Third, you're sure that /share exists on your server machine, that a (presumably empty) directory /share/downloads exists inside it, that another folder is mounted on top of that empty directory? When you type "mount" on the server machine there should be a line containing "on /share/downloads".
Fourth, if your client's ip address is 192.168.0.100 (this will be displayed when you do "ifconfig") then the /etc/exports on your server has been changed to read:
/shares 192.168.0.100(rw,fsid=0,no_subtree_check,async,no_root_squash)
/shares/downloads 192.168.0.100(rw,no_subtree_check,async,no_root_squash,nohide)
Then you either typed "exportfs -rf" on the server, or stopped and restarted nfs-server. (I'd stop nfs-server, nfs-common, and rpcbind, then start them up again in reverse order, to be sure.)
STATD_OPTS has no effect in /etc/conf.d/nfs-server. Also, you don't need to use statd if you're using nfs4. So you could change /etc/conf.d/nfs-common to read:
NEED_STATD=no
NEED_IDMAPD=yes
and /etc/conf.d/server and can be blank.
(Then restart everything, as described above.)
If you're using the latest arch packages then portmap has been replaced by rpcbind (which you do have in your DAEMONS line on the server). So you need to change the "portmap:" line in your server's /etc/hosts.allow to "rpcbind:". I also have a "lockd:" line in my /etc/hosts.allow, in addition to what you have. It's probably not the source of your present troubles, and I'm not sure it's necessary. But you could try adding it.
Finally, did you add/change a "Domain = ..." line in the /etc/idmapd.conf on your server, and a corrsponding line in the /etc/idmapd.conf on your client?

Can't mount NFS share via GUI

Mac OS X 10.8.2
MacBookPro5,3
Hello,
I've recently upgraded to OS X 10.8.2 and am having great difficulty in mounting my NFS shares via the OSX GUI. This worked fine at OS X 10.6.
My aim is to provide an automount type of setup so that less experienced users don't have to worry about the command line.
Can someone please point me in the right direction here?
This is what I've tried to date.
My NFS service is hosted on my Debian server. It supports NFS v4. The service is working and stable and is used routinely with Ubuntu clients. It has also worked with OS X 10.6 clients in the past, but not with OS X 10.7 clients.
To date I have tried the following options:
Mount via finder: Connect to server option using syntax: nfs://<user>@<server>/<share>
setting up autofs using the instructions from pmbuko
using the command line to mount the share.
The first option failed repeatedly. I did find that it would eventually work, though only after I'd manually mounted the share at the command line.
I have not been able to get the second option to work.
I initiate autofs using the command 'automount -vc' and see that the connection is recognised
when I attempt to cd into a directory below the mount point, I eventually get the message 'Connection Refused'.
when I check my Debian logs, I find that the NFS service had actually received an authenticated mount request from the Mac.
when I check my Mac Console logs, I see an error:kernel: nfs_connect: socket error 61 for <server>/<share>
I was able to get the third option working, but only after using the '-o resvport' option.
'Something' does appear to be broken with OS X 10.8.2 as an NFS client.
Any thoughts?

I have found a work around that meets my imediate needs, though it doesn't allow me to use autofs functionality.
The work around uses the traditional Unix/Linux approach of automatically mounting a file system or NFS share via fstab at boot time. OS X 10.8 still supports fstab, even though the file is not included in the default installation.
Once mounted, the NFS share appears as if it is part of the normal file system.
The following is only intended for people confident in Unix or Linux systems administration and in using a shell environment via the command line. Do not attempt this if you do not have these skills.
To set up for fstab, do the following within a terminal session:
create an empty directory in your file system that you can use as your mount point for your NFS share:
sudo mkdir /data/share
sudo chown root:wheel /data/share
using your favourite editor, create the fstab file (in a terminal type 'man fstab' for details)
sudo vi /etc/fstab
add similar to the following to /etc/fstab and then save and exit, substituting your own values where appropriate
# My NFS share
<your-server>:/<your-share> /data/share nfs resvport,rw,hard,intr 0 0
sudo chown root:wheel /etc/fstab
Please note: you may not need the resvport option in the fstab line above. It will depend on your NFS server's requirements.
Once you have done this, reboot your Mac and your NFS share should be mounted at the mount point that you defined.
If not, check your logs to see what went wrong.

Can not mount smb share on osx 10.4.6

I have a linux suse 10 machine and I would like to mount files that are on my osx 10.4.6 machine. The KDE gui to do this does not work at all so I went to the command line and it turns out that os x is not asking for the password until after the timeout. From the command line I can still get the job done but why is os x not asking for the password until after the timeout? Below is the relevant command sequence.In this case the password is no the command line, but it still waits for the timeout before connecting.
linux:/home/dave # smbclient //192.168.0.4/Dave -U Dave%mypassword
timeout connecting to 192.168.0.4:445
Domain=[GANDALF] OS=[Unix] Server=[Samba 3.0.10]
You can see the timeout message and then the successful connection. The same thing happens when I try to mount the smb file system.
Any thoughts? I think this is a bug

At home I am running Suse 9.3 and have no trouble connecting to my powerbook (10.4.6). I do use the KDE "explorer" program (Konqueror) and just type in (in the address bar):
smb://IPADDRESS/SHARENAME
It takes a few seconds but a windows pops up asking for user name and password. A few more seconds and I'm in.
Are both machines on a domain or a workgroup? I just have a 2 computer workgroup called "Home" (creative, I know). In the Yast control center in Suse I configured the Samba client to be blank in the "Membership" box. Maybe try changing that around (make it blank or if it is blank, enter the workgroup name).
If this doesn't help, you may want to try posting this question in a Linux forum, specifically Suse 10.0 if possible. There are definitely a lot of variations b/t distributions, even b/t different versions of the same distro.

Mounting nfs shares takes much longer since updating to 10.3.9

Hi, first post here. The titles of the forums are vague and I hope "getting online" really is the "networking forum"; apologies if not.
I have two linux machines which I regularly mount nfs shares from onto my powerbook. These machines are on the LAN and have known IP's for netinfod so I don't think the following problem is DNS related.
Since the last 10.3.9 update, mounting these shares (via finder or command line mount_nfs) has become very unreliable. Sometimes they never seem to mount, sometimes almost immediately, and other times they mount eventually even though I might of canceled the dialog box waiting for the mount. The logs show:
mount_nfs: bad MNT RPC: RPC: Timed out
The server side logs show only repeated authentication approvals. The servers have not changed software -- only OSX has been updated.
Independent if I use WiFi or a landline.
Once the shares are mounted, there is no detectable connection problems at all. Was any part of the NFS client updated in 10.3.9? Any ideas what might be wrong. TIA.
12" PowerBook G4 Mac OS X (10.3.9)

Just to bump this, as no one has chimed in, I found the problem and I will post the fix only if someone asks. It's not stupid, and it might help you. I am surprised that no one cares.
I'd still like to know why you can't launch PS from a bootable backup.

Cannot mount nfs shares

Hello,
since Sunday I'm unable to mount NFS shares:
mount.nfs: No such device
The server-side is working fine, I can mount all shares from my FreeBSD Desktop machine.
I'm using netcfg and start rpcbind and nfs-common upong connection before mounting NFS shares (via netfs). Is this maybe related to some recent pacman updates? It was working flawless just until Sunday.

As it turns out, It now works. I did load the nfs module manually during my troubleshooting but it was already loaded or built into the kernel or whatever.
The thing that made it work is changing the nfs mount lines in /etc/fstab from the hostname of the server to the ip address of the server. I don't know why that worked on both machines since I could ping the hostname of the nfs server which is a Freenas server and it always worked before.
@ jasonwryan
rc.d start rpcbind && rc.d start nfs-common
start fine after stopped and restarted. Have you replaced portmap with rpcbind in pacman? rpcbind superceded portmap a while back. gl.
@.:B:.
lol, snide remark succesfully detected. In my defense I was half guessing and half sniding (or some percentage thereof). I have to admit I do get a bit snippy over this since nfs is necessary for my little clients to run mpd and I gets a bit cranky when I gots no musics! Fueling my frustration, it seems I have to chase down nfs problems frequently after "pacman -Syu".

Hi,
This issue indicate corrupted database or corrupted logs. I suggest you to check and repair the database or check and repair the database log.
1. Check the state of database by following command: eseutil /mh "Path of the database"
Ps: Default path of the database is “C:\Program Files\Microsoft\Exchange Server\V15\Mailbox\Mailbox Database\Mailbox Database.edb”
Default path of the log files is “C:\Program Files\Microsoft\Exchange Server\V15\Mailbox\Mailbox Database\E00”
2. If the state is in clean shutdown, move all the log files from the Transaction logs folder location and then mount the database.
3. If the state is in dirty shutdown, check if the log files that is indicated as Logs required is available or not.
4. You can run Eseutil ml “Path of the log file\e00” to make sure that the log files is required is in a Clean state. This command will help you check the health of all the log files in the location.
5. If the log files are healthy, then try Soft recovery with the command Eseutil /r e00 /l ”Path of log files” /p “Path of the database”
Note:
Make sure you make a backup of the database before attempting any kind of repairs
6. Once the command completes successfully, then mount the database.
7. In case the required log files are not available in a clean state or missing, either restore from a successful back up or perform Hard repair with defragment.
Refer to this file about hard repair:

Hope this will be helpful for you

Reinstall MacFuse with the one from http://www.tuxera.com/mac/macfuse-core-10.5-2.1.9.dmg. If that doesn't work, you can use Paragon NTFS for Mac 9.0 which has been designed to work with Lion.

"mount: only root can mount" or "Unprivileged user can not mount NTFS"

I'm trying to set up an NTFS partition to use as a common data partition between Arch and Windows. I have it added to fstab so that any user in the ntfsuser group can have access to it, but if it gets unmounted accidentally from the "eject" symbol in the nautilus gui, you have to sudo to mount it back up. Is there a way for it to be remounted automatically when you click on the partition again in Nautilus? I've searched all through the forums and looked through several articles on the wiki but haven't been able to come up with anything. The error I get says
mount: only root can mount /dev/sda4 on /home/adam/UserData
I've tried adding the users option to fstab, but that only manages to change the error to
Unprivileged user can not mount NTFS block devices using the external FUSE
library. Either mount the volume as root, or rebuild NTFS-3G with integrated
FUSE support and make it setuid root. Please see more information at
http://ntfs-3g.org/support.html#unprivileged
I've tried the suggestions at the link in the error, as well as tried the solutions given in [solved] Gnome : mounting NTFS partition as user and a few other posts, but still nothing. If possible, I'd prefer to stay away from the users option in fstab, since it adds a redundant link to the sidebar in nautilus with a different name.

@Mr.Elendig: It is mounted through fstab normally, but in nautilus there's an eject icon on the sidebar next to the name of the drive which I've accidentally clicked on a couple times if I'm just trying to open the drive real quick. Once its been unmounted like that it won't let me remount unless I use sudo. I'm just looking for something to make it a little more convenient than having to pop open a cli and type in a password.
I'll try the suid root when I get home tonight, otherwise I'll look into autofs.

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

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

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!

Can't create or mount NFS share

I am trying to create an NFS share on a server that already does quite nicely sharing AFP and SMB. A friend tells me that this is easy but I can't make it work, I'm still told that my password is incorrect.
Can you watch this short movie to see what I'm doing and advise what I'm doing wrong?
Thank you in advance.

Can't mount NFS from my Arch laptop, am I missing something obvious?

Hello,
I have been trying to solve this issue for over a week and tried everything that I can imagine with no luck...
Set up:
- Qnap SS-839 Pro with several NFS shares on
/share/to_sort
/share/movies
/share/music
etc.
- MythTV frontend/backend running Mythbuntu.
I can mount my NFS shares without problem. I use this fstab.
192.168.1.100:/share/Music /var/lib/mythtv/music nfs nolock,async,proto=tcp,rw,ac 0 0
192.168.1.100:/share/Videos /var/lib/mythtv/videos nfs nolock,async,proto=tcp,rw,ac 0 0
- Arch laptop
I can't get to mount any of the NFS share:
[18:59:14][[email protected]]
/mnt/aether Arch64# /etc/rc.d/rpcbind restart
:: Stopping rpcbind [DONE]
:: Starting rpcbind [DONE]
[18:59:32][[email protected]]
/mnt/aether Arch64# mount 192.168.1.100:/share/to_sort/ to_sort/
mount.nfs: rpc.statd is not running but is required for remote locking.
mount.nfs: Either use '-o nolock' to keep locks local, or start statd.
mount.nfs: an incorrect mount option was specified
[19:00:03][[email protected]]
/mnt/aether Arch64# mount 192.168.1.100:/share/to_sort/ to_sort/ -o no-lock
mount.nfs: an incorrect mount option was specified
I tried using the 2 following lines in my fstab on my laptop but nothing works:
1) 192.168.1.100:/share/to_sort /mnt/aether/to_sort nfs nolock,async,proto=tcp,rw,ac 0 0 (same option than under mythbuntu)
2) 192.168.1.100:/share/to_sort /mnt/aether/to_sort nfs defaults 0 0
I'm no guru when it comes to nfs sharing etc, but I really can't see what I am missing here, nor whatelse can I try!
Any idea will be more than welcome!
Thanks in advance

I finally solved this problem after 4 months after someone posted a similar issue with Arch few days ago...
He said to install the iana-etc package... I already had the package but still gave it a go:
[08:15:33][[email protected]]
~ Arch64$ showmount -e 192.168.0.100
clnt_create: RPC: Unknown host
[08:15:41][[email protected]]
~ Arch64$ sudo pacman -Syu iana-etc

As you can see, it is now working and I am now completely puzzled...
How come reinstalling this package solved the issue?
Any idea on what the problem was would be more than welcome
Thanks

Can't mount NFS exports on Arch laptop

I've browsed the forums, double checked the wiki, but for some reason I'm not able to mount my NFS exports. There must be some small issue not letting me do this, but I can't find it. This is my /etc/exports file on the server (desktop):
/glados 192.168.0.99(rw,fsid=0,no_subtree_check)
/glados/movies 192.168.0.99(rw,no_subtree_check)
And the order of the rc.conf daemons on the server:
DAEMONS=(syslog-ng dbus network @netfs crond rpcbind nfs-common nfs-server !hwclock ntpd)
On the client (laptop):
DAEMONS=(syslog-ng dbus network crond @bumblebeed @networkmanager @postgresql rpcbind nfs-common nfs-server sshd)
$ showmount -e 192.168.1.101
Export list for 192.168.1.101:
/glados/movies 192.168.0.99
/glados 192.168.0.99
Now try mount:
$ sudo mount -t nfs4 192.168.1.101:/movies server/
Here it just freezes and nothing happens. I also did the configuration both on server and client side of /etc/idmapd.conf, adding a domain.
Nothing happens on the client side when I try to mount. It just freezes there. Both machines running up to date ArchLinux.
Any help is appreciated!

I just thought that server/ was a typo
He's able to use showmount -e 192.168.1.101 from the machine with the ip 192.168.0.99 so assumed his network's functioning ok ... but you know what they say about 'assume', which machine did you actually run the showmount command on? This might be stating the obvious, but if you ran it on 192.168.0.101 make sure 192.168.0.99 and 192.168.1.101 are communicating with each other
Also I think you're not mounting the path correctly, you have movies exported as:
/glados/movies 192.168.0.99(rw,no_subtree_check)
But you're trying to mount it as:
sudo mount -t nfs4 192.168.1.101:/movies server/
Try mounting it something like this:
sudo mount -t nfs4 192.168.1.101:/glados/movies /server/movies
That command is assuming you're wanting to put your nfs shares inside a folder called /server, also be aware that the directory you're trying to mount your shares inside of has to already exist
Incidentally, why are you mounting /glados and then also mounting directories unger /glados such as /glados/movies, by mounting /glados as an nfs share you already have access to /glados/movies. Once /glados is mounted then you can symlink to or bind mount any directories under it to any location you want
