Ubuntu Networking :: NFS Mounts Cause A Hang On Reboot Of The Mounts Are Lost

Nov 24, 2010

I have multiple ubuntu machines and I connect to one through an NFS share. I have done this for a few years without issue. However, since re-installing ubuntu and upgrading to 10.4 I have a problem with my system hanging when the remote shares are lost.

Basically, I can power down the machine downstairs, and my main machine then has a fit. I can not open any folders in ubuntu, nor can I shut down. If I try and shut down the system hangs, last time it hung for 8 hours before I had to kill the power.

These are the lines in my fstab

I don't know what I've done wrong, or how I can prevent this from hanging. I have googled the heck out of this as well and can't seem to find an answer either.

CentOS 5 Networking :: CIFS Mounts Hang When Pushing Data / Resolve This?

Apr 9, 2009

Ive seen this a hundred times while searching google but I can't seem to get any of the fixes suggested to work for me.

Here are the specs code...

I have other servers on the same network with the same software/hardware that never loses its mount to the windows share, and nightly backups are run through those mounts. So why does the mount on this machine fail when we do a push? The only conclusion that I can come to is there is some sort of time out on the windows server that causes this. The other servers that have this same type mount use their share every night, where as the share on this server gets used once or twice a week. Once the mount hangs I can not unmount it, I have to reboot the server. Once the server is rebooted the push works fine. But then the next week when a push is tried it hangs. What else can I check?

UPDATE: I've also tried NFS mounts and autofs mounts and they hang as well

I enabled logging by echo 1 > cifsFYI and this is what I see in var/log/message code...

Ive removed the actual file names for security concerns. Any one have ideas as to why this is happening? The only other thing I can think of to try is to swap out the NIC but it's at a remote location so I can't do that right now.

Ubuntu Networking :: NFS Randomly Mounts On Boot

Jul 10, 2010

Here is my entry in the fstab: media/Our40NAS nfs auto,_ne
tdev,rw,hard,users,intr 0 0

Upon reboot, sometimes it would mount automatically and sometimes it would not. I have not discovered any specific pattern. It is very random. Sometimes it would go many reboots without mounting and on the next it would mount it. I tried putting timeo paramter, played with the parameters, but still have the same issue. My laptop is connected to a wireless network. When I do mount -a or if I go to Places everything mounts great. It just simply will not mount all the time automatically upon boot, and after wireless connection is established.

Fedora Networking :: 13 - NFS Mounts Fail ?

Jun 13, 2010

I have upgraded three machines to Fedora 13.

On all of them any attempt to mount an nfs drive fails with:


This happens immediately - within a few tenths of a second at most. It happens whether I use mount -a(mounts are listed in the fstab file) or a full mount command. It happens on both 32-bit and 64-bit installs.

Nothing appears in the messages log file on either the server or the client machine.

It was working in Fedora 12.

Iptables and ip6tables are both disabled. nfsd is running.

Hosts.allow and hosts.deny both exist on the client, but are empty. They contain nothing but comment lines.

I can ping the server and run ssh shells to it. I can open Web pages in Firefox.

The server is CentOS 5.4.

Networking :: Specifying The Source Address For SMB Mounts

Jan 11, 2010

Is there way that you can specify the source address to use when mounting a remote share? I'm trying to test an application, and I need to be able to script a job that connects to a remote SMB server using different local IP addresses on the system. It would have 1 main address, and several aliases in the same subnet. The script would mount the remote server, transfer a file, then unmount, change IP, and repeat.

Networking :: Where Does CIFS Log Failed Mounts

Jun 22, 2011

I`m using cifs to mount a windows 2008 server share. I`m mounting it read only and using an rsync script which works quiet nice.

Recently I couldnt mount the windows share anymore, i didnt know the account iam using would go inactive if i never logged in.

Just where does cifs write a log if it can`t mount a windows share? If I knew where it is it would also be easier to find the reason if it doesn`t work.

Ubuntu Networking :: Cifs Share Mounts But Cannot See Files?

Mar 10, 2010

I have a Buffalo Drivestation (model HD-CELU2, 1tb) attached to my network.From my ubuntu desktop I can go to the menu, select "connect to server", put in the ip and share info, and it mounts perfectly.I can open the share and browse eadwrite, but when I try to mount it from a terminal or within fstab, it will still mount, but I cannot see any files that are on the drive. I have about 12gb of data on it, but like I said when I mount it using "mount -t cifs 192.x.x.x/share blah blah blah" I do not see any of the files.If I do a df I can see that the drive has files on it based on the free space available, but if I do an ls nothing shows.

Ubuntu Networking :: NFS Mounts As Read-only File System

Dec 15, 2010

I am trying ti set up a NFS server using the guide on [URL] However, the NFS mounts on the client side as a read-only file system, so I cannot modify nothing. Here is my /etc/export file on the server side:

/home/acrocephalus/ (rw,async,no_root_squash)
and this is my /etc/fstab file relevant line on the client side
Code: /home/acrocephalus/AcrocephalusServer/ nfs rsize=8192,wsize=8192,timeo=14,intr
Then, I mount the system using the command
sudo mount /home/acrocephalus/AcrocephalusServer/

how to mount the NFS with full read-write permissions?

Networking :: After Server Crash Nfs No Longer Mounts At Boot

Networking :: Make NFS Mounts Easy To Find For OpenSuSE 11.2 Users?

Oct 29, 2010

Our organization uses OpenSuSE servers (NFS/LDAP/SAMBA/more...) and are in the works migrating all the workstations for users to SuSE from Windows as well.

I like how in windows the mapped network drives are all listed in My Computer. OpenSuSE has a similar "My Computer" that lists current drives, and general PC info (in KDE, which is what we use in the office). Is there a way to list mounted drives in here, so that users can easily find the network drives? I'm open to alternatives to listing it in SuSE's sysinfo page, as long as it doesn't mean telling my old school windows users, "oh yeah, all your network drives are in /mnt/shares/...they wont have a CLUE what that means. It HAS to be easy for them to navigate to.

My attached image is just a screen shot of SuSE's "My Computer" so you can see where I would ideally like to put the shares.

Slackware :: Different Mounts Of Same Ext Hd

Aug 8, 2010

On my same box are two slackware-installations: one slackware64-13.1 and one slackware32-13.1.

There is an ext Hitachi-hd plugged on my box. With slack64 the ext hd has the uid of the normal user, so I can copy files onto it as user. With slack32 the ext hd has the uid of root, so only root can copy files onto it.

The mounting is "on the fly" with power on/off of the ext hd and NOT set in fstab. How can I change the "automatic" mount-defaults in slack32, that the uid is set to normal user instead of root?

Networking :: User NFS Mounts - "mount - Only Root Can Do That"

Jun 25, 2010

I am working from RHCE Study Guide 5th Edition by Michael Jang. Lab 1 for Chapter 6 says that I should be able to mount a remote NFS share as an ordinary user under their home directory.

However, mount requires root unless it's defined in /etc/fstab with the appropriate options. So would the following never work for a user?


I could define it in /etc/fstab, but then I would have to specify a "general" mount point for the mount, like /mnt/nfs and not specific to a user like the lab suggests above.

Is the book wrong on this? Even the answer for the lab makes no mention of using fstab to mount as non-root user and the above command is correct according to the solution.

Ubuntu :: Missing Mounts Without Any Reason

What the hell is wrong with 11.04? One day I wake up and find all of my mounts functioning properly, the next day many are missing. I've been running with the same fstab for years. The problem isn't only with cifs shares, but even with internal ext4 shares. I'm so disgusted I'm about to run to Windows after 10 or so years of prompting people to move to Linux.

Server :: Way To Monitor NFS Mounts?

Let's say I have a machine exporting 3 paths via NFS.


I would like to know if there is a way to determine how many clients have each export mounted at any given time. I don't necessarily need to identify which client has mounted what, just the number.

/exports/foo is mounted by 3 clients
/exports/bar is mounted by 1 client
/exports/bla is mounted by 0 clients

Ubuntu :: Totally Screwed Up Audio And Mounts

Jun 29, 2010

I had it working perfectly everything worked including my headset. The only problem was certain programs were too quiet for my taste and seeing as i have a laptop and cant manually turn up the speakers i looked for a solution and found

Code: [URL] I followed those directions to try and boost the poor sound volume that has plagued me in ubuntu distros. Instead sound sparsly works. It is quieter than was, and if chrome is open at all no sound will play at all in rhythmbox or amarok(the play button dont even works it just sits at 0:00) Only after chrome closes does it play my music files again but only on this partition. As now my windows partition thats also located on this fakeraid just magically disappeared.

how to fix this as i dont even know what i did to begin with. how i can trash kde and start over from within gnome(havent tried to see if it works there yet though) EDIT: Logged back in to gnome and everything works fine. The missing partition is auto mounted like i wanted, the sound is perfectly fine. Obviously something got screwed up in the kde config but i dont know what or what to look for as i have never used kde before.

Ubuntu :: NFS Mounts Failing At Boot With DNS Errors

Jul 14, 2010

I have several NFS entries in my /etc/fstab file. Each entry generates an error during boot (from /var/log/boot.log):mount.nfs: DNS resolution failed for macpro.dpc: Name or service not known mountall: mount /mnt/BaseLines [656] terminated with status 32

This occurs even if I specify an IP address in fstab rather than a host name. I was really surprised by that. The odd thing is that by the time the system is up, not only is DNS working as expected, but the NFS shares are mounted as expected. I'd just ignore it for now, accept that it prevents Apache from starting since some of the server's files live on the NFS shares (this is a development system). It appears that the DNS resolver isn't running when the mounts are attempted and that they are attempted again later, after the resolver is running.

I did an
$ sudo apt-get update
$ sudo apt-get upgrade....

Ubuntu :: Boots And Mounts A Dummy Directory?

Oct 17, 2010

I had a problem with Ubuntu 10 trying to mount a non-existent directory, mount/DRIVE_F/R&RMT . It would post an error message, wait for acknowledgement (or timeout).

The only cure for this incredible annoyance was to manually create the missing directory and path.

This works, EXCEPT THAT now instead of the (Gnome) desktop coming up, the empty directory I created comes up, and I have to close or minimize it.

I can't find where in the boot process the command to mount this occurs.

I need a clear explanation of the complete boot process from cold boot to Gnome GUI exposition.

Ubuntu :: Accessing Network Mounts Via Terminal?

Is there a way to access remote mount points that were created within the "Places" dropdown or within Nautilus? I haven't been able to locate a mount point for these.

I know I can create a mount point using fstab that will solve my problem but I was hoping for something using these automount procedures as it's really clean.

I just want a way to access these remote shares via terminal when created within Gnome.

My iPhone no longer mounts and I have no SSH option! And I have not updated anything and made changes. I have tried 2 different cables and different USB ports.

Ubuntu :: Getting /proc/mounts Error After Moving To 2.6.32

I recently installed a newer kernel to get the open source driver for my ATI card, but am now getting the following error between booting and logging in: Warning: unable to find suitable fs in /proc/mounts. Is it mounted? After doing some research I can see it has something to do with apparmor. My questions are:

1. Can I somehow get rid of this error message? Or rather, is there a solution for this problem?
2. If not, as seems to be the case, is my system safe and secure? Will I face any issues by ignoring this error?

Debian Configuration :: Disabling Usb Mounts ?

Apr 7, 2010

Let me quickly state that I am returning to Debian after quite a long break. I am trying to relearn some things. I suppose I'm somewhat old school. As in I originally installed from rawright, back in the days when you had to do practically everything by hand. I was quite happy with config and make. I actually learned a ton back then, as I started out knowing nothing. I guess I can learn to catch up with the modern linux world.

Anyway here is my question? In the old days if I wanted something not to be mounted I would simply comment out the entry in /etc/fstab. I notice that my USB drive is mounted but does not appear in the fstab. It is in mtab, and lsusb does show it.

If I wanted to secure a system, but not totally remove usb support from the kernel, how would I prevent the automounting of USB drives? What are the configuration files that govern their operation?

OpenSUSE :: Ipod Mounts In Gnome But Not Kde

Jun 1, 2011

My kids each have an ipod touch. Occasionally I connect them to my laptop and use dolphin to pull the pictures off them. I've noticed recently that the ipods don't automount in kde. I know that they were mounting under suse 11.3 (kde 4.5); I can't remember whether they ever mounted under 11.4 (kde 4.6.3). Last night I needed to back up the ipods, and I found that I could do that if I booted into gnome (they mounted right up as volumes in gnome), so the issue seems to to be kde-specific.
