Ubuntu Servers :: Can't Cd To Nfs Mount?
Feb 9, 2011
I have a file share server hosted by a CentOS 5.5 install. All the other Linux CentOS 5.5 boxes can mount the share no problem.A Ubuntu Server 10.10 box however seems to be able to mount the drive, but then says cannot cd to the folder in question. I have installed the nfs-common package.The CentOS share has the following in its exports file:/media 192.168.1.0/24(ro,sync,no_root_squash)This allows use of mount server:/media /myfolderThe ubuntu box has the following in its fstab file:server:/media /myfolder/media nfs defaults 0 0I've tried setting up the users on both boxes to match, but this seems to have no effect. The exact message is:cd: <random number each time>: can't cd to media

I run a headless Ubuntu 8.04 server, which acts as a web, email and file server. I am sticking with 8.04 as it is a LTS release and will upgrade to the next LTS when it is released.
I have two external USB drives, that I need to mount at boot. I have been using /etc/fstab up until now, with the following entries:
Code:
However, as I gather from doing searches is quite common, occasionally I get an error during boot (causing the system to drop to a recovery shell) because the USB drives take time to wake up and the system hasn't found them by the time it reads /etc/fstab.
From doing searches, it seems there is nothing you can do to fstab to fix this, so you need to mount them using an rc.local script instead, using:
Code:
The problem is, as I have two USB drives, their /dev/sdxx location changes between boots. I thus want to use UUID codes as I do in fstab, however I haven't found anything about this.
Does anyone know how I can use the mount command and UUID to mount a drive in rc.local and what options I have to use the mount the drive with the same options that I am using in my fstab entry? Obvisouly, I can't refer back to fstab using the mount command, because then I will still get the boot error issue if they are listed in fstab. And there is no space internally for the USB drives as there is already two internal drives.

Linux box info: root@mytestbox:~# uname -a Linux mytestbox 2.6.32-30-generic-pae #59-Ubuntu SMP Tue Mar 1 23:01:33 UTC 2011 i686 GNU/Linux
Windows box info: Windows Server 2008 SP2 Enterprise I've verified via --verbose output that mount.cifs is indeed processing the passed on options.
root@mytestbox:~# mount -t cifs //10.1.1.10/Test /root/testwin --verbose -o credentials=/root/testcreds,rw,nocase,noperm,noacl,nounix,noserverin o,iocharset=utf8,file_mode=0777,dir_mode=0777
[Code]...
Yet, when I type mount all it reports is (rw,mand). The share works just fine, and I can see the masking (all files are showing as rwxrwxrwx as expected etc) but mount is not listing the options?!
Is this normal expected behavior? Is there a bug report on this? I've google'd to the best of my capabilities and could not locate any such information which is why I decided to hit the forums prior to filing a bug.

I am trying to mount my usb printer in Ubuntu Server 9.10. I'm trying to do this so that the usb printer will be picked up by vmware server so the Windows XP guest I have on there will then be able to access the printer as if it were hooked up to it directly. I found a few posts online and this is what I've done so far. I found in a couple of posts that they said I should uncomment out the following lines in /etc/init.d/mountdevsubfs.sh. Well I found that the file didn't exsist. Someone posted up their copy of it so I copied that code into the mountdevsubfs.sh script. That code is the following:
Code:
#! /bin/sh
### BEGIN INIT INFO
# Provides: mountdevsubfs mountvirtfs
# Required-Start: mountkernfs
# Required-Stop:
[code]....
I also added this line to the bottom of my /etc/fstab file
Code:
usbfs /proc/bus/usb usbfs auto 0 0
When I go ahead and run the script it errors out on this line:
Code:
. /lib/init/mount-functions.sh
I went to go look in /lib/init and the mount-functions.sh script doesn't exist. I've googled this and I haven't been able to find anything. why am I missing /lib/init/mount-functions.sh and how can I get that script?

I just changed the os on my media server from Windows Home Server to Unbuntu 10.4 server. I got most of it working (samba, twonkymedia)
The only thing i have left to get working is the backup of that server. I installed bacula as i beleive it will do the job (unless someone has a better and simpler to configure idea) and i would like it to backup to my external usb 1Tb hard drive. I am able to mount the drive manually but this server gets turn on and off often to save power (and cut the electric bill) when not in use. I tried adding a line to fstab but when a do that, the server gets stuck on the startup even with the drive turned on. I read somewhere that i should use the UUID of the drive as it could change from sbd1 to sbh1 on restart so i did, same result.

I've got a 10.04 server install, on which I installed a basic gnome desktop. But I've never been able to automount usb drives or DVD/CDs!?but seem for desktop. May relate to not having standard gnome install? I don't have users-admin to try that, and don't see install package.

I am very new to Ubuntu and have been having trouble mounting my FreeNAS drive. I installed Ubuntu 10.10 on partition sda2. I wanted to keep FreeNAS completely separate from here, so I used Virtualbox to host FreeNAS as a guest o/s on a second hdd, sdb1 mounted at /media/NAS-Data. I can access the NAS from all computers except my Ubuntu box. I have CIFS/SMB and NFS (among other) services enabled on FreeNAS.
I would like to run a program that needs access my music. I followed many of the "How To's" on the forum, but am not sure if they didn't work or if my setup is different and can't work the way that has been described. My last effort was to mount the file system using NFS, but I get a timed out error.
When I run showmount -e 192.168.0.44, result is /mnt/cNb-NAS-data 192.168.0.0. I've tried many variations to mount, but none have worked. For all I know, again I'm very new to Ubuntu, the file system is already considered mounted (/media/NAS-Data), and I just need to find the correct path to access my data. This is probably obvious, but when I navigate to NAS-Data, it has the Virtualbox NAS.vdi file.
Was hoping someone might be able to either help me get the correct path name or mounting instructions in order to view these files from Ubuntu.

I want the users of the other machines, which have accounts in my server, to mount their home directories in the server. I managed to do everything, except that for the moment I can only mount their home directories by being the superuser of the server, a privilege that I don't want to give to the users. Also, I don't want their home directories to be mounted automatically. Thus, from a "normal" filesystem share, I want to: 1-The home directories of user in other machines be mountable in the user areas of the server (I can do that already).
2-I want that the users be able to mount by hand their directories, so that the directories are not permanently mounted. Currently, I can only mount and umount being the superuser of the server. I don't want to give superuser privileges to all server users.
3-I don't want their directories to be mounted on startup (otherwise I could simply add the mounts to /etc/fstab). Thus, does anyone knows how can I give the users the privilege only to mount a specific filesystem?

I've been trying to set up a Linux-only network and currently have a working DHCP, DNS, LDAP and NFS server, with a client that can authenticate with the LDAP server and a central /home folder.However, if I wanted to share folders on the NFS server, how would I make the share available to, for example, a particular group of users in the directory?I've never used NIS(+) on a network, but believe you can add a 'group' of users in the /etc/exports file--simples!Does anyone know of the best way to do it (even better anyone who is doing this in a production environment)?

I recently reinstalled my file server (moved from fedora to ubuntu server). Now I cannot mount my nfs share from windows 7, mounting from mac osx works fine. In windows I either keep getting "the semaphore timeout period has expired" or "an unexpected error has occured". Does ubuntu need some special magic to allow windows 7 to mount an nfs share? This is my exports file
Code:
/home/ducky101/ 192.168.1.*(rw,sync,insecure,no_root_squash)
/home/ducky101/mnt/EXTRN2 192.168.1.*(rw,sync,insecure,no_root_squash)
/home/ducky101/mnt/EXTRN3 192.168.1.*(rw,sync,insecure,no_root_squash)

I have recently had a problem with my 10.04 server machine. It will not boot, it seems to be taking forever on the loading screen (normally headless server, but I connected monitor when I couldn't ssh), but that's not why I'm here.
Knowing that I do rsync backups every night at midnight of my machine I just bit the bullet and formatted my / partition. Reinstall went fine, I turned off automatic updates (I suspect an update caused the problem) But now I cannot mount my jmicron raid 1, which is where my rsync backup is (doh!).
sudo fdisk -l
Code:
WARNING: GPT (GUID Partition Table) detected on '/dev/sdd'! The util fdisk doesn't support GPT. Use GNU Parted.

On a Lucid server, dnsmasq is happily running DHCP together with a local DNS; although, in setting up NFS, I seem to have a small problem... I have /etc/exports referencing the hostname of the clients but these IPs change when the DHCP lease is renewed. Unless I restart NFS or run exportfs, I cannot mount the exports on my clients. I know that it would be good to make the all the addresses static; however, I was wondering whether there is another way to configure NFS such as possibly adding in a script to continually monitor /var/lib/misc/dnsmasq.leases and re-export accordingly?

I've built a customized 2.6.32 kernel over Ubuntu 10.04 server (physically) -note: it is the same version that comes with the livecd-. Then I added my stuff, cloned the disk, applied it to 3 different hardware boxes and it works perfectly. But when I put that image on a VMWare Workstation 7.1 or VirtualBox machine it doesn't load... I get a "kernel panic: not syncing vfs unable to mount root fs on unknown-block 0,0". So, I've created a new vm, I've installed ubuntu and it booted without a problem.
I ran my kernel patching as I did on the physical machine, but when I rebooted with the new kernel, I got the same error. So, the problem seems to be something in the customized kernel, but specifically going over virualized copies. By the way - In a previous version, specifically Debian 5 with kernel 2.6.18, I did the same stuff about a year ago and the machine loads perfectly in any virtualized environment. Then, the only thing left to think about my problem is that some grub parameter or kernel driver or something is messing up with booting. The customization of the kernel is only the patching for IMQ stuff.

I've installed Ubuntu Server, and Webmin following this guide, and all is well so far... I've mounted some drives with some pre-existing data on them, and can view the data on those drives. But I have one drive that I can't seem to mount, and I'm pretty sure there's data on it. But I can't seem to find how to identify what format the data is in, ie.. ntfs, ext2, ext 3, etc. Its likely pretty simple, but how can you identify the drive format before you attempt to mount it?

My 11.04 installation is running beautifully in VM on ESXi. I'm trying to add storage so I added the disks, assigned them in vmware to the vm, then tried to mount them when I received the error code...
my setup:
HP Microserver, booting vmware from USB drive. Hardware RAID card (Adaptec RAID 2405), 2 x 250GB HDD in RAID1 (datastore1) with VM's, 2 x 2TB HDD in RAID1 (datastore2) - the storage I'm trying to add.
A search of the above errors yielded many results, all of them were different scenarios to mine.

I had everything working okay, but suddenly I couldn't mount an NFS share from one specific machine to another specific machineIn detail, I have a server (machine 'S') with a share '/big' exported. All hosts on the subnet (ie, 192.168.1.0/24) have rw access . A client machine, 'A', can mount the share S:/big. But client machine 'B' cannot. Not only are they on the same subnet, but this had been working for quite awhile. Also, I have another client 'C' and it can still mount the server's S:/big share.
When I say that 'B' cannot mount S:/big, what really happens is that the mount call just hangs for a long time (10min+). There is nothing in dmesg or /var/log/messages either.I don't think I did anything that would have changed this. The lines in '/etc/exports' are still the same. Machine 'B' has complete net access to 'S' (ping, ssh, etc), and 'B' can even mount samba shares on 'S'. Just not nfs.

I have upgraded one of the computers on my network to Fedora 14 (previously Mandriva 2010.1). There's a directory on another machine that I want to mount on this one. The directory can be mounted OK on two other machines in the network (including one running Fedora 13) and, before the upgrade could be mounted on this one, so the nfs server is OK.
If I try to mount manually I get the following:
[root@lipwig Documents]# mount -v 192.168.8.4:/backup /mnt/librarian/
mount: no type was given - I'll assume nfs because of the colon
mount.nfs: timeout set for Tue Feb 8 12:17:00 2011
mount.nfs: trying text-based options 'vers=4,addr=192.168.8.4,clientaddr=192.168.8.12'
mount.nfs: mount(2): Operation not permitted
mount.nfs: trying text-based options 'addr=192.168.8.4'
mount.nfs: prog 100003, trying vers=3, prot=6
[Code]...
/etc/hosts has the names and ip addresses of all the machines on the network so the reverse dns lookup (which I have fallen foul of in past years) shouldn't be an issue. So I'm kind of out of ideas. I don't recall there being any problem accessing this mount with Fedora 13 .

I am trying to mount /NFS as nfs mountpoint on two servers ( A & B ) having OS OEL 5. After mounting the nfs filesystem, both of them behave normally for around 10 mins and after that the NFS file handle become stale and the mountpoints dont respond. While executing df -kh, the output hang out and the /var/log/messages show the following message:
May 27 15:48:56 earth mountd[3078]: Cannot export /NFS, possibly unsupported filesystem or fsid= required
May 28 04:04:20 earth kernel: nfs: server nas not responding, still trying

I have the following scenario:
- Server installed in wired network. The server has a static IP. It has Ubuntu Server 9.10 installed.
- I have two Ubuntu notebooks (Ubuntu Desktop 9.10) and I want them to connect (mount) to the server on bootup (fstab or equal) if the network is available.
- I don't want to store the password in cleartext in the fstab file. So what other options do I have? What would be the most common practice here?

I recently set up a Samba server (Ubuntu 8.10 desktop) in a Social Businness Office. in there have different laptops and OS.
Here is how my smb.conf file look in the share section.
[private folder]
path = /path/to/private
comment = private
valid users = user1 user2
directory mask = 0777
[Code]....
It work fine for Win and Ubuntu, but access this folder with Mac OsX gives this error:
smb_mount: open session failed!: syserr = Broken pipe
It seems that authentication is ok, but for some reason it cannot mount the device.
I know this is not the right place to talk about OsX issues.
I would like to exclude if there are some options I miss in the smb.conf.

I've a few group shares setup with samba and a PDC (using windows 7 clients) and the home directory for each user gets mounted automatically. I've configured group shares and only members of the respective group have access to them, but my question is how do I tell samba to automount group shares based on the user group?
