Networking :: Nfs Mount At Boot Shows As Mounted But Is Not
Nov 17, 2010
I setup my client to mount some nfs mounts at boot but although they seem to be mounted, they are not! Before I give the details, I'll start by saying this is not a wifi problem. I'm using a good old wired connection. The server runs NFS3 with the following line in '/etc/exports':
[Code]...
I have tried the following nfs options in the fstab as you might have noted above: _netdev,auto,bg,retry=10. None of them seem to fix the problem. I realise a quick hack at boot time would fix this in an instant but I'd like to figure out why this is failing.
When my laptop boots it successfully mounts the NFS NAS and I get an icon "My NAS" on my dekstop that points to the NAS. If I double click on the icon it opens my file browser and I can browse thru my NAS fodlers.
What I see on the left hand side of the file browser is that I have to entries for My NAS. One of it has a button to shows that it is mounted and the other does not.
If I go to Places I also see 2 entries for "My NAS". One of it takes me to browsing the NAS and if I click on the other it says "Unable to mount ... busy or already mounted". Which makes sense.
Created partitions, some of them LVM, in a server, say A. Did the same for another server, B, but created one more LVM partition.
Installed RHEL in A, and some other applications. Made dump files for each partition of A and restored all of them them in B. No error in that process, except B wouldn't boot. Did chroot /mnt/sysimage and grub-install /dev/sda--still no good. B came to a halt with GRUB> dispalyed. <tried many things many times.. searching Googles..but w/o luck) Gave up, and restored the bootloader part using OS CD -- I say restored because now B boots ok and I can see application that I had installed in A. So far so good.
Problem: that extra LVM partition is missing! I did not knowingly overwrite it, so where did it go? Somebody is keeping it from being displayed!
Is it the grub.conf that tells the OS what to mount and what not to? If yes, problem is , grub.conf is missing in B. In A, it is in /boot/grub/. df -kh shows other partions (some of them LVM) just fine.. what is going on?
I tracked a file called menu.lst in a strange place, in /usr/share/doc/grub-0.97.. but I didn't see any entry that loads partitions.
Just moved to Ubuntu from XP. Whole process has gone very smoothly, but left with a small problem (i.e. it isn't actually affecting usability) that I don't seem to be able to fix and can't find on forums/internet. I also have a problem with the Floppy drive, but I've seen that problem elsewhere in the forums.
It's a dual boot system with both NTFS and Ext4 drives. All are visible and fully accessible. I decided to convert one of the NTFS drive to Ext4. That appeared to be successful and was successfully remounted as an Ext4 drive. The drive label is "Data". I did have a bit of a problem getting it remounted so that I could see/use it under my log-in as opposed to just under root. It's at this point I think that I did something to create the problem.
I now have two entries for "Data" in drop down menu for Places. The true one is shown as a standard hard drive icon, but the false one is shown as a different icon - possibly an external drive icon (note that the floppy drive is also showing as the same icon and I can't access that, but I've seen that's a problem elsewhere in the forums).
I can write and read to the true "Data" hard drive. If I click on the other false "Data" icon, I get the message "mount: /dev/sdd1 already mounted or /media/Data busy mount: according to mtab, /dev/sdd1 is already mounted on /media/Data". If unmount the true drive and try to mount the false drive, the system mounts the true drive instead. If I log into nautilus as root, neither the false data drive or the floppy appear in the left hand panel.
I am looking for such a tool, very much like the one that is on Windows 7, where you can basically with one glance see how much of a volume is occupied (graphical bar) and that for all mounted volumes. I have been looking for this, but so far I have not found it.Also, important: that it is auto updated. So that it is not like a report that was generated and then does not change anymore, but a live thing
I have a server that NFS exports the /home directory out to other computers. On the desktop they all work great, but on a wireless laptop, this is where the problem occurs. The wireless enables after the person logs in, rendering the NFS export /home useless on the laptops.Is there anyway to have the wireless enable correctly on the boot so that NFS can mount properly at boot also?I'm using Fedora 11 (32bit) with a wireless router that has a security of WPA-PSK [TKIP] + WPA2-PSK [AES]. I could switch to some of the older versions if necessary to get this working.
I'm trying to mount a mounted NFS share. I have a server that connects through VPN to a network, that has the NFS share exported. I am able to successfully mount the NFS share on that server, in /media/iSCSI. Now I want to share this NFS share with other servers, that are on the same network as the VPN-ed server, but are not connected to VPN. When I try to export the mounted share, I get:
I have been having the hardest time with this. I am trying to mount a share on a Ubuntu 10.04 system from another Ubuntu 10.04 system.
The system with the share has the OS on one drive and then data on a second internal sata drive that is mounted. The share is on this second drive.
I can see it when I browse networking from the other system but it won't mount. I get a message saying that the folder contents can't be displayed. I do not have permissions necessary to view the contents...
I have tried setting the share folder permissions as permissive as possible but can't get passed it.
I have two servers, 82 and 70.My exports file on 82 reads /...70(rw)on 70 I have a mountpoint called mnt_for_82I execute on 70mount -t nfs -o rw ...82:/ mnt_for_82I go to server 70 and indeed can read and travers the mounted subdirectories. However, I try to create a file or subdirectory under the mount point on 70 and I get a *Permission Denied* error.I'm sure there is a simple explanation for this issue as well as a correct nomenclature for what I'm trying to do in nfs
I need to know particular mount point mounted or not before send data to that mount point.Are there any commandsi used this command. mount -t nfs 172.16.102.50:/root/ESSR_share /root/shared_storage/pc50 -o rw,hard,intr but it take long time (when machine(172.16.102.50) is not available)
I have a secondary 250GB disk of which I created a 50G partition on to try and set-up an LFS system. I finished with the LFS system and now I want to destroy the partition and reclaim all of the 250GB. So i simply ran fdisk /dev/sdb and deleted the 2 Linux partitions ( one 83 and one swap). I then created a new partition as primary partition #1. fdisk appears to see the entire disk....I'm able to start at cylinder 1 and end at 30401 which is 250GB, however when i mount the partition it's shows as only 50G.....What the hell is going on here???
i'm installing a Linux system just simply following guide by fellow friends comunity. Currently, my box are having 2 HDD with 35GB each capacity. Displaying in GNome (36.2 GB Encrypted Data). During installation, I'd selected :
*Remove Linux partitions on selected drives and create default layout *The "Encrypt system" option
In Gnome desktop, when I right click and select mount volume, it will display : "Unable to mount location. Internal error: No mount object for mounted volume"
I'm having a problem accessing files via nfs where an iso has been mounted through the loop device on the nfs server. Basically what I am attempting to do is access the 6 CentOS 5.2 ISO's via NFS from one of my client machines. The client is able to mount the share and see its sub directories leading up to the mount point of the ISO, but the contents of the mounted ISO image are simply not visible (on the client, they are visible on the server).
I have an Olympus D-560 ZOOM. I used to be able to download pictures from the camera with: SuSE, Fedora, early Ubuntu, etc. (I still can mount and download from my camera on these systems.) I now have Ubuntu 10.04LTS and no longer is my camera recognised. I cannot make sense of the forum threads on this topic, dating back to Ubuntu 8.0-something, that generally ramble on for endless pages without reaching a sensible conclusion (it's a bug, it's not a bug, it's because of gphoto2, it's a gvfs problem, etc.). So maybe there is a definitive answer why my camera that works on other linux will not work on Ubuntu, and maybe by now there is a real fix that does not involve me rebooting my laptop into an old linux distro.
`mount' shows the camera never gets automounted. Manually `mount /dev/sdb1 /media/camera' sometimes hangs and never completes, or sometimes answers immediately `mount: /dev/sdb1 is not a valid block device'. Output in /var/log is below.What's going on, and how can I fix it? I do not use, and I do not want to use, fstop, gphoto, gimp or any other specific software to access my camera (I have tried to download using these anyway and nothing works), I just want to mount the camera as though it were a flash drive in the same manner I have always done. Remember, this does not happen on other distros or early Ubuntu.Here is the relevant output notations in /var/log/messages and /var/log/syslog.

i got problem which slows my boot to linux. Before loading Ubuntu logo in console i see fast flash with words: "Warning: unable to find a suitable fs in /proc/mount, is it mounted? Use --subdomainfs to override." What should i do? To fix that warning?
Alright so I'm currently in the process of trying to transfer a wubi install of ubuntu to an actual partition using LVPM. I need to use unetbootin with parted magic mounted (not sure if that's the right term) to my hard disk rather than a bootable flash drive. So I set everything up, downloaded parted magic ISO, ran unetbootin and selected the file everything installed smoothly. I then restart my computer and unetbootin is indeed in the boot list but when I select it, it remains at a black screen. I left it at the black screen for about ten minutes and nothing happened. I've tried a few times and nothing.
I am having a small issue on my machine. I have a NAS drive serving up media files. I have a line in my /etc/fstab such that, when the mythbuntu machine boots it is supposed to mount the network drive. This configuration worked fine for mythbuntu 9.10. I recently updated the machine up to 10.10 and since then the network drive won't mount at boot. If I open a terminal and issue: sudo mount -a, it will mount the network drive just fine.
I followed a tutorial to install XP across my entire HDD. I installed Ubuntu 10.10 "Alongside another OS". Ubuntu loads fine, but when trying to load XP, the boot screen shows up, but then the computer restarts and returns to the GRUB menu.
I saw some threads on this site and tried to type: sudo gedit /boot/grub/menu.lst
In the terminal. It returned a blank text document so I'm not sure if that information was outdated. I then typed: sudo fdisk -l
And got this:
Not sure what any of this means, but I sure hope someone else does. I would say forget XP, but it's hard to let go of some of the games and software I use. I appreciate any responses, thank you.
I tried to format the table as it appeared, but the forum corrected the extra spaces.
I have been trying to work out how to set up Fedora 15 to automatically mount an NFS share at boot time. I can mount the share interactively using 'mount -t nfs server:/usr/local /usr/local'. When I put the entry in /etc/fstab, it stops the machine booting. It tries to give me a shell ('Enter root password for shell or press Control-D to exit') or something close to that. However, I cannot enter the maintenance mode, it hangs. Same thing with pressing control-D, it hangs and doesn't get any further.
I rescued the system by booting off a CD, mounting root, and removing the nfs entry from fstab. After that it booted fine. The entry I had in the fstab is: nfsserver:usr/local /usr/localnfsro,hard,bg,intr,comment=systemd.automount0 0
I put the 'comment=systemd.automount' entry in because of some related searches I did in forums.
On my tri boot system I have a 750 GB HD that is formatted with NTFS, I would like to share it between windows and linux.How can I mount it at boot up so I can access it in Ubuntu? I want to be able to set it as the default rip drive for Kino and it won't let me!
A few months ago I have setup a server with three hard disks. The partition mapping the disks as follows:
Disk /dev/sda: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x7ca36fee
[code]....
Now I have the following problem the LVM file system don't mount properly.If I open the mount point I see only a few files of the LVM disk. If I want to unmount the disk I get the following error:
umount /data/ umount: /data/: not mounted
If I want to mount the volume I get the following error:
mount -a mount: /dev/mapper/gegevens-Data already mounted or /data busy
I was careless and deleted the Kernel using synaptic package manager. I was trying to delete the older entries but did not realize that I also selected the current one. Thus, I do not get an option to boot to Karmic at GRUB. It only shows the memtest entry and Windows XP. So I booted using the Ubuntu 9.10 LiveCD and tried the following:
1. sudo su 2. mkdir /mnt/os 3. mount /dev/sdb /mnt/os
At this point, I keep getting the following error: PHP Code: mount: /dev/sdb already mounted or /mnt/os busy I tried rebooting, making a different directory to mount my sdb to but it keeps repeating the same message again and again.
I am struggling with getting an sshfs mount mounted on system boot. I have a script that mounts the sshfs for "userA". When userA runs the script all is well - user A can access the remote filesystem, root user can't see it as expected. The basic command is: sshfs userA@remote host:/home/userA /home/userA/mountdir -p 21212 -o password_stdin < passwordfile. I can prepend the sshfs command in the script with su - userA -c and when I run this script logged in as root all is well, userA has access and all is well. If I then put this script in /etc/init.d and reference it properly in the rc. directories the mount doesn't happen. If I prepend the sshfs command with sudo, same thing. Logged in as root I can run the script and UserA has access. Run the script in /etc/init.d during startup and the mount doesn't happen. Echoing text to a log file shows that the script is being executed but no mount happens.
My swap is not mounted at boot. get it to mount again? I CAN make it mount after booting but I need to hibernate. I read that I have to edit /etc/fstab but I'm not quite sure as to what I have to do specifically.
I have just installed Xubuntu and suprisingly it did not ask me to create a partition within its installer like Ubuntu does. So now, I am left with 150mb of free space. I want to expand that amount. The problem is, I do not know where it has been installed on. I have a C and an E drive. Currently, the C drive is mounted and the E drive will not mount even if i press the mount button. Does anyone have a solution?
I have just installed ubuntu 10 on a thinkpad t410. At first everything worked swimmingly, INCLUDING the wireless. After about five minutes, the wireless stopped working, in that it seemed to think it was still connected but pinging didn't work. I've now restarted several times, and each time I restart, the wireless works for about 1 minute, then stops working. If I try to disconnect and reconnect it will not reconnect (until I restart, that is).
iwconfig shows the correct ESSID and ifconfig shows an address, and "connection information" shows a varying percentage of connection.
Does anybody know how to have partitions (not removable media) auto-mounted at boot?It would be great so I do not have to click them for first use.By the way, may it be pre-configured in ubuntu to do that for everyone?
