General :: NFS Mounted System Size?
Jan 13, 2010
I have an NFS server running an older version of AIX that exports two disk partitions. Let's say /1 and /2I also have an NFS client running Fedora 9.I am able to NFS mount /1 and /2 from NFS server under /mnt/1 and /mnt/2 on the client.If I do a df command on the aix server,I see that /1 is 2Gb total and 1.7Gb is usedand /2 is 2Gb total and 1.4Gb is usedI see the same if I do a df command on the NFS client (Linux)Now, the confusing part is here: in the GUI of Fedora, if I go under /mnt and right click on /1 and check folder properties, it tells me that there is ~ 54 000 files (which i assume is the correct number) for a total of 5.3Gb! And for /2, properties indicate 1.2Gb. Where do these extra 3.6 Gb come from on /1...? and even the smaller difference for /2 confuses me (but this might be just the way different systems round off large numbers)?

How can I see all the physical hard drives on my Ubuntu system — regardless of whether they're mounted — as well as their partition info, sizes, &c.? I have three physical drives, but only one seems to be mounted. I'd like to mount the other ones too, as I have some data on them.

My university has a system set up where each class has its own directory for the professors to publish and receive files. These directories reside under a directory in /home which happens to be a mounted disk and are accessible anywhere in the system by referencing ~csXXX where csXXX is a sub-directory within that home directory. How are they doing this and how can I do it on my own systems?

I am using Gentoo Linux and for a while now, the root file system is mounted read-only on booting. For obvious reasons, this is quite annoying as most services do not start up correctly (I do not use a separate file system for /var). After the system is up, I have to log in, remount the root file system read-write, fix /etc/mtab, mount all other file systems in from /etc/fstab and then start up all the missing daemons. I know that there are ways to make a system run properly with a read-only file system, but I would rather restore the old behaviour of a writable root file system.
The strange thing is that after running mount / -o remount,rw, the file system is mounted in writable mode without any errors. I suspected some problem with fsck, but now I have disabled automatic file system checks on the partition (tune2fs -c0 -i0).When I run dmesg, only these lines mention the partition at all, although I am not sure if not something gets lost because /var/log is not writable:
EXT3-fs (sda5): mounted filesystem with writeback data mode</code>
EXT3-fs (sda5): using internal journal
The line in /etc/fstab looks like this:

I have mounted a iomega file system on a cetos os machine using
mount.cifs //filserver-ip/directory /home/my-home/mounted-file -o
user=username
(** mounted as root) The mounting works fine.
The problem arises when I try to create a sub-directory inside the mounted directory. All the newly created sub directories become write protected.
I am accessing this file system from R software and it needs to write/create directories in side this mounted directory.
how can newly created sub-directories will become automatically writable, so that R can create new sub-directories and write data inside those directories.

Our LAN is connected to internet via leased line, and it is getting slow at peak times.We doubt someone might be downloading files of huge size.Instead of SSH-ing into each system and finding out the download size (ethstatus), is it possible to view from a network bandwidth monitoring software?

- first drive is the system
- I mounted the 2nd drive (ext3) on a folder, but the Size is 941.89 MB instead of 149Go
- same for drive 3 monted on another folder, but the Size is 941.89 MB instead of 149Go

I have an ntfs partition that I wish to access as a normal user(non-root). For this I did the following. As root I created a folder /windows and did a chmod 777 -R on /windows. Then I added the following line to /etc/fstab
Code:
/dev/sda3 /windows ntfs-3g defaults,nosuid,nodev,umask=000 1 0
Now, the partition is mounted alright but the problem is that when any other user (non-root) creates a files in /windows (say by executing touch newfile) the newly created file has the owner and group set as root. The non-root user can create the file and he can also delete the file, however, he cannot change the permissions of the file and also the owner:group is always set as root:root. How do I get across this problem, i.e. how do I mount a partition, so that a non-root user can also change the permissions and ownerships of the files he creates.

I have a DVD-R made by a friend who has found no fault. It will not play in my Panasonic DVD-recorder, and when I put the disc into the computer optical drive it does not appear in the places list, though the drive is mounted. I can display the video using Gnome Mplayer (but no other application) and I can copy to ISO using Gnomebaker, but this creates another unreadable disc. Gnomebaker finds a bad sector 120832 at 41% of the disc. If I could read the VOB files on the disk I might be able to make a playable copy, but it baffles me that Nautilus cannot read the disc.

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.

Under my 'Places' in my file manager, I have a '21 GB file system' How can I
1. Have that 21 GB auto mounted every time I login? I now need to right click and select 'mount'?
2. Give it a name so that it won't call 'a9f28af4-71db-4e49-8c05-f652bf808cc1/' under my directory '/media/'?

A non techie friend has helped an even less techie friend by contacting me by email to discuss an ailing laptop. A few emails were exchanged, with more details, and it was not looking good because it seemed that suddenly the CD drive was not responding, nor any USB devices, the wireless icon was gone, but Ubuntu still seemed to work (for now), with wired ethernet also working. I was struggling to think of what could be done, with the favourite routes of Live CD and Live USB apparently gone.
After a few more hours - another email: 'It's now working! After so many reboots it checked disc for errors and repaired itself! Is there some way of doing that when needed anyway?'I see there is 'Disk Utility', and this would presumably fit the bill, but how does it do checks and repair when the damaged file system is being run, and is currently *mounted*? I thought utilities like fsck(?) could only be run on unmounted file systems? Have I misunderstood the disk utility fs check repair function? And anyway, what might be a good answer to my (nontechie) friend's question 'After so many reboots it checked disc for errors and repaired itself! Is there some way of doing that when needed anyway?'
For the record: (quote) It is a toshiba EA60-155 Model number PSA67E-00300C8J. He put in extra ram to install ubuntu. He thinks he may have deleted something! There is a 'trash' file on his USB drive with loads of stuff in it and he doesn't know how or why but because it won't now read the drive on her laptop we cant replace it! (end quote)

I am using back in time to back up files from home and from another mounted directory on my system (ntfs). The back-ups are occurring automatically and appear to be complete; but, I cannot delete old back-up snapshots in the backintime GUI Also with sudo nautilus or as root in terminal with (rmdir) I cannot delete the snapshots. My drive is filling up and rather than uninstalling back in time, I would like to simply delete the unneeded snapshots. How can I delete these files? Is there an rsync file that I should configure to delete these? My expectation of backintime was that it would back-up at the requested frequency and not create complete duplicate copies of the files, but, use symbolic links to unchanged files. How can I verify if this is the case? Does the cron file control this>

I just found that I could perform write operation using a normal user account to a file system I mounted with the commands as followed:
sudo mount -t ntfs /dev/sda1 /mnt/disk/
This is the corresponding entry in the output of "mount" command:
/dev/sda1 on /mnt/disk type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096)
As far as I remember, when using a normal user account, I had to use "sudo" to perform any write operations (mkdir, rm, etc) to a device mounted using "sudo". But now it seems to be changed.
Do I remember wrong, or did Karmic have any updates change this setting? (I never manually changed user settings, except that I added a root user, but I never used it.)
OS: Karmic(up2dated)
Kernel: Linux stephen-laptop 2.6.31-17-generic #54-Ubuntu SMP Thu Dec 10 16:20:31 UTC 2009 i686 GNU/Linux

mount an NFS directory as a regular user (which doesn't have sudo rights) because a suitable entry (i.e. with the user option) is defined in /etc/fstab file.But, when I mount it, I am not the owner of it! The owner is the default superuser of the system. So I don't have write permissions in the mounted directory.

I'm running an Acer Aspire 1830T-3721 dual-booting Windows 7 with Ubuntu 10.10 (Desktop).
Background: So first I dropped my laptop a couple feet while Windows was running. The laptop immediately shut off and then tried to boot. Booting Windows results in an unfortunate "Windows has encountered a problem communicating with a device connected to your computer. The error can be caused by ... faulty hardware ... Status: Oxc00000e9 Info: An unexpected I/O error has occurred." But Ubuntu booted fine, and could access my NTFS files fine, so I was trying to work on the problem from there. I try a few utilities, looking at the partition table, etc without actually applying any changes.
Then I run a fsck on the drive. It loudly warns me that if I continue on a mounted drive, then I'm going to mess things up. In a moment of stupidity I push on, thinking that surely it would ask me for more configuration, or confirmation, before actually starting. The fsck runs for about 1 second before I Ctrl-C it, running some preliminary stuff and then just starting pass 1.
After this, Ubuntu won't boot anymore. Instead, it hangs just after the init-bottom script runs. If I boot with init=/bin/bash, I can get to a shell, and see that my file system is still there, but not sure what else to do.
I've been running off of a SysRescCD LiveCD, from which I've looked at the drive with testdisk. Testdisk reports that "the hard disk seems too small" while showing me the partition table.
I ran a fsck on the Linux partition; it fixed a bunch of things. There has been no apparent effect on the boot behavior.
I can access all my files, back them up, and reinstall Ubuntu, but I'm hoping there's a better solution, perhaps one that will also help me repair my Windows installation (but I'm looking at one problem at a time here).

I have an NTFS file system nfs-automounted on our RedHat servers. Users can read and write to the file system no problem, and can create new files, edit them, and delete them to their heart's content. The only issue is that utilities such as "dos2unix" cannot create temporary working files:
$ dos2unix events.0818.dat
dos2unix: converting file events.0818.dat to UNIX format ...
Failed to open output temp file: Operation not permitted
dos2unix: problems converting file events.0818.dat
This isn't limited to "dos2unix"; any other utility that creates a temporary working file gets the same problem. If I copy the file to a local file system like /tmp, it works fine. Here's the kicker: this works fine on Solaris systems. I can take the "dos2unix" utility over to a Solaris system that has that exact same NTFS file system automounted via NFS, and it works. No issues creating temporary working files at all.

I am running Fedora 15 along with Windows 7 on my Dell laptop. Yesterday, when I was trying to install TeX Live, it stopped in between saying that there is no space left in File System. Even though I have space in my hard drive volumes, space seems to be running out of my system partition which is only 9GB in size (I guess!).I am posting a few results that might help you guys. I have an unformatted 15GB partition. How can I add it to my system partition? And is my var folder too big (1.5GB)? If yes, how do I backup its contents and then delete them? Additionally, the File System shows a folder 'media' (89GB) which links the C: drive that contains Windows 7 and my personal files. Should it remain that way or should I separate it? If the latter, how? I just couldn't find any.
Code:
#df -h

I was getting low disk space notifications so I used LVM to increase Ubuntu's volume from 10GB to 50GB. LVM and Disk Utility show the correct new size, but System Monitor and the Properties of the File System (in Nautilus) show the old, smaller size. Do I need to update something to get them to see the new size?

I was using UBUNTU and still do, but I dual boot UBUNTU/Slackware now and my Linux knowledge has increased so much. This forum has been right there with me for the last couple weeks and I was reticent to post a question until a knew I had exhausted the available sources. So here goes.....Can I change the font size of the system shell that begins at startup (with the boot info and stuff). I really like using this shell as user. The thing that would make me nuts for it is if I can make the text a bit smaller. I have a 1920x1200 display and could really take advantage of all of that "real estate." The other posts related to this seem to focus an a broken configuration from the beginning, but my install is SWEET. Can I change this or is it baked into the system?
