Ubuntu :: /etc/mtab And /proc/mounts Do Not Show Tune2fs Mount Option
May 23, 2011
I just discovered that you can automount an ext4 filesystem with acl enabled by running "tune2fs -o acl". (I knew about tune2fs but did not dare to use it until now). However, the acl mount option does not show up in /etc/mtab and /proc/mounts. Can I ignore this, or is there a way of telling the system about the actual mount options?
Edit: I can do "tune2fs -l <device> | grep acl | awk '{print $4}'" and if that isn't empty I can update /etc/mtab with "mount -f -o remount,acl <device>", but like the udev rule I previously messed with this seems lumberingly unelegant to me.

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?

I've got the F13 LiveCD that I was able to boot and use using the "nomodeset" boot option. From the desktop I'm trying to perform an Install to Hard Drive. I've read the Install from LiveCD post regarding the creation of a /boot partition and a / root partition. I've tried creating them without the LVM group and with. But every time I appempt to install I get...
An error occurred mounting device proc as /proc: mount failed: (9, None). This is a fatal error and the install cannot continue.

I tried to mount my CD Rom drive and got this response: "mount: can't find cdrom in /etc/fstab or /etc/mtab"
I did see the CD Rom drive briefly after I upgraded from 10.04 to 10.10 but I couldn't access the drive and when I logged back in.

I have been able to plug my iPhone in, and Ubuntu (10.04) has been able to see it immediatly. I was able to browse any pics etc. AND, I had the ability to SSH into it (Places>Connect To Server). In the connect to server dialoge, I clicked on the drop box and had several options including SSH. Now, there's nothing in the dialogue except "Custom Location". So, what happened? 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.

I have just bought new PC (Intel mother board "Intel DP43TF ATX" and Processor "Intel Core 2 Quad Q9550"). and I have installed centos 5.3 32 bit.
NOTE: All cores are enabled in BIOS.
When I issue below command, it shows only one core (not 4 cores): what could be reason!
# cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 23

Here was I get on my screen.
I don't know why this is happened. But before I rebooted, I could not see any content on Windows like update or shut-down (if I tried to install something and it asked for confirmation, that window was blank. Or before I shut down, I had to push enter, since that windows was blank.)
I don't think I installed anything and computer was working just fine before.
I don't want to reinstall everything again.

I have a directory, /root/backup, that I mount and run a bunch of rysnc scripts against to backup my box. I'm running into a very recent problem where when I run this command:
A directory that once looked like this:
Goes to this:
It changes from root to www (another user on my system) and I have no idea why.
When I look at the /mount/procs file, I see this:
So it looks like the uid is correct...
I believe this is what is causing my rsync scripts to fail (they only copy over directories and not the files in those directorys and I get a lot of permissions failed errors)
All of this is run as root in cron jobs
As a note, here is a sample rsync command:

Whenever I plug in my PSPgo via USB, it shows up in Nautilus as:
Code:
The first line is the system's onboard memory, and the second line is my 16 gig memory card. It used to mount as:
Code:
I *cannot* unmount the drive. The computer does not seem to be able to find the mount point to take it off from. When I unmount from Nautilus, it says:
Code:
Error unmounting:
If I just unplug the drive, the entry in /media remains as 1C[glitchy box thing][series of underscores] (see screenshot)
I tried looking at the drive in gparted, and it says:
Code:
Code:
Is my PSPgo becoming corrupt or something? That would be supremely unpleasant. I'd definitely like to avoid that, if at all possible.

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.

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 used unetbootin to create my bootable usb with 10.10 for netbook. I am trying to install ubuntu on my brand new fresh out of the box Asus Eee PC 1018P but the problem is when I hit esc during the boot to get to bios to select boot from usb, the usb doesn't show up as an option. I also tried hitting f2 and making it an option to boot from usb but that doesn't seem to work either.

I've had two students report a problem whereby Ubuntu does not show up as a menu option in Grub. Both systems used Wubi installations of Ubuntu 10.04 Desktop for x86 on Windows XP. In both cases, Ubuntu completed the installation process. Upon reboot, we have the options to choose between Windows XP and Ubuntu. However, once we enter into Grub, only the Windows XP option shows.

Im trying to install GNOME-3 on top of kde and have GNOME DE option show up in kdm. I have SUSE DVD and have set local(OD) repository priority to 80 in order to get most packages from DVD. Inspite of that YaST pulls packages from online repositories, it may be the latest version. I have 8 MbPS dsl but the YaST download speeds are around 500B. How do I change mirrors of repositories. In my opinion this has nothing to do with ipv6, I use ipv6 for openBSD and it get good browsing speeds. Im trying to set kdm4 login manager but it doesnt start after enabling for YaST-/etc/sysconfig.

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?
Code:
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.

Does anybody else have this problem with restretto image viewer that it freezes after enabling the "show thumbnail bar" option? And after that point, it becomes unusable, can't be closed, only by killing, and can't start anymore, it shows only an empty gtk window and freezes again. Even if it is loaded without to show any picture.

I have a Western Digital 2TB HDD on Ubuntu 9.10. This is my secondary HDD which is used only for Storage of media files. I mount it as & when needed only to stream my media content. I have tried many times to use tune2fs to free up the extra space which has been reserved automatically by linux yet although it accepts the commands & doesnt give back any errors, when I run the df- h or du- h commands, linux has still reserved 200GB & I only have 1.8TB to use. This extremely annoying as Im quickly filling it up with about 400GB currently available for me, that could easily be 500GB.
My primary drive is a seperate HDD of 320GB Storage is /dev/sdb1 for which I mount it to a folder called 'media-centre'. Then after mounting, I run the command: tune2fs -m 0 /dev/sdb1 media-centre I takes the command with no problems, I run df -h, & no joy. I have read my books at home as well as google searches & forums. Am I missing something simple here, does this command work only with certain types of HDD's?
I posted on another forum & followed a post that said I should convert from ext3 to ext2 as the journal is the cause, I ran a tune2fs -O ^has_journal etx2 /dev/sdb1 (something like that) & checked /etc/fstab which did not reference my storage HDD.

The HDD is a 500GB internal SATA, The smart claims that the "file system is not clean" but is still green.FSCK ran a few errors and using fsck i copied a new superblock from a backup location, It still won't let me mount and FSCK is still trying to fix a TON of errors. I'm sorry I don't know any of this yet, but I'm concerned that FSCK could be destroying the data on the drive, for example photos and other important things. FSCK is coming with a lot of things to fix, It's gone from trying to fix errors in free blocks of group #1 to over #3000.. Is this safe? Will this work? Can I get rid of whatever caused this problem in the first place?

I have since quite a long time the problem that files using special characters in their filenames are not displayed in various applications. In console or Thunar I have a special "white questionmark in a rhombus" sign for every special character. It is an XFS partition. I have read a few times that this can be solved by using the iocharset=utf8 option in /etc/fstab, but this option is not recognized and the mount inhibited.
I used other options: utf8 as well as nls=utf8, but that was not recognized neither. What option do I need to specify to enable utf8 for XFS ? Samba works. That means I can play an MP3 file in Windows exported from the XFS disk using Samba, although the special character is then shown as "_" in Windows..

I have made a clean install number of times. At the point where you (I always do this) manually select the partition where you want Ubuntu to be installed there is a option where you want the Mount Point. The options are / /boot /home /tmp /usr etc. up to now I have always used / but I'm not sure effect choosing some of the options would be.
