Ubuntu :: Can't Boot Lucid LTS Anymore - Automount Error For Data Partition; / Is Md0
Apr 15, 2011
My Lucid LTS Ubuntu Studio 64 (amd) won't boot anymore; / and /home each are software raid 0 partitions.
I have a Multimedia partition (also ext 4) which I attempted to chmod with a GUI program (I forget what its called now) to enable all users read/write access. Looks like I inadvertently fstabed that partition to be mounted at boot-time (normally my password was required in order to mount it).
I tried to logging out and back into my OS to see if the partition was now writable but it wasen't; instead a filesystem error was noted. I realised then that my partition was IMPROPERLY labelled and I was in a tired state and didn't remember how to rename it & rebooted to make sure all was ok. But it was not:
An error occured when mounting /media/Ubuntu unknown filesystem type "Multimedia"
Boot: recovering journal
From my generic Ubuntu system on a non raid partition, I finally removed the space in the 'offending' partition: Ubuntu Multimedia to UbuntuMultimedia. And I changed the permissions for it.
But if I try to boot Ubuntu Studio via recovery; booting in low res is unusable, and it gets stuck if I SKIP mounting. So I am left with manual boot or drop to a shell. I will have to use an editor like vi or nano and the command prompt. I know that I likely only have to comment out a line in etc/fstab but I am only familiar with nautilus or gedit for this type of operation. And since this OS is on a raid partition its not 'seen' on the live CD....
I would need someone to offer me clear steps to follow with the non gui editors otherwise I'm in trouble...
I just wanted to use that partition for video editing and now I am locked out of my system!

I can not boot into ubuntu anymore, I have a kernel problem. Is it possible to save the stored data? Maybe with a livecd? I am really tired to solve the kernel problem I will only save my data and then I will install ubuntu again.
i recently deleted a NTFS partition while ubuntu was running and didnt disable the automount and when i tried to restart from what i can see it is trying to mount the partition which does not exist. When booting it says something to the effect of mounting dev/sda5 (which is now ubuntu) NTFS signature incorrect, what file must i change to allow ubuntu to boot because i kind of dont want to reinstall ubuntu and reconfigure it.

I was messing around with the partitions and accidentally y deleted the ubuntu partition! I have Windows 7 as a dual boot but I can't access to that OS anymore. The message that I get is: error: no such partition. grub rescue>
After a new Fedora 12 installation, i cannot automount my Windows partition. My system is setup originally at windows XP ,partitioned, then change to Fedora 10. Change to Fedora 11 through update.System very slow.
I decided to upgrade to fedora 12 by DVD installer, then i have to mount manually to access my back-up, when typing su -c '/sbin/fdisk -l' at terminal, this is the code:
I recently switched from fedora 14 to 15. Today my computer suddenly shut down during an update, as I thought it overheated I decided to clean the cooling system and reapply thermal paste. However, now the system won't boot anymore ("kernel panic - not syncing : VFS: unable to mount root FS on unknown-block").
I would like to either solve this booting problem, or mount the fedora 15 filesystem and recover some files. Whichever is easier.
I have another drive with fedora 14 (antec below) which boots fine:
I have 2 hard drives on mu box 1st one is 500.0 MB ext4 Volume where I have my syste FC 13 and a 2nd one where I put my database files as follows 78.1 GB ext4 Volume usage = filesystem, format ext4
ih file browser, I can see an icon for a 80GB hard drive but whenever I double click I get the following

clicking details

Error mounting: mount exited with exit code 1: helper failed with: mount: wrong fs type, bad option, bad superblock on /dev/sda1, missing codepage or helper program, or other error
when I type

I get

What is very strange is that mysql works fine.In disk utility, it indicates that disk is healthy, but when I click check file system i get
File system check on "data" (Partition 1 of ATA MAXTOR STM380215A) completed File system is NOT clean
I cannot force Ubuntu to open my data DVDs upon their insertion. It is present, but it won't automount. Of course, in /etc/fstab are no indications for removabledevices, but this is correct, I think.
I am trying to install a box here where my /storage partition is about 2.5T.I had setup the partitioning with suse, while testing, and all worked well.Now when trying to install CentOs 5.5 it gives me an error, that my boot partition is on a gpt partition and this machine cannot boot that.Also I don't see the option to create XFS partitions from the installer.Can 5.5 support GPT @ install time?
When a USB device is attached to the laptop 10.04 does not automount the device. i.e. the device, be at an external drive, memory stick or iPod does not display with the correct icon on the desktop.
However, if one looks under Places|Computer there they all are with the correct icons. The devices can then be mounted from there.
This issue seems to be related to these other posts: [URL]
This is really disappointing given that 10.04 was promoted on its iPod friendliness!

My external HD where everything I backed up from my previous install will not mount. It shows up in lsusb, but when I do dmesg:
Code: [20801.408614] usb 1-3: USB disconnect, address 36 [20804.190095] usb 1-3: new high speed USB device using ehci_hcd and address 38 [20804.343675] usb 1-3: string descriptor 0 malformed (err = -61), defaulting to 0x0409 [20804.345100] usb 1-3: configuration #1 chosen from 1 choice
Also of note, my main filesystem is reiserfs, so there isn't a problem of not having reiser installed.
I've been tinkering for over a week to try and get a functioning triple boot + shared data working. i've hit a road block. i'm using reFIt with SnowLeopard/W7/10.10. i can't get into ubuntu

OSX and Windows are fine. but whenever i select linux, it boots directly into windows. i'm hoping i don't need to install GRUB2 to the windows partition as that would defeat the purpose of reFIt (would it not?)
The DVD was created with Nero Express on a Windows XP SP3 system and reads perfectly well there.On CentOS 5.3 (at least) it will not automaount. I can mount and dismount the DVD manually. I can access the DVD with K3b.CDs mount just fine and come up as an Icon on the Gnome desktop. This is what I would like to happen for the DVD as well. The CD mounts at /media, which puzzles me. I read through a great deal on the web, but have found nothing that addresses the specfic probem. I know the Gnome Volume Manager and HAL are gone. I tried changing the autofs settings by adding the following line to the /etc/auto.misc file
dvd-fstype=auto,nosuid,nodev :/dev/dvdrw
to join the line for the CD, and then rebooting, but without success.
I'm probably missing something noobishly obvious here. I recently did a fresh Lucid install on my main desktop box, which had previously been running Karmic. With Lucid I can no longer use fstab in my laptops to automatically mount the desktop's shared media drive. Using the mount command works fine. One laptop is running Karmic, the other is running Hardy.This is the line in fstab on both laptops:
Code: //192.168.0.123/multimedia /media/multimedia cifs username=x,password=y 0 0 This is unchanged since the desktop was running Karmic, where auto-mounting from the lappys worked just
I'm running dual boot with Vista and Ubuntu Lucid Lynx. for few days i was running Ubuntu only, downloaded some files and created some directories. few minutes ago, i switched to Vista to see something and i wanted to burn some of the files i downloaded using Ubuntu but couldn't find those folders.
i thought maybe its related to different file system or something so i switched back to Ubuntu and surprise! my folders are not there, instead i got a file, of unknown type with the same name as the folder had! in another folder case it's was an image (some print screen of my browser screen - Mozilla) and again with the name of what was the folder! first - what the hall had happened? second - can i recover my data somehow?
Running 11.3, KDE 4.4.Have searched all over hell on the Internet, no solution found.When I insert a data CD or data DVD created with K3B sometime in the past, the Device Notifier pops up with NO description of the device plugged in. After it goes away, I can hover over it and it will say the name of the device which is the volume label of the backup CD or DVD.However, when I go to Konqueror, there is nothing showing under /media.If I run Dolphin and view the Places menu, the CD shows up there, I can double click on it and open it.
In Device Notifier Settings, under Removable Devices, I have Enable Automatic Mounting of Removable Media checked, as well as Only Automatically Mount Removable Media That Has Been Manually Mounted Before, and Automatically Mount Removable Media When Attached.The CD inserted does appear in the Attached Devices list in the Removable Devices.If I put a CD in and check Konqueror, it does not show under /Media. If I then load Dolphin, it shows in the Places menu and under /Media. THEN if I go back to Konqueror, without doing anything else, it will THEN show up in /Media.If I then close Dolphin and eject the CD/DVD, it disappears from /Media as expected. If I then reinsert the DVD into the drive, without opening Dolphin, it will re-appear in Konqueror under /Media as it should.Why isn't this working properly in Konqueror? It's a massive annoyance.There is zero documentation for Device Notifier available and especially for setting up Device Settings.At one point, I thought that "Only Automatically Mount Removable Media That Has Been Manually Mounted Before" might be the problem, so I unchecked it. But it does appear to be the problem.
I don't know why KDE 4.4 can't do what KDE 3.5 did - just automatically mount CDs/DVDs and USB devices without a lot of rigmarole and undocumented settings and with a simple selection of what you want to do with the mounted device (which I usually just ignore, select nothing, and go look at the inserted device with Konqueror). This was simple and worked. Now it's a nightmare and I see from browsing the forums that a lot of people have had problems with automounting.
A few days ago, after I made some changes on my lucid system, hibernation is not possible any more, that is, if I choose hibernation, everything seems to go fine but at the next boot, the image is not read by the kernel and normal boot happens. Hibernation is very important to me, what can I do go get it back ?
Thunderbird won't start in Lucid 10.04 It used to work, but stopped working (an update perhaps) Running from the menu just gives a tiny window, which when expanded is blank Running thunderbird from the from the command line crashes as follows:
Code: peter@trinity:~$ /usr/lib/thunderbird-3.0.5/thunderbird-bin /usr/lib/thunderbird-3.0.5/thunderbird-bin: error while loading shared libraries: libmozjs.so: cannot open shared object file: No such file or directory Looking for the missing library:
I am installing a custom 8.04 live disk (basically, a mirror of my whole system with user data intact, sans all non-OS files) from a USB key with remastersys for the .iso creation, and UNetbootin for the bootable USB on a brand new 120GB PATA WD HDD. Both do nicely so far, so I have a working livedisk to use until I need to install Ubuntu to the drive.
I had a pure linux box, but I need to add XP with dual booting now- I have to use Autodesk Inventor 2010 software for my college class on my laptop, so I don't drive 30 miles to use the 1 computer lab equipped with that software. I'm not new to Linux, but I am new to more in-depth partitioning. I've taken the lead and looked into things- read this good guide, among others:
HTML Code: http://www.psychocats.net/ubuntu/partitioning and noticed that there is a way to more deftly use partitions so that personal files can be shared access and write between Windows and Linux partitions- with this: HTML Code: http://www.fs-driver.org/ Ubuntu is still my main OS, but being able to access all my media/data files between the 2 systems would be nice. Problem is, until now, I've put everything on a single partition because I didn't know better. Now I do, but am a bit confused with all the guides as to what's most efficient, especially in my case where full RAM speed is crucial to running a single program.
Here's what I know I need to do: 1. The Windows XP install I know needs from 20-30GB for Inventor 2010 LT to work well. I don't need anything else in XP spacewise- it's just being added for Inventor. 2. I'd like to create a separate /home partition for Ubuntu this time to save my user data, making future upgrades much more painless (I will be getting Lucid soon). How that works when upgrading, though, I don't know yet..
3. I'd like both OSes to share all my personal files (docs, pics, music, Inventor design files) if it is an efficient choice that works without problems.
4. Finally, because 2GB is minimum for Inventor to run decently, I need to maximize the speed of my RAM for it- from my reading, these so-called "swap" partitions can somehow be added for buffering this- people seem to sugguest the swap be half the size of the RAM for fastest speed, and some say add separate /usr or other partitions. I'm not clear on what would be most efficient for me.
I have limited HDD space- because of my laptop's BIOS, this single 120GB drive is the biggest I can get on my laptop, so efficient partitioning would make a huge difference for me. Before this, a 60GB HDD was in this. I'd like to see some added space for my data storage, but still keep things as fast as possible for Inventor when I use it, and Ubuntu.
I'd like the final layout to have a Windows partition (will start out as XP and will become Win7 when I can afford yet another copy), a partition for Ubuntu, and a shared Data partition that I can use for all my files between both OSs. I think this should be fairly straight forward with Linux on a Primary partition with / and swap. Only thing is, from what I've read (and yes I know this is a bit old school) it might be a good idea to put in a /Home partition so that I can reinstall new upgrades and maintain settings. But I don't want to max out my 4 primary partitions so I can use a 4th partition as a kind of sandbox for OS testing without using VirtualBox all the time.
This leaves me in need of some advice, I've never used Fdisk and I was planning on just using the Ubuntu installer to do all of this, but I don't know if I can create /Home as a logical partition in the main Ubuntu partition and still have the benefit of being able to reformat /root without losing /Home. I might have just confused myself, because no matter how many guides and How Tos I read I still don't really get extended partitions, I understand logical vs. primary but extended is...confusing. I need the Ubuntu partition to be bootable, so it needs to be a primary partition...I think. Unless I can have: /boot, /, swap, and /Home...
Also, if Ubuntu can read NTFS, and Win7 can read Ext3, what should a do with /Data? Or should I just go with FAT32 and be done with it. (It's a big HDD btw, 640 GB, so /Data will be fairly large)
In Lucid I cannot get CPU scaling to work anymore, in previous Ubuntu releases this was not a problem with the same hardware (AMD Phenom 9500 Quad). I used to load module 'powernow-k8' and 'powernowd' to make it work, but it seems 'powernow-k8' is not available in Lucid. Anyone who has cpu scaling working in Lucid?
In running Update Manager in 10.04 I get the following error message; Could not download the upgrades The upgrade is now aborted. Please check your Internet connection or installation media and try again. All files downloaded so far are kept. Failed to fetch http://us.archive.ubuntu.com/ubuntu/...uild2_i386.deb Size mismatch Also, I can't boot to XP anymore.
After upgrading to 10.04 from 9.10 Win7 wouldn't startup any more. So I tried this HowTo: [URL] to restore Grub2. But now each time I boot up I get this two lines: error file not found grub rescue> I have NO idea what to do.
When I plug in a USB in Lucid, it gets mounted at /media/usb0 , etc. I'd like it to mount as /media/<volumelabel>. I know HAL is gone and things have changed, but I'd like to still have the USB mounted at /media/<volumelabel> as it used to, as I got scripts that use those mount points.
I switched to the linux-image-rt kernel a while back, and decided yesterday to switch back to linux-image-generic. Unfortunately, I couldn't remember how to do this properly, so I just uninstalled all of the linux-rt related packages and then changed the /vmlinuz and /initrd.img symbolic links back to what they used to be and rebooted. So now the machine gets stuck in a memtest whenever I boot from the HD. I'm having trouble figuring out how to fix things from a rescue CD. If I try chroot /mnt/hd (where my old system was), and then update-grub, for example, I get: /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?). So, basically I'm completely lost, but also sure that a working system isn't more than a few simple commands away. Can anyone throw me a bone?
I know how to automount ntfs, what I don't know is how to automount a 2nd ext4 partition. I know I can use code...
What am I doing wrong? Also how can I read and write to and form the root of the partition with out opening it as root? This is not the partition I have ubuntu installed on, this is a 2nd partition.
