Ubuntu :: Ext4 Partitions Not Mounting Either Automatically Or Manually?

Oct 21, 2010

I have various drives and partitions that I have been mounting through fstab, but sometimes I had to do it manually, but now, I can't get them to mount at all. At first I thought it might be a disk failure, but booting to a Live CD shows all the drives working fine. when the entries are added into fstab, $mount -l shows them as mounted to their relevant mount points, but the data does't show in either terminal or dolphin?

Typing $umount /dev/drive always returns /dev/drive not mounted.

When I comment out the entries in fstab and reboot and try a manual mount, I always get /dev/drive already mounted or /mount/point busy. $mount -l does not show any mount entry points for the drive. My /home/user partition is now full as I can't save data on the other drives, so I don't know if this is an issue. Also I use a mixture of encrypted partitions and non encrypted partitions, but this wasn't an issue before. Checking some of the logs didn't show any errors. The problem seemed to start when gdd was saving data to a partition mount point I thought was mounted but wasn't. I have since removed that data and even created a new mount point.

Ubuntu :: Mounting Ext4 Drives/partitions In 6.06?

Apr 5, 2010

I just recently found an iso for 6.06 and installed it on an old pc of mine that already had 8.04 and crunchbang on it. crunchbang is on an ext4 formatted partition.

When I setup 6.06, it asked me what i wanted to mount my drives as, so i told it to mount the ext4 system as hda1.

whenever 6.06 boots, it tries to mount hda1 but can't because it doesn't recognize ext4.

What I am asking is this: is there a deb or a package out there I can install to make 6.06 recognize ext4? if not, how can i make it so that 6.06 does not want to mount hda1?

I can get past the initial error message and into the desktop, so 6.06 does work.

Ubuntu :: Automatically Mounting Encrypted Partitions ?

Nov 24, 2010

I've created some encrypted partitions using Disk Utility, and would like them to be automatically mounted when Ubuntu starts up. Is there a guide to this anywhere?

I've gathered that it involves /etc/crypttab and possibly /etc/init.d/cryptdisks, but haven't had much success so far.

Ideally, some of the partitions would mount early in the boot process, while some of them can mount after I've logged in.

Ubuntu :: Lucid Automatically Mounting Windows Partitions?

May 16, 2010

Fairly new to Ubuntu (started with Karmic), now dualbooting Lucid and Windows 7. Lucid is automatically mounting my NTSC partitions, which is pretty convenient since I store all my media there, but I recently deleted one of the partitions and just extended the other one. Now Lucid is still trying to automatically mount the partition that no longer exists and giving me an error message every time I boot up. Not really a big deal, just a minor annoyance, but I'm wondering what I do to make it realize the partition is gone.

CentOS 5 :: Manually Mounting Partitions In "rescue Mode"?

Aug 2, 2010

give me the sequence for manually mounting devices in "rescue mode" ? When I try "linux rescue" from the install disk, it eventually fails to mount my partitions with a generalized failure message, which tells me nothing. I then try mounting them myself on /mnt/sysimage. I have separate root, boot, and home partititions. Is the sequence:

Mount root partition at /mnt/sysimage
chroot /mnt/sysimage
Mount boot partition at /boot
Mount home partition at /home

What about tmpfs, devpts, sysfs ? Do they need to be manually mounted also ? The 'mount' command does not show them as mounted after I do my chroot.

Ubuntu :: Install By Manually Specifying The Partitions?

Dec 19, 2010

how to partition. I was getting sick of having to backup my data every time I had to reinstall Ubuntu, so someone recommend that I partition my hard drive so that I could store all my personal files ( documents, music, and vidoes ) onto the seperate partition. However I don't know how to do this. Furthermore when a new version of Ubuntu is release I always pick the install on the entire hard drive so the partition i installed would end up being deleted. How do you install Ubuntu by manually specifying the partitions.

Ubuntu :: Have To Keep On Manually Mounting Second Hard Drive?

Aug 2, 2010

I added a second internal hard drive to my system.It took a while to figure out how to mount it, and I thought all my problems were over.I want to use this for storage for Transmission since this would keep all the files independent of my other hard drive.One thing that I noticed is that when I restart my computer it doesn't automatically mount the drive (Transmission gives me an error message saying it's not able to access the drive).So I remounted it, and noticed that it restarts all my torrents.One thing that I noticed is that Transmission keeps the .torrent files in /tmp and IIRC there is an option to move them wherever you want to in Deluge (I don't know if this will help anything or not).I don't like Deluge, but if it's somehow easier.

So how can I retain my settings prior to restarting and make this permanent?I do like to turn my computer off from time to time, and I am quad booting with other distros that I like testing out.

Ubuntu :: Ext4 Partitions Mount As Read-only?

Jan 9, 2010

I have 4 partitions. One is Ext4 for Karmic, one is NTFS for WinXP, and the other two are Ext4 where I keep all my stuff.When I boot into Karmic and open Nautilus, none of the last three are auto mounted. When I click on one of them, instead of a window popping out asking me for a sudo password, I get a message as shown below.f I try to mount via sudo in terminal it works, but the files for me are then all read-only. Again, if I open Nautilus as root, all works fine.What I want is the following:- for all 3 partitions to automount on startup;- for all 3 partitions to be owned by me and not by root.I tried editing /etc/fstab, but to no avail. Neither did running "chown" help.

/etc/fstab:
# /etc/fstab: static file system information.

Ubuntu :: Fstab Not Mounting Cifs Manually Call Mount -a?

Apr 30, 2010

I have the following line in my fstab:

Code:
//192.168.0.242/websites /mnt/supercube cifs rw,user=XXX,pass=XXX,iocharset=utf8,file_mode=0777,file_mode=0777,dir_mode=0777,uid=XXX 0 0
But it doesn't auto mount with everything and disconnects whenever I suspend my computer. The only way to get it to mount is with
Code: sudo mount -a and it mounts fine with no error.

Did lucid change the way it uses fstab or something? Obviously writing mount -a isn't a huge concern, but it kind of destroys the point of putting it in my fstab.

Debian :: Looking At Ext4 Partitions From Ms-windows

Dec 8, 2010

I recently downloaded and installed and updated Debian squeeze. Its a dual-boot machine and the migration process is going to take its own time. In the interim, I want to look at the ext4 partitions through windows. I know/knew about ext2ifs fs-driver.org but somehow I'm not able to view the ext4 partitions even though they show up in Control Panel as ext2ifs drives.

If you guys know of any other softwares which can do the same work or better please lemme know. I also tried something called ext2explore but that one crashes all the time around. Lastly, does somebody know which is the best way to be in the know of Squeeze development and the milestones within it.

Ubuntu :: Mounting EXT4 Drives - Unknown Filesystem Error

Mar 6, 2010

I need to examine a hard drive that came from another system running Ubunut Server (not sure what version). I know the drive has LVM on it, so as far as I understand that means the drive will be treated as EXT4 for mounting. I can't boot from the actual disk, but I have used a IDE to USB connector to make a binary copy of the drive, which I've mounted as a loopback device. However, when I try to mount the loopback device properly, I get this:

root@~je:/# mount -o ro -t ext4 /dev/loop0 /mnt
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

I tried using -t ext4dev too, but that just gives an unknown filesystem error. The file I've got mounting in /dev/loop0 is a .dd file, created by imaging the drive using dcfldd on the server drive while it was mounted (as /dev/sdb). System I'm working on is running Ubuntu 9.10. All I need is to be able to mount the server drive so I can traverse the file directories, there's a few things I need to check on it. If needed I can dispense with the whole loopback setup and just directly connect the server hard drive again using the IDE to USB cable, but I'd rather not do that; it's imperative that the drive doesn't get altered, or at least as little as possible.

Ubuntu Installation :: Erasing The Entire Disk Or Specifying The Partitions Manually

Jan 28, 2010

I am trying to install ubuntu 9.10 alongside windows on my laptop's harddrive. When I was going through the procedure it gave me the option of a guided partition of my harddrive... however there was an error. At this stage I unplugged my external harddrive because it's sometimess a bit dodgy and restarted the installation process. However everytime since that I have tried to install, it only gives me the option of erasing the entire disk or specifying the partitions manually

Ubuntu Installation :: Manually Setting Partitions And Mount Points?

If during install, I want to create another partition to keep the OS separate from installed programs and such, to be able to do a clean install every 6 months and not loose everything (or anything) I have done prior.

OpenSUSE Install :: Ext4 - Mounting Point When Partitioning?

Mar 18, 2011

I have a very simple question I am creating a new partition for storing files, installers, documents, etc, I am going to make it ext4, now my question is, do I have to specify a mounting point?? I would not like to do that, but if I do not specify a mounting point, will I be able to access that partition? So in what cases you specify mounting point and when you do not specify mounting point?

Networking :: Mounting XP Network Drive On Machine Works Manually But Not On Boot Up?

Dec 13, 2008

I know this has been covered in many threads before, but I'm stuck not finding my exact situation or an answer. I'm a newbie using a Debian Linux machine as the client and Windows XP machine as the server. I have successfully mounted the XP Network drive on the Linux machine using commands from the root terminal:

mount -t smbfs -o username="Windows Username",password=windowspassword //XPcomputername/folder /mountpoint/

However when I put the command in the ect/fstab file as suggested in several posts, I don't get any result on boot up. I.e. I can't get the network drive to mount on start up, I always have to manually mount it from the root terminal.

OpenSUSE Install :: Mounting Or Checking A Partial Ext4 File System?

Sep 3, 2011

If you have a contiguous partial piece of an ext4 file system (assuming it's perfectly clean), starting from the beginning of the partition, is there any way to check it, or to mount it to get the files whose parents, inodes and data are all completely contained inside?

Have (or maybe had) a very large 11TB RAID 6 array, filled with a single large ext4 partition. Something strange happened when a single drive failed and the array ended up failing 13 out of the 11 drives. I had trouble getting the array restarted, and got to the point where I exhausted all of the options I considered completely safe. I considered a few things that may have worked, but mdadm doesn't seem to have a definite "do not change anything" option. So I decided the only way to be absolutely safe would be to clone the disks before proceeding - then I realized how much time that would take and sent the drives off to a recovery service so they could image them and check it out.

Before doing so, I copied the first 2GB from each disk. I XORd the images from the working drives to reconstruct the data chunks that were on the failed disk, manually assembled the chunks, and am very confident that I have 22GB of "correct" data in a single file. The parity and Q syndromes all matched (with RAID 6 you can still check with only 1 missing device). I've learned the fine details of ext4 from [URL], and have looked at lots of raw data from the reconstructed partition, and it all looks good. The recovery company says that they're not finding many inodes, but I found a lot of them, exactly where they're supposed to be. I tried to mount and e2fsk, but both processes seem to be extremely unhappy that the device size doesn't match the size implied by the file system geometry.

I considered hacking the superblock to manually reduce the size, but I figure that wouldn't work because there would then be more group descriptor blocks than it would expect after the superblocks. I might try doing that and compensating by incrementing the "reserve block count" to compensate. Alternatively, if there is some way to make the file appear to be the expected size with nothing but zeroes after the end of the actual data, maybe I could mount it and not get any errors until I cause the kernel to read past the true end of the file.

Fedora :: Boot Can't Access Ext4 Partitions On LVM Logical Volumes On RAID Array?

Feb 8, 2011

i have a fedora 11 server which can't access the ext4 partitions on lvm logical volumes on a raid array during boot-up. the problem manifested itself after a failed preupgrade to fedora 12; however, i think the attempt at upgrading to fc12 might not have anything to do with the problem, since i last rebooted the server over 250 days ago (sometime soon after the last fedora 11 kernel update). prior to the last reboot, i had successfully rebooted many times (usually after kernel updates) without any problems. i'm pretty sure the fc12 upgrade attempt didn't touch any of the existing files, since it hung on the dependency checking of the fc12 packages. when i try to reboot into my existing fedora 11 installation, though, i get the following screen: (click for full size) a description of the server filesystem (partitions may be different sizes now due to the growing of logical volumes):

Code:

- 250GB system drive
250MB/dev/sdh1/bootext3
lvm partition rest of driveVolGroup_System
10240VolGroup_System-LogVol_root/ext4

[code]....

except he's talking about fake raid and dmraid, whereas my raid is linux software raid using mdadm. this machine is a headless server which acts as my home file, mail, and web server. it also runs mythtv with four hd tuners. i connect remotely to the server using nx or vnc to run applications directly on the server. i also run an xp professional desktop in a qemu virtual machine on the server for times when i need to use windows. so needless to say, it's a major inconvenience to have the machine down.

Ubuntu :: Mounting Partitions - Get NFTS Configuration To Run

Nov 22, 2010

This is my first time using Ubuntu (though I've been interested in it for about a year). I decided to dual-boot my Acer AspireOne netbook running Windows 7 starter with Ubuntu 10.10 Netbook version. I am in the process of looking through all of the information in terms of getting use to the system, but right now I am trying to figure out how to access my files on the Windows half of the computer. I've been following the instructions here: [URL] but I am unable to get NFTS configuration to run, so I moved onto PySDM which appeared to work just fine except now when I boot up it gives me the error: "Unable to mount media/sda3" Press S to skip mounting process or M for manual recovery

Since I am still very much a newbie when it comes to terminal commands, I stayed away from the manual recovery and pressing S just puts me back into the welcome screen so I can log in. I've been searching the forums and I can't find much on it. Maybe I am missing a really important factor here? Also, in some version of the instructions, the other partitions are supposed to become viewable once mounted. I went into looking through the files using PySDM, but what I saw was mostly greyed out files...
