General :: Unable To Automount Ext3 Formated Usb Disk
Jun 14, 2010
I have a NAS from WD that runs some stripped down flavor of linux. The NAS has one USB port at the back which can be used to expand the storage. If I plug in an external disk formated in either NTFS or HFS+ then the system automatically mounts the disk and shares it over samba. If I plug in a disk that is formated in ext3, the disk is recognized but that's about it. It doesn't mount or get shared or anything. I have tried asking WD about this and I have tried asking google. But after two days of searching I am turning here for some more expert advice.
Here is what I've managed to figure out so far.
If I check dmesg before and after plugging in the ext3 usb disk I have found out that these lines are added to the log:
Code:
I have tried googleing those last two lines but I haven't found any info that I can make any sense of.
If I run the command "mount -a" I get the following messages from the shell: "mount: Cannot read /etc/fstab: No such file or directory"
Hover I am able to mount the ext3 disk manually. First I get this info from fdisk
Code:
And then I run these two commands:
Code:
This makes the usb disk visible in the shell, but since this is a NAS, it is kinda useless as long as it doesn't show up in samba.
Since I'm pretty new to linux I don't know what to try next so I'm hoping for some advice as to what I can do to make the ext3 usb disk automount.

OS: Debian unstable 32bit, kernel 2.6.32-2, grub 1.98 from late january 2010 (only have working net-access from work now, so I am grabbing information from memory). EXT3 and EXT4 support is compiled into the kernel along with chipset/scsi/sata support (not as modules), and I have tested to boot ext3 with it before proceeding. Prereq: my old disk started to have too much S.M.A.R.T errors, so I bought another one, put in a USB cabinet, added swap and ext4 partition/filesystem to it, and copied over all data from the old system to the new that was mounted at /dest using the command "find ./ -xdev -print0 | cpio -paV0 /dest". Swiched disks, so I now have the ext4 disk sitting at /dev/sda (partitions: sda1 => ext4, sda2 => swap), and booted into rescue-mode from cdrom, using /dev/sda1 as root with a shell on. After doing this, I performed the following commands:
mount --bind /dev /dest/dev
chroot /dest
modified the /etc/default/grub to instruct the kernel to boot using ext4, ran grub-install --recheck /dev/sda
ran update-grub to modify /boot/grub/grub.cfg (which looks as it should) After doing this, grub finds my partition and mounts it. It however stalls with the message: "warning: unable to open an initial console" and does nothing after this point. I have no ramdisk, but my old kernel booted fine from ext3 (and still does if I copy it to a ext3 partition), and since the ext4 support is compiled into the kernel - should I really need a ramdisk?

I killed Win XP awhile back, but there are a couple games I need to format for Ubuntu to use, using XP to get there.
I have Ubuntu LTR. I formatted disk to install XP. I installed XP. I can't boot into Ubuntu anymore unless from a live CD. From Live CD, I can see my Ubuntu is still there, but from XP, disk manager it shows that space as empty (free). How can I dual boot, now? Please don't tell me I need to reinstall Ubuntu, I may cry. Any help is appreciated and my apologies if my search didn't get me the answers, the other similar problems I saw were in reverse order (Linux onto drive after XP).

I have a 2 TB disk in an external SATA dock, formatted with a single ext3 (Linux) partition, which doesn't show up in the Windows 7 Computer Management->Disk Management utility, even as a raw/blank disk. I've verified that there's nothing wrong with the disk by connecting it to my Linux machine and mounting it, and I've verified that the dock is functioning properly by connecting a different FAT32-formatted disk, which mounts flawlessly as expected.I realize that I can't actually read the ext3 partition without additional software (e.g., Ext3IFS), but why doesn't the disk show up at all? Is there some sort of stupid anti-Linux filter built in? Is there any way to force Windows to recognize the disk, so that I can at the very least use direct block access with it?
Background: I want to clone an identical 2 TB disk onto this one. Due to my hardware layout, it's much easier to have the source disk attached to one machine and the destination disk connected to another, and do the clone over the network (the network is not a bottleneck with switched gigabit ethernet), than it is to hook them both up to one machine.(1) I did this once before when both machines were running Linux, but I've since upgraded the destination machine and decided to switch back to Windows for regular desktop use. I've got Cygwin installed, and have verified that the same basic method (dd + nc) will work, but I can't do anything if Windows doesn't even consider the destination disk to exist.I only have one eSATA port on each machine. Opening them up just to do this clone is a rather large annoyance. Also, since this is my backup disk, I'd like to eventually automate the cloning from the active disk to another one that I regularly swap with a third disk that I store off-site.

I have two USB drives, one with ext3, and the other w/vfat. On my new Fedora 12 installation, GNOME properly automounts the vfat drive on insertion. However, it applies a wrong command to mount the ext3 one. The end result is that the ext3 drive appears in /etc/mtab but, unlike vfat, is inaccessible to non-power user.
The mtab is: /dev/sdb1 /media/918fb656-8efc-43b5-bdfd-0bd8004deeba ext3 rw,nosuid,nodev,uhelper=devkit 0 0
/dev/sdb1 /media/49C6-1901 vfat rw,nosuid,nodev,uhelper=devkit,uid=500,gid=500,sho rtname=mixed,dmask=0077,utf8=1,flush 0 0
Somehow GNOME misses the uid=500,gid=500,shortname=mixed,dmask=0077,utf8=1, flush portion of the mount command when mounting the ext3 drive.

I recently installed Linux to run a few Linux based tools on a disk images I have, and I can't seem to copy the disk image over to my ext3 partition.
The particular distibution I'm using is BackTrack 4 r2, which is Ubuntu based. I can't seem to find specifically which version of Ubuntu is being used. The disk image is 108GB. It is currently located on a NTFS partition on a SATA hard drive connected directly to the computer. The ext3 partition is located on a second SATA hard drive connected to the same computer. It has 200GB total. I do not remember exactly how much free space it had but "df -h" showed a lot more than 108GB. The computer has 4GB of RAM and I gave it 8GB of swap space.
At this point it has been running for more than 12 hours. This is far longer than I would expect it to take had I been copying the file under Windows. How ever I do not have much experience with Linux, so if it's supose to take this long please let me know. I am planning on letting it run until I wake up tomorrow.
"cp -v" hasn't been very verbose at all. The only sign I have that indicates the computer is still trying to do something is the HDD light on my chasis that has stayed lit this whole time.

I need to copy data from a single HD, which used to be part of a Linux RAID 1. I've googled around, but can't find any clue how to mount partitions from this single HD.
Background: The HD comes from a linux based NAS box Synology DS207+. The NAS uses ext3 as filesystem. Both NAS disks are fine, but the other NAS hardware is dead and not worth repairing or replacing.

Running Debian Squeeze, I used gparted to wipe the fat partition on a 8GB USB thumbdrive, and repartitioned it with ext3. Everything goes fine, and gparted and fdisk -l both show the correct partition, but I can't seem to mount it, and automount in gnome fails as well.code...

I am using Wind River Linux- 2.6.27.18-WR3.0bg_standard. The problem is whenever I execute "reboot, ls, cd" and many other commands the OS prompts me an error-
"end request: i/o error, dev sda, sector "(different sector each time)" and
EXT3-fs error (device sda1):ext3_get_inode_loc:unable to read inode block- inode-4088001, block-4097027
I also executed "dmesg", it also showed similar errors. Has the disk gone bad or the kernel is corrupted?

My co-worker install CentOS with /var (ext3) is 1TB:
Code:
I do the following tasks to move sdb1 to VolGroup00:
After that I moved /var back to / folder and reboot but the system hangs at "Starting system logger". Uninstall and re-install sysklogd package don't make any change. What I don't understand is I can start syslogd from command line:

Or run the init script in debug mode:

Dell laptop booting from a USB stick with a CentOS 5.5 minimum installation.
Uncompressing Linux...OK, booting the kernel.
Red Hat nash version 4.2.1.13 starting
sda: assuming drive cache: write through
sda: assuming drive cache: write through
mount: error 6 mounting ext3
mount: error 2 mounting none
switchroot: mount failed: 22
umount /initrd-dev failed: 2
Kernel panic - no syncing: Attempted to kill init!
1. Does minimum installation not drop on a kernel or initrd with ext3 support? I can't imagine that's true, but have to ask.
2. The USB stick is single partition ext3. Maybe there is some limitation specifically related to USB stick booting that requires boot to be FAT16 or FAT32? Except the CentOS 5.5 installer refuses to let me install on either FAT.
3. How can I do the equivalent of lsmod on a linux installation that will not boot? i.e. I have CentOS x86_64 running in VirtualBox, I can plug the USB stick in there, so how do I get information on the USB stick's kernel and initrd if I can't boot from it?
4. Is it possible to rebuild the i386 based initrd on this USB stick, when the computer is not booted from that stick, with a system that's x86_64 based?
System Info:
Dell Latitude i686 Laptop which has run CentOS 5.5 and Fedora 12,13,14 in the past, and boots from Fedora 14 Live CD transferred to a USB stick. So I know USB booting is possible on this machine, and this stick.
The process of creating the stick:
CentOS 5.5 i386 on a USB stick. Old Dell i686 laptop which has previously run CentOS 5.5 installed from DVD, and has successfully booted from this same USB stick holding transferred Fedora 12,13,14 Live CDs. CentOS 5.5 was installed onto the USB drive directly by the CentOS 5.5 DVD installer (running virtualized in VirtualBox 4.02 on Mac OS X 10.6.5.). No errors or complaints during installation.
For whatever reason, the installer did not do some things correctly. First Grub wasn't working correctly, I got that sorted out and have the Grub+CentOS splash screen, it finds vmlinuz and the initrd, and then I get a kernel panic.
Ext3 was built into the kernel and that's why I'm getting this message. I do not know how the installer would have dropped a kernel or initrd during instalation that that don't contain such a basic thing that obviously comes in linux kernel 2.6.18-89 EL.

I have recently bought a Toshiba 1TB external USB disk.
I have formatted it using gparted to ext2 and Debian see's it but gives me an error "unable to mount volume" with some extra stuff about programs shouldn't disconnect shared drives.
I can mount it ok by creating a folder called usbdisk and the mount command "mount -t ext2 /dev/sda1 /home/mike/usbdisk" and it works fine, but I have to do this everytime I start the machine.
Does anyone know what exactly I should put into a setup file to make the machine do this everytime , but only if its there.
As I'm not very clued up on bash scripting , I'm assuming it something along these lines:
How would I add this at boot?? Would I add it to the end of "init.d/rc" ?

I have OpenSuSE 11.0 running on a machine. I want to be able to automount a USB disk but it seems at the moment automounting only works if your logged in to a KDE desktop. That's no use to me as I want the disk to be used by automated processes when available.
How can I set the disk up so that it auto mounts when I plug it in regardless of whether there is an active desktop or console session. It should be able to handle being removed and then reinserted with out a reboot or without having to log on.

I Tarred and GZipped most of the data on one 1Tb partition and stuck the archives on a second 1Tb partition on a separate disk. I then proceeded to format the first partition with NTFS (from Linux.) The only problem is that I completely forgot that I had a CD drive and formatted sdc1 instead of sdd1! I began doing a full NTFS format and after a minute or two I cancelled it and decided to do a quick format. I then realized my mistake. I managed to find a copy of the superblock and began trying to recover the disk. fsck -t ext3 recognized the partition as NTFS but I luckily didn't have fsck.ntfs installed so it didn't touch it. I managed to get it working with fsck.ext3 (with -b,-B and -y) fsck.ext3 didn't mind that it was an NTFS partition.
Roughly how long will this take? It's running from Knoppix within a virtual machine to a USB hard drive which is 100% full. Days? Being that for a few minutes I attempted a full format am I going to end up with a bunch of corrupted archives? If I do end up with file corruption can anyone recommend a way of recovering the data / sorting it out? Is it likely to be just a few old files that are corrupt (It's my understanding that filesystems like to keep files in the same area on the disk to minimize the amount of head travel.) This might just be wishful thinking but as the filesystem fills up will ext3 put the newer files towards the end of the disk? If so then I'm hoping that a full NTFS format starts at the beginning of the disk.

I have an external 300GB (Toshiba) disk which I encrypted (using cryptsetup luksFormat) and then installed an NTFS filesystem on (need to be able to use it in both Linux and Windows - using FreeOTFE). The disk mounts fine in windows and on my Fedora 10 system it automounts.
I can manually mount it on the RHEL5.3 system, and gnome-mount gets as far as recognising that it is encrypted and asking for the key, but it doesn't then mount it - I then have to manually mount the /dev/mapper/luks... device.
Does anyone know how to do this - if it works in Fedora 10 it ought to be possible to get it to work in EL5.3 I'd have thought.

How can I get a LUKS encrypted partition on an external USB device automounted with r/w access for non-privileged users?
Background:
I just reformatted an external USB device with ext4. The only partition is LUKS encrypted. Now, when I plug the device to my computer, KDE notifies me and asks me to enter the LUKS passphrase. Then it mounts the device. Little snag here: Non-privileged users have read-only access.
My user is a member of group plugdev, but not of group disk, as this was discouraged several times, e. g. by Robby Workman. With non-encrypted disks regular users have read/write access, or can change the filemodes accordingly, as far as I recall (currently I have no more non-encrypted disks left to verify it...)

I want to format an USB disk with ext3. If I do this with gparted, it will be formatted, but I cannot write to it. Reading is no problen, at least it shows the lost+found folder. I guess its a problem with access rights. It would be sufficient if user "papa" would have access on one ubuntu karmic machine. But I cannot solve this graphically. The purpose of the operation is to be able to copy my /home directory onto the USB disk as a backup, before I upgrade to the current version of Ubuntu. FAT32 is no option as some files are too long.

I'm fairly new to Ubuntu and I'm running Karmic Koala. I just reformatted an NTFS partition to Ext3, as I no longer need to access is from my windows installation. Now I'm unable to mount it though, and I get the message: Error mounting: mount exited with exit code 1: helper failed with: mount: only root can mount /dev/sda6 on /media/DATA2 (DATA2 being the name of the previous NTFS partition. Now the label is linuxdata)
When I try to mount it using sudo in terminal I get the following message if I use the label DATA2:
NTFS signature is missing.
Failed to mount '/dev/sda6': Ogiltigt argument
The device '/dev/sda6' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
And if I use the label linuxdata: mount: can't find /media/linuxdata in /etc/fstab or /etc/mtab I've tried to search for help, but been unable to find an explanation.

I am student of MCS and working on final project. I am the user of windows xp. I am new in Linux. I am working on a project that titles "Hard disk data Recovery of ext2 and ext3 in linux". In windows, including dos.h and bios.h header files in program of c language I can send interrupt to bios and access most of the devices like parallel port, hard disks etc. But problem is that there is no bios.h and dos.h files in gcc. Now how can I access my hard drive using c program. How can I call int13h interrupt in linux or there is any other function in the linux to access the hard disk. In fact I want to access sectors of my hard disk using c language program. How can I do it?

I have a second hard drive in my desktop and both the main dirve and second drive are 250GB. I use the second drive for backups, both manual and using back in time. The other day I noticed that the second drive was formated in FAT32. If I go to disk utility and look at the drive it says:Usage:FilesystemPartition Type:Linux (0x83)Type:FAT(32-bit version)Is this ok? I thought in Linux it should be Ext4. So far its been working fine for a while now but if I need to move my files and re format it to ext4 and move them back I would rather do it now when there is less data on the drive.

Only noticed this a few days ago & it only affects CD/DVD's, USB drives automount just fine.After doing lots of searching, noticed that a lot of people are having this issue too. Only didn't work out how to resolve this annoying behaviour.When I burn a CD/DVD K3b accepts that I have valid meia & proceeds to burn, when the disc has been burnt out it pops. So I re-insert the disc & no automounting?I have put myself in the 'cdrom' & 'disk' groups, just to ensure it wasn't something I'd not done. It was working fine last time I checked, so don't think it's that.

I placed some new partitions in my hard disk but have been unable to write the correct entry in fstab to get them to automount. I can see them in nautilus and manually mount and use them, but I get failures when I try to add them to fstab, unsure what I am doing wrongI mounted two new partitions, one ext4 and one ntfs formatted partions.The fstab file reads as follows
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc nodev,noexec,nosuid 0 0
/dev/sda5 / ext4 errors=remount-ro 0 1

I have been having problems with filesystem corruption on my eeepc 1000H for a long time now. I have tried using different filesystems, kernels and distributions (arch, slackware) to no effect. I am starting to grow suspicious that this problem lies somewhere else, as I haven't seen anyone else having similar problems in such a variety of scenarios.
I have tried testing my ram using memtest86+, didn't come up with anything after a full run through. I also have tried using e2fsck -c to check for bad blocks, it finds none. I had a go at using smartctl but wasn't really sure what I was doing. I did a long test and it came up with nothing anyway.
This problem is in addition to the problems I've been having with my intel graphics chip and KMS. A lot of the time there are lockups when booting into X, which can only be gotten out of by a hard reset. This is sometimes what causes the original filesystem errors. I've stopped messing around with KMS for now to eliminate this but my current system in unbootable. I'm guessing my disk is wrecked but have as yet seen no definitive proof. Can anyone recommend anything that I should do?
I am currently on ext4 with a custom kernel 2.6.33-rc6 (the stock kernel shipping with slackware does not have the elantech extension for psmouse included). When I was using arch, I was just using the stock kernels.

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.

Code:

Either mount the volume as root, or rebuild NTFS-3G with integrated FUSE support and make it setuid root. Please see more information at [URL] Is there any way that I can mount this drive (which must be ntfs-formatted) without root permissions? I have googled this error and it seems that many other people are having this same problem, but I can't find a real solution. Most people suggest just reformatting the drive.

I am trying to install Fedora 11 in Virtual Box using the Live CD. When I try to format with EXT4 (Default) it says the boot volume cannot be EXT4, when I try EXT3 it says it doesn't match the Live filesystem. This is retarded it won't let me use either. (I don't usually throw around the word retarded, only in rare cases and this is one)
