Slackware :: Kernel Tries To Mount Wrong FS Type?
Aug 13, 2010
I just installed Slackware 13.1 x86 on a new laptop (you probably remember me from my audio post). I am having one other issue. My root file system is formatted as EXT4. When my computer boots, it tries to mount it as EXT3 then EXT2, fails both types and then tries EXT4. Here are the messages.
Code:
EXT3-fs (sda2): error: couldn't mount because of unsupported optional features (240)
EXT2-fs (sda2): error: couldn't mount because of unsupported optional features (240)
EXT4-fs (sda2): mounted filesystem with ordered data mode
So, eventually / is mounted correctly, but I think this is slowing down my boot time. Does anyone know how to fix this.

A colleague had troubles with a DVD that contains valuable data, no further backup available. The DVD won't run and I am trying to fix it. Have been playing around on Mac, Windows and Linux successively.
On Mac
Mac shows this message in Toast Titanium 10:
but Finder keeps telling it is an empty disc, no way to get to the files.
On Windows
Windows 7 in VMWare is not of any help.
On Linux
Just installed Ubuntu 11.04 (in VMWare) and did some checks using info on this forum. When trying to mount the disc, this is the error message. Then I used fdisk on the volume (/dev/sr0) and tried fsck. I downloaded UDFTools but cannot find any repair option like udffsck as described in this thread by the last author.
I am running out of inspiration... there are clearly data on the disc, which can be seen by just looking at its surface, but also the info on Mac. However, there might be some bad sector size in the partition table which renders it unreadable. How to recover these data?

I've just made the switch from Ubuntu to Debian Squeeze and am having trouble connecting external media (be it a USB stick or an ext HD). The error I am getting when I connect anything via usb is the following:
Error mounting: mount exited with exit code 1: helper failed with: mount: wrong fs type, bad option, bad superblock on /dev/sdc1, missing codepage or helper program, or other error.

I have been trying to mount an NFS share from my REHL server for over an hour, and Google was not able to help me. when I use the command:
mount -t nfs server3:/programs /programs
I get the folowing error :
mount: wrong fs type, bad option, bad superblock on server3:/programs,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount.<type> helper program)
In some cases useful info is found in syslog - try
dmesg | tail or so

I am writing as yesterday, my fourth hard drive within 2 years crashed. Is that normal? One was crashing 2 years ago, one in winter 2009 and 2 just within 2 weeks. What can be the reason for so many crashes? I heard maybe the power supply? How can I find out if that's broken? The voltages at least in BIOS seem normal. The SATA controller? How do I know if its broken? Can I just but one PCI-E card with SATA adapters? Is it the motherboard? Theres not much more in my computer... As well, its wired that my good-old 160 GB drive never crashed, only constantly the bigger ones. Here some typical error code from mount and dmesg:
Code: mount: wrong fs type, bad option, bad superblock on /dev/sdb2, missing codepage or helper program, or other error
ata2.00: status: { DRDY ERR }
ata2.00: error: { UNC }

I am trying to make a copy of the SD card that my TS-7800 SBC boots from. When I plug the SD into my opensuse pc I get this error. Error mounting: mount exited with exit code 32: mount: wrong fs type, bad option, bad superblock on /dev/sdb4, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so There are four partitions on this card and I can only access one of them.
dmesg | tail gives me this
[894.422497] EXT2-fs warning: mounting unchecked fs, running e2fsck is recommended
when I do e2fsck -p /dev/sdb4 I get
e2fsck: Bad magic number in super-block while trying to open /dev/sdb4 /dev/sdb4: The superblock could not be read or does not describe a correct ext2 file system. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 <device> I was hoping I could just plug in both cards and do this dd if=/dev/sdb of=/dev/sdc to copy everything and have a back up SD card.

I switched today to slackware-current on one of my desktops to play with it and ran directly into a problem.
Since ages my lilo.conf has two entries for slackware. One for runlevel 3 and one for runlevel 4.
Code:
Since the upgrade this is no more possible because I get a kernel panic as soon as udevadm trigger is called. The stack says something about an unknown boot option. Because that i removed the append lines from my lilo.conf and i was able to boot the system. The crash happens when udev is called from within the ramdisk and afterwards. I tried both.
My question is now. Is this a bug in udev or expected? I have this setup since at least 5 years and had never problems with that. What do I have to do to be able to select the runlevel at boot time?

I have been dual booting "Windoz" (hda1) and slackware 11 (RTAI - hda 5) old system. The problem happen after I installed slackware 13(sda8) on the same hard drive. I was able to mount my old slack11 (now (sda5)) to slack13 to read. So I wanted to boot to slack11.
MY Lilo on slack 13:
Now when I boot to Slackware11 I get:
VFS:
How can I boot a old "hda" image on "sda" system. With a floppy I can go back to Slackware11.

Just upgraded from 9.10 to 10.04 and cannot mount one of my partitions. It is encrypted / decrypted in the following fashion:
Code:
# dd if=/dev/random bs=4k count=1 | gpg -a --cipher-algo AES256 -c - > /mnt/usb/keys/fs.gpg
# gpg -q -o - /mnt/usb/keys/fs.gpg | cryptsetup -v -h sha512 -c aes-xts-plain -s 512 create crypto /dev/md1
# mkfs.ext4 /dev/mapper/crypto
# mount /dev/mapper/crypto /crypto
It has been this way for a long time, survived several release upgrades. Now when I decrypt it, I have to use gpg in one command to decrypt the key to a file, then use cat in a second command to pipe to cryptsetup, as such:
Code:
# gpg -q /mnt/usb/keys/fs.gpg
# cat /mnt/usb/keys/fs | cryptsetup -v -h sha512 -c aes-xts-plain -s 512 create crypto /dev/md1
However, I can no longer mount the device:
Code:
# mount /dev/mapper/crypto /store/
mount: you must specify the filesystem type
This is how it's always been mounted. Well I know it's ext4, so I supplied that and was greeted with:
Code:
# mount -t ext4 /dev/mapper/crypto /store/
mount: wrong fs type, bad option, bad superblock on /dev/mapper/crypto, missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
The only item in dmesg is:
Code:
[78.212761] EXT4-fs (dm-0): VFS: Can't find ext4 filesystem

I cannot for the life of me get my HD working again. I tried following all the various remedies I could find but to no avail.
Code:
ubuntu@ubuntu:~$ sudo e2fsck -f /dev/sda1
e2fsck 1.41.4 (27-Jan-2009)
e2fsck: Attempt to read block from filesystem resulted in short read while trying to open /dev/sda1
Could this be a zero-length partition?
Code:
ubuntu@ubuntu:~$ sudo dumpe2fs -f /dev/sda1 | grep -i superblock
dumpe2fs 1.41.4 (27-Jan-2009)
dumpe2fs: Attempt to read block from filesystem resulted in short read while trying to open /dev/sda1
Couldn't find valid filesystem superblock.
It goes on and one like this. I'm stuck using the LiveCD for now (Jaunty) so I have some limitations.

I have been using truecrypt to mount a partition on my computer for a few months now. Yesterday I tried to access it and it failed, with the following error:" mount: you must specify the filesystem type "
When creating the partition, the filesystem type was set to ext2. Apart from yesterday, I have not accessed this partition for a number of days now, and have done nothing to the operating in system in the ways of changing settings and such for a good week.

I made the unfortunate mistake of doing this (sudo rm -r /bin) instead of (sudo rm -r bin) in the folder I was in..I'm trying to copy my data over from my Karmic system using mount, but I'm unable to mount. When I try to mount I get errors of an wrong fs type..
I've done fdisk -l & I get this:
/dev/sda1 * 1 37599 302013936 83 Linux
What the heck filesystem is Linux? Is that like ext3 or something? I don't know. Here is what I'm trying to run:
mount -t ??? /dev/sda1 /media/disk -o force
Also, besides that. If there a way I can fix my OS without having to do a reinstall? Or at least is there a way can backup my files? I have a 1tb external so that's not the issue.

im a rookie at configuring linux and i have problem booting slackware 13.1 just installed. i get a message similar to this Kernel panic - not syncing: VFS: Unable to mount root fs on unknown- block(8,4) i got this one from another user who has a similar problem, they say i should fix lilo.conf and it actually was pointing to a wrong partition so i fixed it. i also fixed /etc/fstab to make it point to the right partition /dev/sda3. but after fixing the files, it still wants to load something in /dev/sda4, i dont know why so what should i do next, please explain with commands and not just words. edit this is my lilo.conf
# LILO configuration file
# generated by 'liloconfig'
#
# Start LILO global section
# Append any additional kernel parameters:
append=" vt.default_utf8=0"
boot = /dev/sda3

I have a system running openSUSE 11.2 with Desktop and XEN kernel, as well as Windows 7 (not by choice though...). I have noticed a strange time issue, with Windows 7 and the desktop kernel the time is correct (like for example now: 1:32 PM) but in the XEN kernel it is ahead several hours (6:32 PM). If it was an issue between openSUSE and windows then I would think that it is a problem with the system clock but I don't know what would cause a time issue between kernels like that.

I've been running arch linux, with my clock set to UTC with no problem. Recently I installed slackware on a different partition. During the setup I chose to set my clock to 'local time' instead of UTC by accident. Now in slackware my clock shows the wrong time. Also in arch it shows the same wrong time.
I booted back into slackware and ran pkgtool to enter the setup again, and changed my time to UTC. But this makes no difference. My clock is still wrong in both slackware and arch. Do I need to reboot after changing my clock settings in slackware before it takes effect? how the clock or the setup works.

I have a x64 OpenSUSE server with two hard drivers installed. The first one is used for the / and /home partitions and the other is for backups. Ironically enough it is the backup hard drive I am having trouble with. I was having trouble writting to the drive and unmounted it to preform a fchsk, however now when ever I try to mount it I get the following error:
mount: wrong fs type, bad option, bad superblock on /dev/sda1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
Does anyone know who I can repair the drive and retrive data?

I tried to post this then couldn't find it anywhere, so I will try again. I am wondering if there is a way to determine what file system type was put on a volume when the file system was made? I have a MD0 device that wouldn't mount. I was receiving "wrong file system type" messages.
I tried df but this only works with mounted file systems correct? I am looking for a command to run on a drive/volume that is not mounted so I can figure out what file system is on it.
This time I was able to: mount /dev/md0 /mnt/storage without and entry in the fstab file. I then just entered mount and it displayed the file system as jfs.
Is there another way to determine the file system type?

I am having a dual boot system vista/ubuntu 9.04. Till recently whenever I wanted to access my vista partition I had to type in the administrative password. However, strangely, for last few days whenever I access the vista partition I don't need to type the password. The partition is just mounted and I can access the files. I would like to know the reasons and if possible to get back the previous situation (needing password to access the vista partition).

When I installed fedora 11 the other day using the live CD it installed the i586 kernel and not the i686, despite the fact that smolt seems to know that that the hardware is i686 (well, actually it's x86, but I'm not going to argue because I forgot to get that one...). Why would it install the i586 one though? (uname -r 2.6.29.6-213.fc11.i586) But more importantly, are there any specific issues which this version can cause that I should be aware of? I can't really be bothered to change it at the moment if there is no real issue with it but I'm not too sure what difference it makes? Is it slower? It seems to know that I have a quad-core processor and seems to use them fine.

Sometimes when I plug in a USB flash drive, it is mounted to /dev/usb0 instead of /dev/drivename. This poses a problem for me because I have applications that depend on files I keep on flash drives, and having to frequently change the file paths is difficult. I haven't been able to find anything on this topic with a cursory search on Google or through the Debian reference. Heck, I don't even know what /dev/usb0 is (though I would like to learn, in the interest of being less of a noob). This is happening on a Squeeze system running Gnome, so I believe nautilus is what's responsible for auto-mounting my flash drives.
Beyond that, I don't know what other information I should provide; if you need to know something else, ask me (and perhaps tell me how to access that information). Someone on IRC suggested that I didn't have my drives set to mount in /dev/, but I have no idea how I would go about fixing that. If there's a configuration file that deals with this sort of thing, chances are I haven't touched it since installing this system. Debian installer sees usb drive as cd drive, so it adds it in fstab, but with wrong file system options (udf,iso9660) which is not the one your flash drive uses.

I recently upgrade my armel NAS from etch to squeeze. During the partitioning step of the installation I intentionally left unmounted the data partition (900GB formatted XFS) but after the installation I'm not able to mount it.
I edited the fstab file adding the last line
And tried a mount but I get the message
So i noticed throught lsmod that I don't have the module for xfs
Tried installing xfsprogs but it didn't helped. So I searched for xfs-modules but seems it doesn't exists for armel architecture. Am I right? What does it means? That XFS is not supported in armel Squeeze? Assumed I can't transfer/backup 900GB of partition, is there a way to convert it on-the-fly to a supported filesystem format?
