Software :: Filesystem Supported But MTD Not Mounted?
Feb 10, 2011
I'm having the following issue on an appliance using uClinux and MTD to access a NAND flash memory: Although the kernel has Yaffs compiled and it seems able to access the NAND, it doesn't create devices (/dev/mtdblock? and /dev/mtd?):
Code:
root:~> dmesg
Linux version 2.6.19.3-ADI-2007R1.1-svn (root@ubuntu) (gcc version 4.1.1 (ADI 07R1)) #1 Thu Feb 10 15:37:08 CET 2011
Blackfin support (C) 2004-2007 Analog Devices, Inc.
Compiled for ADSP-BF532 Rev 0.5

I am very new to linux, and I have a question regarding the filesystem check (fsck). The power recently went out and when I tried to restart linux the following error appears:
*/dev/sda1 contains file system w/errors, check forced it then goes on to say..
*An error occured during the file system check. Dropping you to a shell; the system will reboot when you leave the shell. Give root password for maintenance (or type Control-D to continue) I wasn't sure what to do, but checked some other online forums and they suggested running fsck manually - so I typed in the root password - and used the command, "fsck -A -V ; echo == $? ==" it then gave the following message
*WARNING!!! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage
*Would you like to continue (y/n)
Again, I wasn't sure what to do so i just checked no. I then manually turned off the computer and was prompted at the beginning to press Alt-3. I was brought to another screen and it informed me one of the drives was degraded and suggested rebuilding the array. I tried doing this, but it still brings me back to the original error of, "/dev/sda1 contains file system w/errors, check forced," and the process continues.
Also, when I tried to rebuild the array, I didn't backup any of the data on our home directory before doing this (which was probably a big mistake). After being prompted to type the root password, I was able to give the ls command and look at all the directories...the home directory where our data was stored was empty and I am afraid I may have lost some information. Is there a possibility that data was lost when I was trying to rebuild using the old drives?

I've had a look at some similar threads but as I'm very new to linux they're already a bit technical for me. Sorry, this calls for someone with patience. I gather from other threads that disconnecting an external drive without unmounting is a no-no, and this seems to be the likely cause. Now the disk is read only and I'm unable to change any settings through the usual control panel on ubuntu. I'm just not familiar with the terminal instructions. I tried to cut and past a few command lines from other threads but I got some warnings that proceding could damage data. Like this one: WARNING! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage.

I can't restart ubuntu, because of an error during filecheck. Something like:
Code:
usplash failed
usplash could not set to 1152x864
Mountall failed
Filesystem could not be mounted
Do a manual fsck to repair error When I run fsck, it sees some multiply-nodes, when I try to repair them, it says:
Code:
Fail: Multiply-nodes allready copied or repaired After fsck is done, I have to reboot. And the cycle repeats.

I installed OpenSUSE 11.1 on a friends computer after having a lot of trouble from ubuntu, and because I use it. It was working great when she got it home, but it locked up randomly and wouldn't unfreeze so she turned it off and when she rebooted She got an error about there not being a file system present and that she needed to run a mount command, which didn't work. After that, now it just says that there is no files system present and you ge tthe basic prompt. I had her run a live cd and run Gpartd and check and repair the partitions, but it did nothing.

I run Windows Vista and Ubuntu 9.10 dual boot. Today while booting windows, it informed me that there was something wrong with my hard disk and it would perform a check, and made some fixes.
Only when I wanted to boot into ubuntu again did I realise that the disk check had corrupted my linux partition. Ubuntu's load screen shows up, but just before the login screen it says that the filesystem could not be mounted.
Is there a way I can fix this? And how do I prevent windows from doing the same in the future?

I've ran fsck -c on the (unmounted) partition in question a while ago. The process was unattended and results were not stored anywhere (except badblock inode). Now I'd like to get badblock information to know if there are any problems with the harddrive. Unfortunately, partition is used in the production system and can't be unmounted.
I see two ways to get what I want: Run badblocks in read-only mode. This will probably take a lot of time and cause unnecessary bruden on the system. Somehow extract information about badblocks from the filesystem iteself. How can I view known badblocks registered in mounted filesystem?

I am trying to do a fsck on my ext3 partition, but so far failed to let the system come up in single user mode and having the partition mounted read only. It says in the kernel parameter that it is read only (RO) but still mounts it RW. A remount with mount -o remount,ro does not work, since / is always busy. what to do to get a fsck done? I don't want to boot into a rescue system, this should be possible on a running system (like Windows does it, when rebooting)

For example we have a PC with Linux and, let's say, ext4. It is connected to another PC with Linux and Samba-shared dir.First PC mounted shared dir of the second one. So it's in the filesystem, for example in "/mnt/000/". What will happen if I unplug the net cable from first PC? Will ext4 on the first PC crash so I'll have to perform fsck? I know that hot unpluging of mounted HDD probably will make filesystem read-only available and generally damaged.

I am trying to figure out a totally odd behavior of the ext3 filesystem mounted in Ubuntu 9.10. There is a Korn Shell script, part of which does the following in the loop:
while ((1)); do
mv dir1/file dir2;
if [[ ! -r dir2/file ]]; then
echo "ERROR"
ls -l dir1/* dir2/*
exit 1
elif
echo "OK"
fi
done
Given that dir2/file always exists and that I do not move it asynchronously with "&", my script should never hit the "ERROR" statement. The odd thing is that it does, and quite randomly (no pattern at all). However when it does hit the ERROR case, ls -l prints that file is in dir2 and it is readable! I tried using "-e" instead of "-r" test - no luck. I never seen anything like this in 10 years of my programming experience. Same script worked fine on Fedora 11, and yet it wouldn't work on Ubuntu.

At boot time, before entering Runlevel 3 the HDD will go mad when mounting tmpfs on /dev/shm...
Code:
EXT3 FS on sda1, internal journal
EXT3-fs: mounted filesystem with ordered data mode
/dev/sda1 on /boot type ext3 (rw)
tmpfs on /dev/shm type tmpfs (rw)
INIT:Entering runlevel 3
It will go on and on at the tmpfs on /dev/shm type tmpfs (rw) until i press ctrl-C...then I will stop whatever it is doing, let the hdd rest a bit, and resume normal boot..

When i type the df command i see that /dev/hda1 as a filesytem that is mounted at '/'(root). Is /dev/hda1 a filesystem. I thought that it is a partition on my hard disk that contains the root file system.

as far as i know Debian "Squeeze" has a disk check utility, but you can't run this on a mounted filesystem. Is there a way to trigger this during boot (before filesystem is mounted) ? I can run this once a month to keep filesystem healthy....

When I try to boot to OpenSUSE I get the following error during boot-up: unknown filesystem type 'reiserfs' could not mount root filesystem - exiting to /bin/sh$
This only started happening quite recently - before this I could boot to Linux quite happily.

I am trying to mount a file image, like this
mount -o loop /tmp/apps.img /media/apps
But I get the following:
mount: you must specify the filesystem type
I try ext3:
mount -o loop /tmp/apps.img /media/apps -t ext3
dmesg says:
error: can't find ext3 filesystem on dev loop6.
I've also tried ext2, vfat etc. How can I detect the filesystem type of apps.img?

I have a following problem: Recently my drive with Ubuntu 9.4 has mysteriously stopped working, i.e. when I switch the computer on it informs me that GRUB didn't find the filesystem. Well, I suppose it happens.
First, I though it was due to the drive dying, but I popped it in an external enclosure and HDTune told me the drive was fine. Wanting to recover the files on the drive before reinstalling I first tried to mount it in said external enclosure under Windows (I have Win Ext2 driver installed which used to work just fine). This time, however, drive gets assigned a letter but upon opening it Windows popped up an error saying that the drive was not formatted and whether I would like to format it then.
Unfazed by this streak of failures I tried to mount it under Linux but, alas, to no avail. I might have tried every single -t operator under mount command but it still won't budge and let me mount.

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.

My home connection is dialup via an 8-bit ISA modem. I plan to use the old box with the modem in it as a gateway and do my actual work on this laptop. Connection away from home is not so easy to get in my area.
SuSE 6.1 has no problem operating the modem, so the hardware works. SuSE 6.1 can't seem to make anything else work though. How can I configure Debian to see and operate this modem?
SuSE sees the modem on /dev/ttyS1. The same chat script does nothing on jessie. I'm guessing that jessie is just not seeing ISA.
I'm able to install packages onto the box via a usb drive but that's only on the days when the local coffee shop's wi-fi actually works, which is rare.

I am new to Debian Wheezy and I can't install anything. Ever time I try to install a .deb file I get the message saying that installation is not supported by backend. Also I'm unable to install from the terminal; it always says something like "path not found" or "file doesn't exist" (I'm on my phone so I don't have an exact error detail). Everything I've read tells me to install something to fix the problem but I can't install them due to the same error.

I just got a new DVD burner and decided to get a cheapest burner (an LG SATA burner) I did not have much preferences on either IDE or SATA so I just got a serial ATA. K3B burns DVD's just fine, but the speed is pegged at 1x even though writing speed specified was 8x. Device buffer is fluctuating from 0 to 80% all the time, which seems to suggest that the data is not being fed into the drive at good sustained rate to write faster.
I tried:
hdparm -d /dev/sr0
which I got:
/dev/sr0:
HDIO_GET_DMA failed: Inappropriate ioctl for device
doing:
hdparm /dev/sr0

My brother is a linux master and the computers I get handed down are obviously all use linux. I am trying to play a wmv file on my comp. I just downloaded mplayer but it seems not to work. I have movie player as well but it tells me the file is not supported. Read about w32codecs but they seem not to be available anymore. Maybe I need to convert the wmv to mpeg but yet I don't know how.

This thread is just for those with newly defined ATI legacy cards. As our issues seem to be a little different since we are no-longer supported in the new 11.2 by ATI. The following products have been moved to the legacy software support structure (including Mobile and All-in-Wonder Variants):
* ATI Radeon 9500 Series
* ATI Radeon 9550 Series
