OpenSUSE Install :: Error - Read Only Filesystem ?
May 25, 2010
I have double boot (windows7 and Opensuse) on my laptop.
My problem is when try to login Opensuse says Read only file system.(While booting a lot of things FAILS(written red) because of Read only file system). So i can't login.
Cause of this problem is want to reach my Opensuse filesystem from windows7.I installed Ext2fsd software to windows7.After installed software can see my opensuse filesystem.But it looks empty from windows7.So uninstalled the software.
After that day try to login my Opensuse.While booting alot of thing fails to load it says "FAILED".and when entered my password after entering my username cant login it says ..... Read Only File System.
How can i make the filesystem Read/write permissions to my opensuse operating system.
I can't use any command beceause can't login. (I will try to boot with Opensuse Dvd)
Formated new drive with ext3 on external drive on Suse 11.1 When upgraded to 11.2, drive was not connected... Could not get mounted after that... Set up another boot drive, could not get to mount. Found post with following:
Error as follows: mount: unknown filesystem type 'crypto_LUKS' Have also got to another point where superblock was incorrect. I can use terminal, but am not a linux guru... Have looked at other posts under luks, but can not find a solution.
Upgraded from 11.1 to 11.2 using GUI (YaST and Wagon)
Machine stops on boot and says:
fsck failed. Please repair manually and reboot. The root file system is currently mounted read-only. To remount it read-write do: bash# mount -n -o remount, rw /
Attention: Only CONTROL-D will reboot the system in this maintenance mode. shutdown or reboot will not work.
openSuse v9.3 (Yes, it's old)linux 2.6.11.4-21.17-smp i686At some time after July 28 the entire filesystem has become read-only. It was functional on July 28, the last time I logged into the machine and edited a file. Even as the superuser when I attempt to change, say, the permissions of a file, I get:
Code: > # chmod 777 /opt chmod: changing permissions of `/opt': Read-only file system
During the file system check of an ext3 partition at boot I get the following output:
The super-block could not be read or does not describe a correct ext2 filesystem. If the device is still 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 super-block:
I'm then forced to login in as root and given the following prompt:
I'm reluctant to do as advised by the output and run e2fsck -b because it is not an ext2 filesystem.
Although I can still enter runlevel 5, it doesn't seem to recognise mouse and keyboard input in KDE so my system is effectively redundant at the mo. For this reason any short term workarounds are welcome, but a fix is needed. This problem is part of a longer saga to do with recovering a Windows Vista installation which started failing to boot. I have used both Vista and SUSE tools to try and recover my bootloader to no avail, and this has been the result. If more detail about this is needed please ask and I can explain what I have done.
Yesterday I post this note, because I've an urgent issue with the filesystem in opensuse 11.4, used like VMWare guest OS, over VMware Server 2 for w2k3 64bit like a host) opensuse 11.4 Filesystem goes read-only in VMware
But, Novell have a fix published for SLES 10, with the 2.6.16.46-0.12 kernel version .
I'm using a Opensuse 11.4 with the 2.6.37.6-0.5-desktop kernel version. May be related with the LSI virtual scsi hardware?
Because exists a fix for SLES 9, 10, RedHat EL 4,5 and Ubuntu 7.10, but doesn't work in opensuse 11.4
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 have multi-version Kernels on a Dual Boot WinXP / openSUSE 11,3 box. It's been a LONG time since I needed to boot to Win XP and now that I find that I can't get to it, I can not say for sure what I did to break it. Looking back, I suspect that the method I used for the recent removal of one of the Kernel versions may have been innappropiate. Rather than unchecking in versions/package groups I may have just removed the unwanted kernel in the package list. Not sure. I've tried dinking around with menu.lst and Yast Boot Loader to no success. I get errors depending on what I messed with. Didn't try to reinstall grub until I checked here for help with a fix.
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 am experiencing a problem with virtual box 4. Did an install from binary, and everything went ok and virtual box launches, but once I have created the virtual disk and the want to run it, I get an error, and the log says that it has to do with the ext4 filesystem and has a known kernel bug. How does one go about sorting this out. Here with the log from virtual box.

Today, I start my computer, got some filesystem error, prompt message ask me to run fsck manually, and I did so, then I can login my system, but the panel of the desktop can't showup. How can I get back my panel?
I have 64bit install with CentOS release 5.3 (Final)It's been stable for about six months. What happened a while ago is really weird, I haven't messed with anything lately but the entire /home filesystem became read-only. Can't write, can't delete to anything on /home. The other filesystems are fine. I am root, and the permissions look normal. My directories and files are writable and readable.
root@atlanta [/home]# touch foo.txt touch: cannot touch `foo.txt': Read-only file system root@atlanta [/home]# ls -l
This is very bad even in 11.04! I have an usb disk 40 Gb. And I was loading it with data real fast (svn). At once I could no more write, Read-only file system was reported. I reckon that problem from years ago on redhat, so I try to fix it. But It became worse. It was severe damaged. I created a new filesystem while the disk was out the usb-box and directly connected to de IDE. Started all over, and the error also. Tried to repair with no luck. It looks like the journal get overrun but I'm not sure. However I do think its reproducible. I did it 3 times now and now I am very sick of it. This is happening on a updated 10:10 to 11:04 system, a few weeks ago.
I have been given a headless linux system running from a SD card. I get into it by putty, directly to root, not other user and even /home dir. Whatever I copy or write will dissapear because is ro.
I'm attempting to build a load balancing cluster for shared web hosting clients and the only thing left is security. Given the track record with some of these sites, I don't trust them being centralized. We've had rootkits on some of the other servers that replaced system binaries, mostly ssh to capture passwords. I figured the only real way to lock it down tight enough to keep this from happening is to use a live cd for the filesystem or read-only toggle USB stick. But I also need to mount a rw drive to store the clients data and config files that are bound to change.
Is this really the way to go about this? If so do I simply make a live cd iso and edit the files within to handle mounting a rw hard drive and linking data and configuration files to that drive? I've considered just leaving all the data on the physical hard disk and mounting it as ro on boot for binaries and such but can't that just be changed with the right permissions?
I'm gonna buy a 1.5 TB HDD to put there backups, videos, and stuff like that, and i was wondering what Filesystem should i put there considering that it will be used for backups (mostly) and I must count with that drive in case of something going wrong.
With the release of openSUSE 11.3 I decided to upgrade my three-year old computer which is running 11.0 and has been running out of disk for the last few months. I bought a new 500Gb HDD and installed it as the master drive, and moved my old drive to the slave. I installed 11.3 on the new drive. Too easy.Then I tried to mount my old drive so I could move my account files across. I wasn't able to mount the drive, which uses LVM (Logical Volume Manager). Is there any reason this wouldn't be recognised by 11.3?Then I tried to mount my new drive from my old system but 11.0 doesn't have support for the ext4 filesystem. I loaded the ext4dev kernel module with no joy:
I am fully aware that these following photo's are not all required for a full understanding of my issue, but I will post them regardless. Checklist to see if my computer meets best results possible for the installation. Screenshot.jpg These photos showing here are where I plan on Installing Ubuntu

NOTE: The installation has started, but only to shortly be stopped by my error message.

This is my ERROR!!! message

No matter what I try to click on, the window simply ignores the command, regardless of the amount of times I issue the command.
I am installing Ubuntu 9.04 Desktop on my system. using entire disk. my disk is new one. first time i installed ubuntu on it successfully, used it and installed new kernel and some upgrades. all were successful.but on installing some drivers, its files system corrupted. so I had the need to re-install the OS again. NOW , when i am installing the OS, it gives error "(Errno 30] Read only filesystem" explaining that either CD/DVD is corrupt or HDD is corrupt. temperature of the environment may be high. I changed the system , ehanged the environment, moved to some cool place, changed CD drive and CD (after making new one from ISO), changed the HDD but all useless, error is there,
while installation is in progress my sda1 is mount on /target. when i see fstab, here in the line of /dev/sda1 ,error=remount-ro is observed. sometime installation gives error no 5 sometimes it gives error no 30 but both the errors convey almost same message explaining that either HDD is corrupt or CD. As i have explained that I changed every thing including HDD and CD but the error is same.
I want to install 11.04 next to my working 10.04 system. First I need to make room for the new system so I have booted from a live cd and started GParted. In GParted the partition with the 10.04 system on it, /dev/sda1, has a red circle with an exclamation mark in it and I cannot resize it. When I doubleclick on /dev/sda1 there is the following warning
Quote:
Failed to change to directory '.'(Stale NFS file handle) Failed to change to directory '.'(Stale NFS file handle) Unable to read the contents of this file system! Because of this some operations may be unavailable.
The following list of software packages is required for ext4 file system support: e2fsprogs v1.41+.
The 10.04 system is working and has worked like a dream for a couple of years and the machine has never had any other system on it. Why would the live CD not be able to read ext4 fs?
I'm running CentOS 4.3 on a VM which is an application server for Quinstreet. trouble is when i keep coming in during the mornings it seems to keep making this root filesystem read only. There is no pattern for this and neither is it clear in the messages log why this keeps happening.
Background: My mother's HP laptop had Ubuntu and Vista on it, Ubuntu my brother's doing. He decided he wanted to take off Ubuntu yesterday (he had forgotten the password), and deleted the partition that it was contained within. The computer now boots to this error.
Inventory: We no longer have the install disk for Windows Vista, he cannot tell me what version he used of Ubuntu, what partition it was on, any of the specs for the machine, or generally any information about the system. All I am aware of is that error on the boot-up screen. I have nothing else to work with.
I would like to remove Grub, and Ubuntu, and leave Windows intact (the request of the owner of the computer), but I have no idea what commands I could use to get rid of either when I can't access Windows, or how to properly remove them if I did access Windows.
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 have an encrypted filesystem that I've decided I don't want encrypted anymore. Seems the easiest way to do this is simply reformat the filesystem, but I can't. If I try to do it in YaST2 I get either system error code -3005 (unknown) or -3008 (apparently in use). When I try to do it from the command line I get:
Code: frylock:/home/joel # umount /dev/sdb5 umount: /dev/sdb5: not mounted frylock:/home/joel # mkfs -t ext4 /dev/sdb5 mke2fs 1.41.9 (22-Aug-2009) /dev/sdb5 is apparently in use by the system; will not make a filesystem here! frylock:/home/joel #
It's unmounted, I don't know how to make it any less in use than that.I can't delete the partition because it's not the last logical partition in the extended partition.
I am creating a raid10 for our studio. I just realized after creating the filesystem that I would like modify one of the parameters - the blocksize. My original command:mkfs.ext4 -b 2048 -L insightRAIDvol /dev/md0I know want:mkfs.ext4 -b 4096 -L insightRAIDvol /dev/md0Is it ok to just issue this command even though a filesystem already is in place?I am hesitant to try this without knowing what the ramifications of this might be for the superblocks or some other unknown parameter to me that might cause problems in the future.As well I know I could rebuild everything from scratch but that's a day and a half of rebuilding
I have a nfs exported filesystem but after each reboot I have to restart the NFS server twice to make it actually export the filesystem.
First restart always fails with:
Code:
Shutting down kernel based NFS server: nfsd statd mountd idmapd done Starting kernel based NFS server: idmapdexportfs: Warning: /home/teradisk/Share does not support NFS export.
