Re: cannt boot, FileSystem read only

Perhaps you are referring to the boot sequence wherein the statement is made that r/o  (read only) exists.  This is a normal function during boot...the final step makes it r/w.

I don't know what you mean by you can't boot by live CD, but it sounds to l'il noobie me like there's something wrong with your /etc/fstab file. Can you post it? And when you say you have KDE over arch linux, you mean you installed it via pacman, yes?

Re: cannt boot, FileSystem read only

I once had a problem in ubuntu that my filesystem was ro for no apparent reason...
You can try

mount -o remount,rw /

but that is no permanent solution.

Cdh: I try it but still the same.

majiq: i cant login BIOS to change the boot sequence, yes i install KDE via pacman

Re: cannt boot, FileSystem read only

With no error message? And nothing in dmesg?

Re: cannt boot, FileSystem read only

Perhaps you can try the wiki procedure ...Kernel Panics..method 2...

It will re-install the kernel and run mkinitcpio and may solve your difficulty.

Re: cannt boot, FileSystem read only

I just completed an base ftp install of arch and experiencing the same problem.

My FS (ext4) is read only and when looking at my fstab I see no UUID entries for any of my HD partitions.

ls -lF /dev/disk/by-uuid/ & /sbin/blkid tell me what my uuids are but how do i edit the fstab on a fs that is ro?

How would I go about fixing this?

From any live CD including Arch CDs .

One thing I don't understand . Is root actually mounted ro without any entry in fstab ?!

Re: cannt boot, FileSystem read only

Hello.
I had the same problem last week where i reinstalled arch 3 times becuse of root read only(only one computer).

************FILESYSTEM CHECK FAILED****************
* Please repair manually and reboot. Note that the root        *
* file system is currently mounted read-only. To remount      *
* it read-write: mount -n -o remount,rw /                            *
* When you exit the maintenance shell the will                     *
* reboot automatically.                                   

When enter control -D it says something quick on screen about /dev/shm not mounted
and some text say bla bla use iofs8 bla bla use fuser i dont now what that mean.

I could not find any direct solution when google root read only,some think is a kernel bug ,some say hdd failure (i change hdd after 3 new installations with root read only)

Now my new install had worked for 2 days and im scared to death to shutdown computer

I find this thread, but this is on a working system, http://bbs.archlinux.org/viewtopic.php?id=55221
