Boot Problem - Error: read only filesystem

**jaakko777** · 08-30-2005

Something unfortunate happened to me as a guest unavare of what he was doing shutted down my server from the powerbutton (he tought he was starting it up).

Well, now when i start the server all processes end up with [ FAILED ], and as error message i get a complaining that the filesystem is read only. So it cant delete or create any runfiles...

I manage to login if i choose the failsafe option from the bootloader, and thus am able to do some limited things.

I ran the e2fsck with -pf on all partitions but that didnt help.

Does anyone have a clue what i could do except reinstalling the system.

More details to help you diagnose my problem.

Running fdisk results:

Code:

&#91;root@&#40;none&#41; /&#93;# fdisk -l
cannot open /proc/partitions

So e2fsck found no problem? And you ran it on the / filesystem?

What happens if you try to mount /?

If you want to skip the long bootup process, a quick way into a failsafe is to add:

Code:

init=/bin/bash

To your boot options, which will yield a root console. From there:

Code:

mount -no remount,rw /

I ran,

Code:

e2fsck -pf /dev/hda1
e2fsck -pf /dev/hda6

(thats all of my partitions)

It says:

Code:

mount&#58; /dev/hda1 already mounted or / busy
mount&#58; according to mtab, /dev/ide/host0/bus0/target0/lun0/part1 is alredy mounted on /

Thanks for the advice, i will try this even though i didnt really understand what it will do (i guess ill find out)...

You'll need to:

Code:

umount /dev/...

before running fsck.

edit:
heh just thought about that and realized that you're not on a livecd so that wouldn't work
heh

You need to get to single-user mode before running the filesystem check on /.

Try

Code:

init 1

as root (after booting).

**jaakko777** · 08-30-2005

Ok so i do after boot

Code:

init 1
umount /

should i then do

Code:

e2fsck -pf /dev/hda1
&#40;or&#41;
e2fsck -pf /

**anomie** · 08-30-2005

Well, assuming /dev/hda1 is where you mount /, then run it on the device itself - /dev/hda1. (At times when the file system check program can get to /etc/fstab you can use either one.)

**jaakko777** · 08-30-2005

Ok i did that now and i get a clean report from all partitions now as well.

But the error persists, upon boot (and shutdown, which i did forget to mention earlier) anything the loader does is responded by either;

a) IOError [Errno 30] Read only filesystem
b) [Errno 30] Read only filesystem
c) Read only filesystem

accompanied with the name of some file or pid that it tried to operate on.
