[SOLVED] O.S. Crashed as a result of messing up with / permissions

Hi,

ok, so did you try, sda3, sda4, ...

Can you confirm that you only have one hard disk? "sda" refers to the first scsi (or sata) device.

Also do you know what file system you are using? ext3 was just a guess on my part.

runngin "fdisk -l" would be pretty useful for everyone involved...

Ahh, that was the command that for some reason wouldn't come to mind back in post #14.

Thanks,

Also you shouldn't need to specify the filesystem type, so that would eliminate another variable that could be causing prob;ems

mount /dev/sda3 /mnt/somewhere

@everyone, This sounds stupid but... I don't know what file system i am using. And i tried sdaN till N=5. Got the same error. I will try the other alternatives you specified right now. Thank you all.

No, that's fine. As you're not dealing with a corrupted filesystem or such, there should be no issue with the root filessytem type being detected just find on mount.

According to fdisk -l "linux" and "linux swap" rite against /dev/sda8 and /dev/sda9 respectively. From sda0 to sda7 there are just huge positive integers. I used

Quote:

mount /dev/sda8 /mnt

Got this

Quote:

mount: /dev/sda8 already mounted or mount busy
mount: /dev/sda8 mounted under /

I used

Quote:

chmod 755 /mnt

also,

Quote:

chmod 755 /dev/sda8

still didn't work. Should i try it for sda9 too?

Yippppieeee!!!! Finally recovered. The '/' had turned read only. This was very useful to me.

Quote:

mount -o remount,rw /

And then i did

Quote:

chmod 755 /

which was successful!!

All your replies are much much appreciated. Thanks a ton...

austintx · 07-24-2012, 03:56 PM

Glad it was resolved
