Can't save the edits to my fstab so i can log back into Suse

As you might envision, your description of the problem is lacking in a few critical details, such as:
1) who are you logged in as?
2) if you are getting this 'read-only mount error' at boot, how is it that you are logging in?
3) when and where is the 'read-only mount error' appearing?
4) what, exactly, does the error say?
5) how are you trying to edit fstab? directly or via the config utilities?

Can you give us a couple of those answers, please?

Additionally, you need to be running with root privs in order to edit fstab. If you've been attempting to edit it as a regular user, you won't be able to save changes.

In any case though, please provide more details, as already suggested -- J.W.

"the mount output in knoppix"

If you have booted a Knoppix CD in order to edit /etc/fstab on SuSE then your problem is that Knoppix mounts all hard drive partitions as read only. Assuming that /dev/hda5 is your SuSE / partition then you need to:
umount /dev/hda5
mount -t reiserfs /dev/hda5
and then edit /dev/hda5/etc/fstab

more information

I am trying to edit the fstab with either Knoppix or Suse in maintence mode by overwriting the new fstab with the old one.

Yes i got 2 errors and tried to run Reiserfsck --fix-fixable

su
chroot /mnt/hda7/

he error I get is
bash:/dev/null:Permission denied
knoppix:/#

vi /etc/fstab

press i and edit, then press Esc, and then type :w so save and :q to exit, then restart the comp with Ctrl+D.

Got this error

--Insert-W10:Warning:Changing a reaonly file
E325:Attention

(1) Another person may be editing the file

(2)Edit session for this file crashes
In this case use :recovwer or vim -r /etc/fstab
to recover the changes if did this already delte swap file ?etc/.fstab.swp to avoid this message

E303 Unable to open swap file for "/etc/fstab",recovery impossible

E505:"/etc/fstab" is read-only (add ! to override)

Yeah, an fstab config problem...lovely, huh? Honestly, the best way to fix this is to load the SUSE CD and select Installation from the menu options. Let it boot the kernel and proceed along until it finishes the system analysis section. At this point, YaST will attempt to detect existing Linux installations and when it notices that you have SUSE installed it should give you the option to perform a repair session. From here, you can select some manual repair parameters or just have YaST do an auto-repair. I would just go with the latter, but if you desire to get straight on with a file check that should work as well.

YaST should then verify your fstab file and present you with errors that it finds.
Make the needed changes at this point.

On your next boot you should be fine.
