I copied from an old server setup to fstab (unsure now why I did so), and with it I overwrote the correct uuid. When I rebooted the server it started in emergency mode and I suspect the reason is that I have wrong specs in fstab.

How can I modify the correct uuid into fstab while its unwritable? With blkid I get the correct uuid and it's found in fstab but commented out.

tried running

mount -o remount,rw /
mount: /: can't find UUID=old server uuid

Boot server startup menu, press e for edit, Line starting with Linux= switch ro to rw and add word single at the very end of the line, press f10 for reboot. Go to fstab and correct issues.

This fixed fstab and other system files being unwritable. Hope this helps someone else too

On your command: mount -o remount,rw / you are not specifying the device. For that reason, the system is looking for /etc/fstab (to see what device is your default for /).

You say you have the new UUID from blkid, then you can use the command: mount -U <NEWUUID> /

Otherwise it will keep trying to mount the UUID in fstab. Once you can write fstab, you can set the new UUID.
