Check your /var/log/messages.
Had same issue having problem with disk, then EXT journal daemon failed and remount FS as read only.

A good way to know if the disk is dying is with SmartMonTools.

Code:

smartctl -t short /dev/sda (sdX)
smartctl -l selftest

If that comes up good, try "-t long", it will take probably half a day, but a much more accurate diagnose.

If you find anything bad this way, think about replacing the disk before it's too late.

I would backup data first..

Try a live CD and see if you are able to write on the root partition.
Hope this helps.

The kernel changes file systems to read-only when it detects an error on them so yooy's posts advising to back up data is good advice.
