CentOS - Jun 2006 - Root filesystem is suddenly mounted read-only

This is very strange.  Everything was running fine Friday night.   
This morning I walk into work and find that my root file system  
(which is actually the only filesystem besides /boot) is not  
writable.  Yet mount thinks it's mounted read/write:

   # mount
   /dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw)
   [snip]
   # touch foo
   touch: cannot touch `foo': Read-only file system

Anyone else seen this?  This is on a relatively recently fresh CentOS  
4.3 install.

Never mind, shortly after posting this the system started to behave  
strangely.  I tried to look in /var/log/messages, and the system  
locked up. It's the "EXT3-fs error (devive dm-0) in  
start_transaction: Journal has aborted" problem from a previous post  
again.  I've removed the dmraid package, but I've not yet replaced  
the SATA cable.  I'll have to do that next...

I faced the same error message yesterday.
While reboot, fsck will prompt to fix the lost chain error.
Back to normal after all the lost chain fixed.
