Just a followup to my fsck troubles on a virtual machine.  The original 
problem was that my virtual machine would not reboot cleanly because it came 
up asking to go into maintenance mode due to file systems errors. I had to 
get sighted assistance to bring the machine up. So then at some later time, 
I brought the system down, fixed the file systems errors, and rebooted. But 
then the next day, 'fsck -n' indicated more errors on the same file system. 
So last Wednesday I brought the machine down again. But this time, after 
umounting the file system, e2fsck said the file system was clean. So trying 
to run fsck in readonly mode on a mounted ext3 file system must not work. 
It gave error messages on a file system that was actually clean.

I guess it is good news that there were no new errors on the file system but 
now I am at something of a loss as to how to keep the original  problem from 
happening again.  I don't want to find out about file systems errors upon 
reboot because the console is inaccessible. Well, maybe this is a vmware 
question. I guess I'll have to see if I can figure out a way to make the 
console accessible.
