Well, now I have this problem on my only ext3 filesystem. I am at a loss 
as to what direction to go. The only common element within this problem 
is that all filesystems are local to the same host, they are all located 
on a SAN, and the controller is a QLogic 2300.

There is way to much data to backup and try any risky operations as well 
as the fact that this data is in production 24x7.

Any ideas???
