I posted this a few days ago: Unable to write to root partition
We thought that an add on card may have been conflicting with the motherboard, so we installed a new motherboard. After that everything worked fine, and we were able to run the server for two days without any problems. Now all of a sudden, we're getting the same error (read only filesystem).
The question is, why did the HD take two days to fail again? Is this normal? Is it a sign that something more than the HD is broken?
