I was unable to recover about 500GB of data but I had a recent backup of all the really critical information that was contained on it. I have shuffled the data around and replaced several hard drives – everything is back to normal and running smoothly once again.
When I returned home I was greeted by a failed hard drive. While I believe all critical information contained on it was adequately backed up and the drive is still covered by the manufacturers warranty, the bad news is it is it will require me to take this server offline to reconfigure the hardware, attempt data recovery & restore backups.
I will attempt to minimize the downtime but I am not sure how long this is going to take as there are several terabytes of data involved. Thank you for your patience and understanding.
