Server is HP proliant DL360 G4. The array is SAS 146GB.
All said there is about 10GB of space used on the drive.
Why you ask. We are getting in 4 servers that are the same make and model as the one mentioned above. All 4 of these servers are going to be set up the same way as far as OS goes. We have a working server right now that these 4 others are going to look like. Quickest route seems to be having these new servers rebuild based off a hard drive from the original.
So, we are looking for a ball park figure on how long it will take rebuild the mirror. The servers will not be doing anything else, they won't even be on the network.
