I had 3x 500GB drives in my server, with a bit under 1TB of data stored. One of the 500GB data drives went bad, so I removed it from the pool, which left the other data drive at 99% and the system drive at 87% capacity. I went and purchased 2x western digital 1TB "green" drives to add as new data drives, which went fine. I then removed the other 500GB data drive from the pool to migrate that drive's data over to the new drives in the pool; the drive is older and I just didn't want to risk losing data off of it.
So now I am left with this scenario: the system drive is still at 87% capacity, and the two new drives are at 38% each. I'm not sure if I fully trust the system drive, since it's the same age, make, and model as the drive that went bad, so I want to migrate as much of the data off of that drive and onto the new drives (I also intend to add a couple more 1TB drives in the next month or two). However, I don't see a way to do this. Is there a way to tell WHS to rebalance the storage pool manually
No.
or is there a way to tell WHS to use the system drive for data storage only if the other two drives are nearing capacity?
That's how it works now. However, WHS will not move data unless absolutely necessary (which is why the data is still on that drive). Any data added to the server from now on will go the secondary drives first.
I really just want to make sure I don't lose that data
If you are that concerned about losing the data on that drive, you should enable Folder Duplication on your shares.
if I do lose the boot drive, I'm OK with having to reinstall the OS, but losing data isn't an option.
Thanks,
Pete
