Windows Server 2016 Storage Pool question

Question

Hi we currently have a server that is at capacity for disks, it has 8 1TB drives added to a simple storage pool (the resulting volume is 8TB).

We need more space on there and so I'm thinking of doing the following

Using the remove disk option on one or more of the current 1TB drives and then installing new 2TB drives and adding those back into the pool.

Two questions

1. Will removing a disk migrate the data to the remaining disks (we need to ensure no data loss) assuming enough free space on the rest of the drives?
2. Can storage pools utilize disks of different sizes or do they all have to be the same (ideally we will replace all the 1TB drives but obviously can't do that at once)?

Answer 1

Hi,

It's recommended to use the same disk size for the storage space. Replace the 1 TB disk with 2TB may not increase the storage space size.

Do you have any free slots on the machine, if yes, it's recommended to add new 1TB drive.

Answer 2

So there is no capacity to upgrade the drive size? As stated in my original question the server is at capacity for disks.

Answer 3

Hi,

It's pity to say, if there's no slot to add a new same size physical disk into the storage pool, we'd need to backup the data and rebuild the storage pool with large size physical disks.
