I am running Server 2012 RTM with a single storage pool containing 4 drives - 2.73TB, 1.36TB, 465GB and 148GB. There is a single virtual disk created, with thin provisioning, using the Simple layout, with a current maximum size of 2.73TB, and with 1.32TB
allocated. I want to remove the 148GB drive and replace it with a 465GB drive. When I right-click the 148GB disk and select Remove, I get a warning that Windows will attempt to rebuild any virtual disks that store data on the disk I'm trying to remove, and
that in order to succeed, the storage pool must have enough free space to accommodate the data from the disk I'm trying to remove. There is more than enough space in the virtual disk to accommodate whatever files may be stored on the 148GB disk - over 1TB
unallocated. However, when I confirm that I want to remove the disk from the pool, I get the following message:
This physical disk is used by one or more virtual disks that use the Simple (no resiliency) layout. To remove this physical disk, delete the following virtual disks: Simple
Surely the fact that it's a simple volume (rather than mirrored/parity) shouldn't affect the ability to move the data off the disk? It appears that disk removal is implemented as a simulated drive failure, forcing a rebuild of the resiliency data, rather
than by simply moving the data off the disk onto other available disks.
Additionally, after I've attempted to remove the disk, it's now been marked as 'Retired'.
Is there any simple way to remove this disk?
