I set up a Storage Pool with 1 x 2TB SATA disk and 3 x 300GB SATA disks. I then created 3 virtual disks, 2 of which were "Simple" and one with "Parity" - thin provisioning, 4TB limit with a 2TB volume on that virtual disk. So far so good.
I then started copying data to the 2TB volume. After some copying 400 - 500GB to the volume, file copy would just hang forever and server became unresponsive and would not shutdown properly.
After reboot, looking at the physical disk properties, the 300GB disks were all shown as being full (100% used). OK, not expected behaviour, but lets add more space. I then added a second 2TB disk added it to the pool.
I would now like to remove one of the 300GB drives from the pool (so that I can replace it with a further 2TB drive). However, in Server Manager, the Remove Disk option is greyed out and when I try using the PowerShell Remove-PhysicalDisk cmdlet, I get a 'Disk is not empty' error.
So, my question is:
How can I move the data off a physical disk in a storage pool and then remove it from the pool?
Thanks for your help,
