October 17, 20178 yr Hi, Good day! I have a 7x3TB and 1x3TB Parity setup. I think I have about 8TB of free storage. Is it possible to create a 6TB Vdisk and mount it to my Windows7 VM? I added the vdisk manually with 6000g of space and allocated it to the VM share. Thanks, Karl
October 17, 20178 yr No - not unless you want your VM to start crashing! The architecture of unRAID restricts any single file to being on a single drive. When you first create a vdisk it is created as a ‘sparse’ file on a drive which means only sectors on the vdisk that contain data are allocated real space. At this point the vdisk size can appear to be larger than the physical drive as most of its space has not yet been allocated. As you use it the physical space allocated will start to grow. When you reach the limit of the free space on the drive holding the vdisk then writes will start failing, and this typically crashes the VM.
October 17, 20178 yr Author @itimpihey thanks for taking time to reply! I was wondering if there is any work around for this. Maybe creating 2 separate vdisk at each drive and then using the extend volume feature on the disk management?
