I have a 3x 12TB RAIDZ zfs pool called zfsdata and am trying to import my Hyper-V VHDXs, however i am getting an out of space error and I cannot work out why:
I have no snapshots:
The disk image I am trying to import is 10TB with 7TB used (SelmaData.vhdx). If my calculations are correct I should have about 21.8TB of useable space on zfsdata. My other big VM (which I have successfully imported) is also a 10TB (10,000GB) image with about 2TB used.
Now... I did temporarily copy one of the disk images to /zfsdata and then deleted it (on the command line using rm) once I had imported it to the VM. I'm wondering if this file is hanging about still somewhere, although I have tried rebooting in cases unmounting the zfs filesystem helped. No change.
Can anyone shed some light on what I am doing wrong here? Thanks
