Basically no, not in a clean way for a production VM. Can you attach
multiple disks to the guest and then use software RAID0 or LVM to get a
22 TB device inside the guest?
If not, here are some options:
1. Switch to a different file system (XFS is your best bet)
2. Use LVM (and get a slight performance boost for free!)
3. Tweak file system settings (e.g. bigger block size may allow larger
files)
