Then when I try to grow the file system it complains and won't. .

[tao] #growfs /dev/gvinum/support_mirror
We strongly recommend you to make a backup before growing the Filesystem

Did you backup your data (Yes/No) ? Yes
new file systemsize is: 2097152 frags
growfs: wtfs: write error: 8388607: Device not configured

Any help you can provide would be really appreciated . .
