I am trying to resize a secondary data disk on a Debian Linux Virtual
machine. The data really isn't all that important, its video from IP
security cameras. Since nothing has happened that needs reviewed I could
scrap it and start over. However I can't even do that.
I tried just setting the volsize to a larger value while the vm is
shutdown. zfs excepts the command, I boot up the VM but it is not
recognizing the volume properly I can see that its grown, but it errors
trying to update the GPT partition table with the new size. I gave up
shutdown VM and tried to delete the zvol so I could create a new one.
However it believes the zvol is in use and wont let me destroy it. So
something funky seems to be going on. oddly enough I set the zvol back
to the original size boot up the vm, all the data is intact and
functioning just fine. So somehow I can't break it despite doing all
kinds of things that could have and probably should have destroyed the
I am going to guess the only thing I have left to try is disable vms on
startup and reboot to see if I can then destroy the zvol and create a
new larger one. But I was hoping someone else might have another
suggestion to correctly increase the volume size.
