Hello, @Danp
My pool is in upgrade, not all nodes are updated.
I evacuate the master hosts's vms to the slave node except 3-4 vms which are "very not important and can be shut for few minutes
I upgrade the master node with success
I WANT to move all vms to the master, but it deosn't have enought disk space, so i tried the following:
a. Migrate the very not important VM to the slave node ( not updated ) to have enought space to move the "important" vms.
b. Move vms of the updated master to ANOTHER pool.
I tried both:
VM running
VM halted
Thanks !
