24.x mounted VM volumes as datasets. 25.x doesn’t. Is there a way to expand the incus volumes in GUI?
Not in the GUI.
You can change the “size” property using incus command line which will resize the underlying zvol
You will then need to do something in the VM to utilize the increased size.
Truenas specifically guides users not to use CLI, so on Truenas I don’t use CLI. I’ve successfully increased the dataset’s size before cloning, then fixed the partition within the VM. But had one instance where I ‘move’ by mistake so can’t go back and fix it. I guess I have to wait for the GUI fix to be released.
Be that as it may, the only correct way to increase the size of an incus volume after import is to use incus to change the “size” property.
This will update the database, the yaml file AND the zvol size.
No other method will do this.
FWIW, it should be safe to use incus to make this change. Alternatively, maybe you should open a feature request
