Hi, Morgan. Regardless of which technology you use on your domain storage (FC, iSCSI, NFS, Ceph...) if it reaches Critical Space, your VM will pause. What is my practice with regard to this: I always create a Domain Storage with double or half the space left over so I don't run out of space when a snapshot is created.
Please correct me if I'm wrong haha BR.
