any way to force live Migration of disk on zfs over iscsi with it part down

Right now on one of my ZFS nodes the OS disk has failed and can't ssh in but scsi is still up any way to do an live Migration of the disk data with out downtime?

NO vm's running on the ZFS node. I can mount the iscsi luns on an differnt host.

If the VMs really aren't running on that node and the storage is shared, then you can simply turn it off and move the config files in /etc/pve/ by hand into the new node folder. But the storage config need to be the same.

no pve on the storage only node. Moving to CEPH and can mount iscsi and copy data over. Just want to know if there is an way to force QEMU to do an LIVE Disk move so I don't need to stop the VM and copy data in the back end.

With qemu-img you can convert the image to Ceph. If the ZFS storage lives on a different disk and the node is part of a cluster, then a simple re-install and joining to the cluster would give the configs back to the node. And the VM image wouldn't be touched.

I was able to shutdown the VM and just copy over the DISK image with an iscsi mount to an RBD mount.
