move disk to zfs can crush the cluster and fail in large disks

[starnetwork]

Hi,
If I move disk for example from external ISCSI or LVM storage to zfs, it's make high load
in large disks, for example 300GB+ it's can case the local server with the zfs storage to Get completely stuck
in reason of that, all other nodes in cluster can't communicate since the server is not down but no sync
so all cluster looks broken
in reason of that the corosync process got very high cpu in all nodes
in reason of that servers start crushing in all the nodes.

move the same disks with zfs send work 100% without any issues, but it's work only from zfs to zfs and not from iscsi / lvm
any suggestion for lvm / iscsi to zfs?

Regards,

Seems you did not separated your networks (storage and cluster)?
