storage that does not have availability requirement could be migrated simply by

dd if=/dev/sourceblockdevice | ssh target | dd of=/dev/targetblockdevice

there is a design-issue blocking the way: gvinum capability should be a single capability per server rahter than per disk

it would be nice if optionally lz4 could be used as compression algorithm, if it is installed on both servers, have enough unreserved CPU capacity
