When attempting a replication it fails with:
"Error Message: 2721 - Warning: Permanently added 'cotonou.aguettant-fr.priv' (RSA) to the list of known hosts.FATAL repl_wrong_size target phys:/vmfs/volumes/DS3300-Datastore/PRAGUE/PRAGUE-flat.vmdk has the wrong size [at slave_main:571]
FATAL internal internal error [at pkt_recv_unlock:82]"
Increasing the size of the hard disk on the source VM causes this error
Increasing the size of the hard disk on the source VM, requires the same change to be done on the Replica VM
On this occasion deleting the replica and restarting the replication from scratch resolved the issue
