Receive this error on the Virtual Appliance, a few minutes into the replication task beginning.
This happens when the Virtual Appliance tries to create a directory on the target host datastore that it resides on.
Virtual Appliance scratch disk is not large enough to accommodate the Source VM in question and we receive this error when trying create a directory on the scratch disk. The scratch disk is full and needs to be increased.
Increase the size of the scratch disk to accommodate the tasks it is presented with. The scratch disk calculation algorithm is listed below.
Size of the virtual machine = 100 GB
Change rate between replication passes = 10%
Number of simultaneous replication jobs = N
Size of virtual machine being replicated (multiplied by) virtual machine change rate between replication passes (multiplied by) the number of simultaneous replications = size of scratch disk.
Scratch disk algorithm = 100 * 10% * 3 = X
X = 30 GB
