Title
vRanger 5.2 virtual appliance replication to ESXi 4.x hosts fail. -
Description
Replications fail with
FATAL repl_wrong_size target phys:XXXXXXXXXXXXXXXXXXX has the wrong size [at slave_main:571]
FATAL internal error [at pkt_recv_unlock:82] -
Cause
The VM in question is using Change Block Tracking (CBT), and the CBT header file has likely become corrupted/unusable.
-
Resolution
1) Disable CBT on the VM in question by right-clicking on them in the vRanger "My Inventory" screen and selecting "Disable Change Tracking".
2) In the VMware vSphere client, take a NEW snapshot of the VM. Do not include virtual memory in the snapshot, and do not use guest quiescing.
3) When completed, go back into Snapshot Manager and perform a "Delete All" operation. Note: do not simply delete the snapshot without doing a "Delete All", or the change tracking files will not be removed from the VM as desired.
4) When completed, re-enable CBT on the VM and re-run the replication. The replication should now proceed normally.
