Two weeks ago I upgraded Zerto to Version 9.0 Update 4 Build 090409252. Last week we started patching our Hosts to VMware ESXi, 6.7.0, 19898906. After patching and a reboot the VRA reconnects, but all of the VM’s that move to the Host go to Bitmap Sync and stick at 0% with no movement. We have been doing this for years, and have never seen this issue. Is this something new? I have simply been waiting until the end of the day, and then rebooting the Management servers, at which point the VPG’s start a Delta Sync and catch back up, but it’s kind of a pain. Are we doing something wrong now?
After opening a ticket with support, the quick fix was to stop and restart the Zerto service on the Management servers. Then replication started back up again.
