VMs crashing

[dreeves]

We have 2 tickets open on this. 07819627 and 07820223. Both tiskets have escaleted but I thought I cast a wider net here. We had Veeam CDP I/O filter 12.2 installed on two vSphere 7.03 clusters running 115 jobs all of the time and things were fine.
We upgraded two of our clusters to vsphere 8.0 U3g. All the VMs in those clusters have the veeam cdp storage policy attached. We use vsphere lifecycle manager. After all of the hosts were upgraded we then start ran the vbr i/o filter wizard with drs off . Then we started using the LCM to push out the new i/o filter. During this random VMs would get to 68% in the vmotion process for entering maintenance mode and then lock up. The VM became unresponsive and the process for the VM had to be killed via ssh. We had an idea about removing the cdp storage policy. When several VMs were selected and the policy set to datastore default, some of the VMs took a long time to change that settings and then they locked up. Not at 68% but other lower percentages. We found this kb at Broadcom wihich sounds very much like what we encountered. https://knowledge.broadcom.com/external ... veeam.html There are three of us here working on getting all of this worked out and each of us have a feeling this issue is somehow related to veeam cdp. We're unable to upgrade the i/o filter using normal methods because we have a large likelihood of VMs becoming unresponsive. We're looking for help understand how/if veeam could be involved in this issue and what other methods to use to update the i/o filter on esxi hosts. Or even to remove the filter completely without moving VMs or putting the host into maintenance mode.
We have 3 other vcenters with 5 clusters and 12 hosts total. All of these were upgraded using the same software and methods and all of them are running fine. The difference is that none of those have the Veeam CDP filter.

There is also post on reddit with sounds a bit like your issue (Veeam CDP VMs hanging when backed up or vMotioned)

This CDP issue make me nervous we are running the same versions now with CDP
