Where do I find the VSAN logs for pool creation to figure out why a pool creation is failing? It starts, hits a few %, and then fails. I'm assuming I can dig somewhere either thru ssh or in the support logs you can generate and download.
You can generate the support bundle (Log in to the Web management interface -> Select the gear-shaped button -> Expand the VM name view -> Support Bundle)
There should be a logs under var\starwind\starwind-virtual-san\logs.
Please check MTUs and try setting them to 1500 on the entire synchronization stack.
