9000 MTU is based only on storage VLANs, which use 10G interfaces.<br>
<br>
All Proxmox cluster communication uses VLAN15, MTU1500.<br>
<br>
Rebooted Linksys switch, no good. Swapped to another dumb switch
without VLANs - again no good.<br>

Maybe a problem with packet fragmentation. Do you use special MTU sizes?
