I have been successfully running an iSCSI setup for a while, but since updating to PVE8 and having a less than stable experience, I became less certain that my functional setup is also a supported one. I would appreciate any insight into what might be off here.
Storage is a four port Synology box with 14 iSCSI targets, each exposing a single LUN to three of the ports with static a IP on different subnets.
- Three PVE nodes sit in a cluster, each with at least two ethernet ports: One for general traffic (of which management is one VLAN), and one for iSCSI traffic - with a static IP on one of the three subnets (one node per subnet).
- The hosts file of each node has an entry for "storage" which maps to the IP of the Synology port on the same subnet as that of the storage port of the node.
- Cluster storage has entries for each iSCSI target, one example being:
As alluded to initially, each node successfully mounts the iSCSI targets and uses the LVM on the LUN for VM disks. However the syslog on each node also outputs errors about not being able to connect to the other two subnets the targets are available on. Is this an actual problem I can fix? Or if not, can I quiet it down? Or have I completely stepped in it with this setup?

portal storage
