Using iser instead of tcp as a transport for iscsi?

[hdemmink]

I am using scsi-target to serve LUN's to a cluster of proxmox ve boxes. They are networked via infiniband adapters, and currently working using ipoib. I'd like to get higher performance using native infiniband, but in order to do so I need to convince proxmox ve to tell open-iscsi to use iser as a transport instead of tcp by default.

I've tried putting:

iface.transport_name = iser
node.transport_name = iser

in /etc/iscsi/iscsid.conf, but that doesn't work. I think the individual node configs are overriding it. How can I make proxmox ve use iser instead of tcp as the transport_name?

Sorry to revive a dead thread, but since no one else answered, and I had to figure this out for myself, maybe this will help someone else.

I just got this working, here's the process:

On the iSCSI target, make sure that iSER is setup.

login to each PVE node and run the following:

# iscsiadm --mode node --logoutall=all
# iscsi_discovery <target IP address> -t iser -l

Then create your iSCSI/LVM config using the Proxmox GUI as normal.

I have not tested to see if this is persistent across node reboots. If it isn't, then I presume it could be addressed via an init script.
