Hi Bart, they have an ofed listed for ubuntu 20.04 (MLNX_OFED_LINUX-5.0-2.1.8.0-ubuntu20.04-x86_64), it states beta but seems to install just fine. If you don’t want to troubleshoot beta software I can respect that and can wait =)

I did have one other question, and this may be cosmetic, under normal conditions my initiator/target relationship looks like this, you will note iser:

May 06 02:21:16 SAN.PSC.Net scst[221485]: Loading and configuring SCST *

If I reboot an intiator, or reboot scst host, often the connections come up and don’t say iser. Dmesg still mentions RDMA:

HeaderDigest None, DataDigest None, OFMarker No, IFMarker No, OFMarkInt 2048, IFMarkInt 2048, RDMAExtensions Yes

But I often see this instead:

May 06 02:18:43 SAN.PSC.Net iscsi-scstd[4209]: Connect from 10.10.12.2:57155 to 10.10.12.1:3260

If I do service scst restart, everything comes back up iser again.

Curious if this is just a cosmetic bug or if somehow I am reverting it iscsi instead of rdma when an initiator disconnects and then reconnects. It was not always like this, just for the last month or so, unfortunately I am not sure what release started this behavior.
