[SRU] NVMe FC Auto-connect is not working for Ubuntu 20.04

[Laurie Barry]

[SUMMARY]

Auto-connect is not working for Ubuntu 20.04. However manual nvme discover and connect commands works.

root@ubuntu2004:~# uname -a
Linux ubuntu2004 5.4.0-25-generic #29-Ubuntu SMP Fri Apr 17 15:06:57 UTC 2020
x86_64 x86_64 x86_64 GNU/Linux

root@ubuntu2004:~# nvme version
nvme version 1.9

root@ubuntu2004:~# cat /sys/module/lpfc/version
0:12.6.0.4

The fix is to update nvme-cli to version 1.10.1 or later. Groovy currently contains version 1.12-1 so it would seem the easiest would be to update nvme-cli in Focal to the version in Groovy.

[IMPACT]

Connectivity to NVMe Namespaces are lost after an link bounce or after a server reboot.

[FIXES]

Update nvme-cli to 1.10.1

[TESTING]

[REGRESSION RISK]

No

We have a large enterprise customer planning to start their validation of NVMe FC on Ubuntu 20.04 starting in September.

Hi Laurie,

Do you have a list of patches that would satisfy this?

[Jeff Lane  (bladernr)]

Hi Laurie,
This has sat a while, I wanted to check up on it. In general, we will not upgrade userspace packages in a released version of Ubuntu, however, we can certainly backport patches to fix bugs.

Alternately, if your customer has an Ubuntu Advantage agreement with us, they can file a support case that way and our Sustaining Engineering team would take a look and do what is necessary.

I'm happy to continue working on this to push bug fixes, but to do so, I'd need to have access to the upstream git tree and a list of patches needed to resolve the issue. From there, I can work on an SRU to the version of nvme-cli in Focal.

[Laurie Barry (laurie-barry-4)]

Thank you Jeff.

Yeah, at this point I think it sits until you naturally update your
userspace to the latest packages. We don't have the BW to prioritize doing
anything
special for this one.

If we get a customer with issues with this on Focal, we can revisit this, but now that 22.04 is out with a version of nvme-cli that is not affected, this is less likely to get sponsored otherwise.
