https://beaker.engineering.redhat.com/recipes/9565391#installation


works well with RHEL-8.4.0-20210210.n.0 and dracut-049-133.git20210112.el8.x86_64

Comment 1 Lukáš Nykrýn 2021-02-17 08:22:07 UTC

Can you please add rd.debug on kernel cmdline and post here the logs? Also does this work when you drop rd.nofcoe=1 completely?

Comment 2 guazhang@redhat.com 2021-02-17 13:44:24 UTC

It works well after remove rd.nofcoe parameter from kernel line or rd.nofcoe=0

Comment 3 David Tardon 2021-02-18 09:51:29 UTC

Well, what do you expect should happen when you explicitly *disable* FCoE?

Comment 4 Lukáš Nykrýn 2021-02-19 14:21:23 UTC

we need to backport:

Comment 10 Petr Matyáš 2021-08-11 12:34:15 UTC

Verified on dracut-049-188.git20210802.el8.x86_64

option is now called rd.fcoe, with 0 disabling FCoE
