Comment 3 Radek Vykydal 2018-02-05 11:35:14 UTC
Seems to be a consequence of

For RHEV image install there is probably already /etc/fcoe dir existing on the image. I think we should be able handle this case, I'll look at it.

Comment 4 Radek Vykydal 2018-02-05 11:41:07 UTC
Could you please provide a link to HVH-4.1-20170817.0-RHVH-x86_64-dvd1.iso or similar so I can debug the issue? Thank you.

PR with fix:


You can check if the fix works for you using this updates image with the patch:

It can be applied to an installation by adding installer boot option "updates", eg:


or by using kickstart "updates" command:

Comment 7 Samantha N. Bueno 2018-02-06 10:38:46 UTC
Switching this over to python-blivet, since that is the component which the fix is for.

Also setting blocker? since this is a significant issue for our layered products (RHVH). The fix should be quite safe.

Comment 9 Jan Stodola 2018-02-06 14:37:45 UTC
FYI, updates.img from comment 6 fixes the problem for me.

Comment 14 Jan Stodola 2018-02-23 08:33:47 UTC
Thank you for confirming this is fixed for you.

Moving to VERIFIED based on comment 13.
