[xcat-user] dracut error with stateful image

[Damir Krstic]

We are in process of building a RH 7 stateful image on our cluster. After
setting a node to install with this image, sometimes we will see the
following error:

dracut-initqueue[736]: Warning: No carrier detected on interface eno1

Usually, resetting the node fixes this issue (node installs properly). We
are planning to take downtime in June and install all 700+ nodes with this
image. I would like to clear up this delay / error if at all possible
before the downtime.

Has anyone seen this issue before?

Thanks,
Damir

Just checking to see if anyone knows about dracut error messages. We are
getting close to booting 700+ with this new image and I am afraid we will
have a lot of failures because of the dracut error.

Thanks,
Damir

Is the first onboard nic the one you use?

If so, I would wager that the combination of that nic and that switch/configuration has some long link-up time in play.

I’ve not seen it myself or had to use it myself, but I am aware that there is a section of https://fedoraproject.org/wiki/Anaconda/NetworkIssues

Suggesting use of linksleep *if* this is the case.
