Doc Type: Bug Fix
Doc Text:
Cause: The user entered a long form IPv6 address in the installation configuration file, e.g. 2001:0db8:85a3:0000:0000:8a2e:0370:7334 Consequence: The installation failed as Ironic could not find an interface matching this IP address. Fix: The fix was to convert the IPv6 address to short form, e.g. 2001:db8:85a3::8a2e:370:7334 Result: The installation was successful.

Comment 3 Adina Wolff 2021-12-07 18:00:36 UTC
Deployment failed on the specified version:

[kni@provisionhost-0-0 ~]$ oc get clusterversion
version             False       True          109m    Unable to apply 4.8.0-0.nightly-2021-12-06-234030: some cluster operators have not yet rolled out

Comment 4 Bob Fournier 2021-12-07 18:08:14 UTC
Is there any indication the short form IPv6 address is not being used and is the reason for the failure?
Is what is being logged in the ironic log in long form e.g.:
 2021-10-04T14:00:29.841756101Z Waiting for fd8a:216d:178e:c1df:0000:0000:0000:0003 to be configured on an interface

Different than what is being reported for the interface in short form?

Comment 5 Adina Wolff 2021-12-07 18:21:58 UTC
The log shows the following message:
Waiting for fd00:1101:0000:0001:0000:0000:0000:0003/64 to be configured on an interface

Comment 6 Adina Wolff 2021-12-08 09:25:09 UTC
Deployment on the same version with short-form ipv6 is successful


[kni@provisionhost-0-0 ~]$ oc get clusterversion

Comment 7 Bob Fournier 2021-12-08 17:44:10 UTC
Thanks Adina. Debugging with Adina showed that the problem is only occurring and logged for ironic-inspector. This is because ironic-conductor and inspector used different images in 4.8 so will need to make the corresponding change to https://github.com/openshift/ironic-inspector-image/blob/release-4.8/scripts/ironic-common.sh#L9

Comment 10 Adina Wolff 2021-12-19 12:10:14 UTC
Deployment was successful with version 4.8.0-0.nightly-2021-12-18-022810.
Relevant part of install-config was:

    provisioningNetworkInterface: enp0s3
    provisioningNetworkCIDR: fd00:1101:0000:0001:0000:0000:0000:0000/64
