RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

I don't see any workaround to have this kind of DDF container be usable, hence the severity.


Version-Release number of selected component (if applicable):

Anaconda 8.5 (33.16.4.15)

How reproducible:

Always

Steps to Reproduce:

1. Setup a VM with 2 disks and boot into installer

2. Drop to shell and create a DDF container

  -------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
  # mdadm --create /dev/md/ddf --name=ddf --level container --raid-disks=2 --metadata=ddf /dev/vda /dev/vdb
  # mdadm --create /dev/md/vol0 --name=vol0 --level raid1 --raid-disks=2 /dev/md/ddf
  -------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

3. Rescan the disks

Actual results:

Crash

Expected results:

No crash and container usable

I didn't realize we already had RHEL 9 clone of https://bugzilla.redhat.com/show_bug.cgi?id=2063791 and cloned the bug again, https://bugzilla.redhat.com/show_bug.cgi?id=2109030 is now in verified, so I am closing this one as duplicate.
