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.

Allow /dev/xvdN devices to be probed for metadata.

Description of problem:

Udev fails to run blkid on some Xen block devices.


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

RHEL 6.0 and 6.1


How reproducible:

100%


Steps to Reproduce:

Try and install RHEL6.x from a DVD in the host's physical drive. It boots and starts, but later says it cannot find the repos. This turns out to be because the disk metadata have not been probed during device init -- the environment is missing ID_FS_LABEL, ID_FS_LABEL_ENC and ID_FS_TYPE


We'd like to propose the attached patch be added to udev rules in both the install disk image and also the regular image. This causes the blkid probe to be run on the devices, providing the metadata which the installer then reads.
