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.

Doc Text:	.Installation with `autopart` utility fails with inconsistent disk sector sizes Installing RHEL using `autopart` with multiple inconsistent disk sector sizes fails. As a workaround, use a `plain` partitioning scheme, for example `autopart --type=plain`, instead of the default `LVM` scheme. Another option is to try re-configuring sector sizes, for example by running `hdparm --set-sector-size=<SIZE> <DEVICE>`. As a workaround for kickstart installations: * Restrict the disks used for the partitioning by specifying `ignoredisk --drives=..` OR `--only-use=..`. * Specify disks to be used for each created LVM Physical Volume: `partition pv.1 --ondisk=..`. As a workaround for manual installations: * Select only the disks with the same sector size during manual installation in graphical or text mode. * When disks with inconsistent sector size are selected for the installation, restrict each created LVM Volume Group to use Physical Volumes with the same sector size. This can only be done in graphical mode in the Custom partitioning spoke.	Story Points:	---

Description Direct Docs Feedback 2021-03-05 13:07:53 UTC

If the following kickstart commands:

autopart
autopart --type=lvm
autopart --type=thinp

are used when installing a system with multiple disks with inconsistent sector sizes, the installation cannot be finished. See bug https://bugzilla.redhat.com/show_bug.cgi?id=1935722

The problem should be documented and a workaround provided.
