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.

Description Jan Stodola 2020-02-18 15:41:04 UTC 
Description of problem:
Anaconda fails with a traceback when running a text mode installation on a system with disks having different sector sizes:

ValueError: The volume group rhel cannot be created. Selected disks have inconsistent sector sizes ({512, 4096}).


Installation in graphical mode on the same system shows a dialog window with an error message, which is expected.



Version-Release number of selected component (if applicable):
anaconda-29.19.2.13-1.el8
python3-blivet-3.1.0-19.el8

How reproducible:
always

Steps to Reproduce:
1. dd if=/dev/null of=disk1 bs=1 count=1 seek=10G
2. dd if=/dev/null of=disk2 bs=1 count=1 seek=10G
3. virt-install --cdrom <RHEL-8.ISO> --disk disk1,blockio.physical_block_size=512,blockio.logical_block_size=512 --disk disk2,blockio.physical_block_size=4096,blockio.logical_block_size=4096
4. start the installation in text mode ("text" on the kernel command line)
5. let anaconda use both disks with LVM partitioning

Actual results:
anaconda traceback

Expected results:
anaconda shows an error message, not a traceback.

Comment 4 Zhenyu Zhang 2020-06-15 09:58:50 UTC 
Hit the same issues on RHEL 8.3.0 Internal Snapshot 1.1 qualification compose testing

When I install RHEL-8.3.0-20200609.1 BaseOS ppc64le OS 
on the 'ibm-p8-rhevm-18.pnr.lab.eng.rdu2.redhat.com', 

it shows:
Failed to save storage configuration      
      
The volume group rhel_ibm-p8-rhevm-18 cannot be created. Selected disks have inconsistent sector sizes ({4096, 512}). 


This host has two hard disks of different sizes:
Model	Size	Logical sector size	Physical sector size
IPR-0 5ECC2700	283.79 GB / 264.30 GiB	4096 bytes	4096 bytes
IPR-0 5DBA8300	283.79 GB / 264.30 GiB	512 bytes	4096 bytes

This causes the host to fail to install the RHEL OS.

So in which version are we going to fix it?

Hello zhenyzha,

This issue is not about fail of the installation but about raising traceback instead of reasonable message to user.

Anaconda can't fix this issue, it's change demanded by LVM. You can't use disks with a different sector size anymore. See bug 1669751 for more info.
