Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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.

Do you remember what was your setup and steps to reproduce?

steps to reproduce:
1. install RHEL-6.3 on the boot lun(FC Lun) with lvm layout
2. shutdown the host 
3. resize the boot lun. expand the size from 50G to 60G
4. reinstall RHEL-6.3 to the boot lun with lvm layout

workaround:
use fdisk to remove the partitions then reboot the host to re-install the OS.
Comment 5 Dave Cantrell 2012-10-22 17:44:58 UTC 
Is this problem still happening with a current 6.4 nightly build?
Comment 6 Xiaowei Li 2012-10-26 02:59:19 UTC 
I am rethinking this issue. 

This issue is a corner case. I only hit it when i resizing the boot LUN then reinstall the OS to it.

Ths anaconda will report an error when try to create mpath device since the size of boot LUN is changed and the previous partition layout doesn't work. The users have to remove the partitions or re-format the boot lun before OS installation.

I think it's difficult for anaconda to cover all this exception so i will close this bug.
