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 IBM Bug Proxy 2011-06-08 04:20:19 UTC 
anaconda's crash information

---Problem Description---
I think this is different than an earlier bug I opened, "RH691950- [RHEL6-GA]Anaconda crashes while working with partitions", but it is in the same area.  I'm installing using a network boot of the install media thru a VNC session, and had selected to do a custom install (intending to preserve an existing installation).  I wanted to re-format and use the existing PPC Prep Boot partition and re-use (no format) the /boot partition, and create a new /dev/sda8 root "/" partition. anaconda crashed.

Looking at the anaconda exception report, following is reported. 

anaconda 13.21.117 exception report

Found a similar bug that is fixed a long time ago. 
https://partner-bugzilla.redhat.com/show_bug.cgi?id=491945

Patch that fixed this is attached here. 

But looks like the fix should be already present. There is probably more to this. Requesting Redhat for help on this. 

Cheers,
Prem

Comment 4 David Lehman 2011-06-08 14:05:47 UTC 
It appears your swap partition (sda5) is somehow broken:

13:05:28,945 INFO    : Running... ['swapon', '/dev/sda5']
13:05:28,961 ERROR   : swapon: /dev/sda5: swap format pagesize does not match. (Use --fixpgsz to reinitialize it.)
13:05:28,961 ERROR   : swapon: /dev/sda5: swapon failed: Invalid argument

From syslog:

18:05:28,967 WARNING kernel:Swap area shorter than signature indicates


We did not modify the swap partition in any way as far as I can tell.
