Description of problem: anaconda is unable to create an LV for installation on this system. This system is using a 3ware 9550SXU for hardware RAID 5. There are a total of 6 drives, each at about 290 GB, for a total of about 1.5TB. The 3ware card presents itself to linux as a 1.5TB scsi drive, mapped to /dev/sda. I've tried installing with normal partitions, and it worked fine, but for some reason, I am unable to create LVGs upon which to install the system. I've tried with varying sizes and configurations of the LVs, including some partitions outside, or all partitions as part of the LVG. In this situation, I'm afraid I need to use LVM for its capability to grow partitions. Version-Release number of selected component (if applicable): RHEL 5. How reproducible: Always. Steps to Reproduce: 1. Begin installation on system with HW RAID 5 via 3ware 9550SXU. 2. In the disk management screen, select a custom partition configuration. 3. Create an LVM partition, and place logical volumes within it. 4. Press "Next" Actual results: Bug alert window. Expected results: anaconda proceeds to partition and format the RAID. Additional info: Attached is the anacdump.txt from the last time I attempted this. You will see the following drives: /dev/hdb : Optical drive with installation media. /dev/sda : RAID /dev/sdb : USB drive used to copy the dump file. I apologize for the size of the log (1700 lines or so) but I'm not precisely sure what's relevant here and what's not.

I found a workaround. I allowed the installer to create the partitions it wanted (which were a 101MB /boot and everything else in an LVG) and then edited all the partitions it had created to suit my size requirements, and added anything that was missing. No idea why this worked.
This problem has been fixed in Fedora and will be included in the next major release of RHEL. Bugzilla is not an official support channel for RHEL. If you need this fix included in RHEL, please contact your support representative who will escalate it through the proper support channels.
