Description Zachary Amsden 2010-06-10 00:34:26 UTC

Description of problem:

I have a machine which has pre-existing (RHEL5) volumes on it.  I have valuable data on them which I need to access in my RHEL6 install.

Not only are the partitions no longer detected (they were, apparently, before BZ 591030 - a DVD from 20100523 detected them fine, 20100603 blew up in the installer), but there is no way to add back the LVMs which are there on the disk using the graphical installer.

The net result is installing RHEL6 is going to wipe my system.  This is unacceptable.  I had an install of RHEL6 on the machine before, which isn't detected anymore (it exists, I can still boot into it).  It appears as if the fix to the broken upgrade functionality was to simply not make it detect the volumes to upgrade!  Hardly a good solution.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1.  Use 20100607 RHEL6 x86_64 iso to install
2.  Abort install in panic realizing it is going to wipe my entire drive
3.
  
Actual results:

Can you grab the updates image from bug 602369 comment #2, boot with updates=<location where you put that image>, and see if anaconda then detects your partitions?

Comment 4 Zachary Amsden 2010-06-11 03:57:33 UTC

Well, it detected all of my partitions if I do a "Fresh Install", but the Update option only sees my RHEL6 partition.  I assume this is the correct behavior.

BTW, to get the updates image to work on my USB key, I had to decompress it and recreate it as an ext2 filesystem.

Comment 5 Chris Lumens 2010-06-11 12:43:01 UTC

Yes, that's correct.  anaconda will only offer to upgrade partitions of the same product.
