Description Philippe Rigault 2002-10-14 18:19:08 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.1) Gecko/20020827

Description of problem:
Installer crashed during 'Upgrade Existing System'
System information:
  i686 laptop (Dell Inspiron 8000) with two hard disks
  hda has ext3 partitions
  hdc has one large LVM partition (created with LVM under RedHat 7.3)

The install fails when trying to detect existing partitions (detailed trace
included below)
If I remove physically the hard disk that has the LVM partition (hdc), the
install works successfully.

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


How reproducible:
Always

Steps to Reproduce:
1.Create an LVM partition on a hard disk in a RedHat 7.3 system. (I have ond
hard disk setup with one large LVM partition for the whole disk)
2.Reboot the machine with RedHat 8.0 install CD 
3.Select 'Upgrade Existing System' duering the install. The install crashes upon
detection of existing partitions.
	

Actual Results:  Install crashed, unable to upgrade system.

Expected Results:  Install should recognize LVM partitions, or at least ignore
partitions that it cannot deal with instead of crash.

Additional info:

Comment 1 Jeremy Katz 2002-10-14 18:47:51 UTC

If you go over to tty2 and run vgscan by hand, what sort of error message do you
get?

Comment 2 Philippe Rigault 2002-10-14 19:19:53 UTC

-/bin/sh-2.05b# vgscan
vgscan -- reading all physical volumes (this may take a while...)
Segmentation fault

Comment 3 Michael Fulbright 2002-10-24 19:00:50 UTC

But if you run vgscan when you reboot into 7.3 it has no problems?

Comment 4 Bill Hilf 2002-10-25 01:44:44 UTC

I'm having a similar problem.  Two HDDs in an i686 IBM ThinkPad 600X.  hd0 is
HPFS/NTFS (W2K), hd1 is Linux Native (RH 7.3).  RH8 anaconda install crashes
when trying to 'upgrade exisitng' or 'install workstation'.  Don't have a
traceback, the 'save to disk' failed to write to my floppy.  But this is always
reproducable.

Comment 5 Michael Fulbright 2002-11-01 17:55:45 UTC

Has the original bug reporter had a chance to try running vgscan on their 7.3
system?

Comment 6 Philippe Rigault 2002-11-01 19:53:46 UTC

>Has the original bug reporter had a chance to try running vgscan on their 7.3

No, because this machine is now upgraded to 8.0 (physically unplugging the hard
disk containing LVM partition allowed the install to go through) and I reduilt
partitions on that disk too,so I won't be able to test either the LVM partition
or 7.3 on the same setup. Sorry.

No problem, good to here you have it working!
