Description Bastien Nocera 2005-04-11 13:44:47 UTC 
After an installation of RHEL3 U4 with the attached kickstart file, 3 Logical
Volumes appear with the same major/minor numbers (58:3):
brw-rw----    1 root     0         58,   1 Mar 30 21:15 /dev/VGraid04/LVraid04
brw-rw----    1 root     0         58,   2 Mar 30 21:15 /dev/VGraid05/LVraid05
brw-rw----    1 root     0         58,   3 Mar 30 21:15 /dev/VGraid06/LVraid06
brw-rw----    1 root     0         58,   3 Mar 30 21:15 /dev/VGraid07/LVraid07
brw-rw----    1 root     0         58,   0 Mar 30 21:15 /dev/VGroot/LVroot
brw-rw----    1 root     0         58,   3 Mar 30 21:15 /dev/VGroot/LVscratch
brw-rw----    1 root     0         58,   6 Mar 30 21:15 /dev/VGroot/LVswap
brw-rw----    1 root     0         58,   4 Mar 30 21:15 /dev/VGroot/LVtmp
brw-rw----    1 root     0         58,   5 Mar 30 21:15 /dev/VGroot/LVvar

Kickstart file attached below.

Comment 2 Jeremy Katz 2005-04-12 18:03:22 UTC 
Is this the installed system /dev or the installer /dev?  And the ks.cfg you
attached has all of the partitioning info commented out.
Comment 3 Bastien Nocera 2005-04-13 08:08:17 UTC 
The ks.cfg is the one generated after a manual installation. I'm checking about
the /dev.
Comment 4 Bastien Nocera 2005-04-13 10:52:56 UTC 
/dev is the one in the installer's root, not the one on the installed system.
Both the automated installation with the kickstart, and a manual installation
will fail.
The kickstart installation will go through but the vgscan after reboot will fail:
"/dev/VGraid06/LVraid06: The superblock could not be read or does not describe a
correct ext2 filesystem"

The manual installation will throw an error:
"An error occured trying to format VGroot/LVvar. This problem is serious and the
install cannot continue."
and
"mke2fs: /dev/VGroot/LVvar is mounted, will not make a filesystem here!"
Comment 5 Jeremy Katz 2005-04-13 15:33:04 UTC 
The device nodes in the /dev of the installer are created by the lvm tools.
Comment 6 Heinz Mauelshagen 2005-04-14 11:18:11 UTC 
Does 'vgscan ; vgmknodes' leave the same major/minor duplication behind ?
Comment 7 Thomas Uebermeier 2005-05-05 12:34:09 UTC 
The customer did not try 'vgscan ; vgmknodes' as he put the system already in   
production. At the time he only tried a 'vgscan -f' which fixed the behavior. 
He looks if he can reproduce the issue on a different system, though he is not   
sure if he can get one with the same setup, therefore it is not sure, if he   
can reproduce it again.
