Description molle.bestefich 2005-11-11 08:27:53 EST
Description of problem:
1. Burn-in tested the two 300 GB disks twice each.
2. Started Fedora Core 4 installation.
3. Used Disk Druid to create 3 MD RAID1 arrays:
  md0 --> 512MB /boot
  md1 --> 8GB swap
  md2 --> ~250GB LVM --> VolGroup0
4. On VolGroup0 I created one 20GB volume named Dom0Vol.
5. Finished Fedora Core 4 installation.
6. Started Konsole, entered:
  lvcreate --snapshot --name FC4_install --size 10g -pr /dev/VolGroup0/Dom0Vol
7. Done - now nothing works, most binaries yield "cannot execute binary file",
clicking anything on the desktop yields "ELF header not found" (or some such).

Additional info:
Hardware is a brand new HP DL145, with an added Silicon Image 3114 SATA
controller and two Maxtor 300 GB SATA MaxLine III harddrives.  Since installing
more than 5 GB of applications went without a glitch, and so did the initial
bootup of the system, I'm pretty sure that it's the 'lvcreate' I did that
screwed things up.

Reproduction recipe:
I'd rather not try and reproduce it :-).
I think I'll try Gentoo and EVMS instead, heh.
But let me know what you need to fix it if there's anything I can do before I
nuke it from the face of the earth..

This report targets the FC3 or FC4 products, which have now been EOL'd.

Could you please check that it still applies to a current Fedora release, and
either update the target product or close it ?

Fedora Core 4 is no longer maintained.

Setting status to "INSUFFICIENT_DATA". If you can reproduce this bug in the
current Fedora release, please reopen this bug and assign it to the
corresponding Fedora version.
