I thought I would add more information:
This machine is using Stripe RAID is divided into 2 Drives (not partitions but
2 drives). The First RAID Drive has Ubuntu Server 11.04 with encrypted LVM on
dm RAID0. The Second RAID0 drive has Windows XP. the Third Single Drive not in
RAID has Ubuntu Desktop 11.10. I have not upgraded it to 12.04LTS yet.
Note: Grub does not know about the other OSes since it was installed before the
other OSes and I use the BIOs Boot Menu to select the drive to boot from.
The system no longer drops to (initramfs) and no longer asks for the
passphrase, due to constant rebooting, but it does do (grub).
When Booting to this first Drive in RAID0, I get the Grub Menu:
------------------------------------------------------------------------
"GNU GRUB version 1.99~rcl-13ubuntu3".
Ubuntu, with Linux 2.6.38-10server
Ubuntu, with Linux 2.6.38-10-server (recovery mode)
Previous Linux Versions
Memory test (memtest86+)
Memory test (memtest86+, serial console 115200)
------------------------------------------------------------------------
If I select Previous Linux Version I get the GNU Grub Menu:
------------------------------------------------------------------------
"GNU GRUB version 1.99~rcl-13ubuntu3".
Ubuntu, with Linux 2.6.38-8server
Ubuntu, with Linux 2.6.38-8-server (recovery mode)
------------------------------------------------------------------------
Selecting:
Ubuntu, with Linux 2.6.38-10server
Ubuntu, with Linux 2.6.38-10-server (recovery mode)
or
Ubuntu, with Linux 2.6.38-8server
Ubuntu, with Linux 2.6.38-8-server (recovery mode)
No longer gets me where I need to enter a Passphrase… It just reboots the
machine.
------------------------------------------------------------------------
If I chose the 'c' Option it opens the GNU GRUB Command line option"
"GNU GRUB version 1.99~rcl-13ubuntu3".
Minimal BASH-like line editing is supported. For the first word, TAB list
possible command completions. Anywhere else TAB list possible device or file
completions. ESC at any time exits.
grub>
------------------------------------------------------------------------
grub> ls
(hd0) (hd0,msdos5) (hd0,msdos1) (hd1) (hd1,msdos3) (hd1,msdos2) (hd1,msdos1)
(hd2) (hd2,msdos1) (fd0)
grub>
------------------------------------------------------------------------
If I select 'e' Option on line "Ubuntu, with Linux 2.6.38-10server":
"GNU GRUB version 1.99~rcl-13ubuntu3".
setparams 'Ubuntu, with Linus 2.6.38-10server'
recordfail
set gfxpayload=$linux_gfx_mode
insmod part_msdos

search --no-floppy --fs-uuid --set=root ######xx-x###-#x#x-x###-####x#x\xx###
Linux /vmlinux-2.6.38-10-server root=/dev/mapper/MachineName-root ro \quiet
initrd /initrd.img-2.6.38-10-server
------------------------------------------------------------------------
When I Log into my other Ubuntu Single Drive, I can browse the 256mb
filesystem ######xx-x###-#x#x-x###-####x#x but I am unable to mount the
750GB LVM2 Physical Volume Not a mountable file system. Once I get this
message after typing in the password, I can not attempt to remount it. I
had selected the forget immediately option when typing in the password.
Logging off and back on did not allow me to attempt again to mount this
Volume. Only after rebooting am I able to enter a password to unlock the
volume for the device 750GB Hard disk contains encrypted data. When I
type an incorrect Passphrase I get an "Unable to mount 750GB Encrypted"
Error unlocking device: cryptsetup exited with exit code 255: No key
available with this passphrase. click ok and can retry mounting the
device… I have selected for this test Remember password until you
logout, and typed the correct password and the drive disappears from the
browser and I do not get any messages about whether it failed or
succeeded. When I log out and back on it still does not show the drive
in the browser. After i reboot the 750GB Encrypted drive shows up in the
browser.
I have resisted reinstalling the OS on the encrypted drive. However if I
can not save my data I will call it a lost and reinstall it using
12.04LTS
I no longer get the Enter passphrase option and I have changed the
Graphics card from NVIDIA to ATI which I had to uninstall before I could
boot into my other Ubuntu drive. I think it is sad that Ubuntu can not
load standard VGA drivers when a Video card changes. I had no choice
about the graphics card since the NVIDIA card failed last month.
Please detail the commands or tools you would like me to try.
Regards,
John
