Live CD - luks - lvm2 -- Can't mount encrypted lvm2 logical volume via Live CD

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Good evening,

While running rawhide, I can no longer boot using rawhide packages from 11/06/2010.  I keep getting asked for the LUKS passphrase.  After I enter two characters, it says the passphrase is invalid.  My passphrase is about 30 characters in length.

In my efforts to "keep all the pieces", I'm trying to access the lvm logical volume that is encrypted to save at least some of the pieces.  :-)

I perform the following steps:
1) Boot the live CD (F14) (X64)
2) Open a terminal window
3) su -l root
4) modprobe dm-crypt
5) sudo cryptsetup luksOpen /dev/sda6 crypt1 (sda6 is the encrypted LVM)
6) modprobe dm-mod
7) [root@localhost async_tx]# vgscan
  Reading all physical volumes.  This may take a while...
  Found volume group "vg_dubby" using metadata type lvm2
8) [root@localhost async_tx]# vgchange -a y vg_dubby
  3 logical volume(s) in volume group "vg_dubby" now active
9) [root@localhost async_tx]# lvscan
  ACTIVE            '/dev/vg_dubby/lv_root' [50.00 GiB] inherit
  ACTIVE            '/dev/vg_dubby/lv_swap' [9.81 GiB] inherit
  ACTIVE            '/dev/vg_dubby/lv_home' [664.25 GiB] inherit
10) [root@localhost async_tx]# ls -ld /media/*
drwxr-xr-x. 2 root root 4096 Nov  8 22:14 /media/home
drwxr-xr-x. 2 root root 4096 Nov  8 22:14 /media/root
 11)  [root@localhost async_tx]# mount /dev/vg_dubby/lv_root /media/root
mount: unknown filesystem type 'crypto_LUKS'

I'm at wits end.  Any suggestions?

Thanks

PS: I posted yesterday on "Users", but got no response.  Since this problem was originally caused by a rawhide failure, I took the liberty of posting here as well.  If that's inappropriate, please be gentle. :-)
