 Hi All,

 Xfce 4.8
 Scientific Linux 6.2, 64 bit

 I have just encrypted my backup drive.  Is there anyway
 to get it into my fstab?

 Problem is rebooting removed the label I created in
 /dev/mapper with

   # cryptsetup luksOpen /dev/sdb1 lin-bak

 and in fstab, I can add:
/dev/mapper/lin-bak  /lin-bak  ext4  defaults  1 0

 But /dev/mapper/lin-bak vanishes on me after a reboot.

 I can double click on the icon on my desktop and
 it will mount in /media/lin-bak.  But this plays
 havoc on my scripts.  Gives me a long funny name
 in /dev/mapper too, which disappears when you
 dismount.

 Be nice to be able to get the drive into my fstab.
 If not, how do I mount it from the command line?

 If I try to mount directly, I get

   # mount  /dev/sdb1  /lin-bak
   mount: unknown filesystem type 'crypto_LUKS'

Ah ha!  Thank you!

In /etc/crypttab, how do you handle passwords with spaces in
them?  I think it gags on quote marks.

Hi Tam,

With both quotes and backslashes, I get key file missing.  So
I switched to a keyfile.

Now I get: special device /dev/mapper/lin-bak does not exist.

I can create /dev/mapper/lin-bak with
   cryptsetup luksOpen /dev/sdb1 lin-bak

but /dev/mapper/lin-bak disappears after I reboot.

Any ideas what I am doing wrong?

You need to map it in the file /etc/crypttab.

You want to configure your /etc/crypttab file to look like this:
lin-bak /dev/sdb1
