Hi Todd,<div>Did you create a file journal (mkfs...) after you executed the command?:</div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">

<div>3) mkfs.ext4 /dev/mapper/abc     &lt;--- i like to use ext4.  Do research on this journal if you&#39;re not clear. </div><div>Now that we got it settled.  Come the fun part- automounting:</div><div>4) configure your /etc/fstab</div>

Hi All,<br>
<br>
I can set up &quot;/dev/mapper/lin-bak&quot; with<br>
<br>
    # cryptsetup luksOpen /dev/sdb1 lin-bak<br>
<br>
but it disappears after I reboot. This messes up my<br>
crypttab/fstab. Any idea what I am doing wrong?<br>
<br>
Many thanks,<br>
