Hi,
I have a little HP Proliant microserver running ubuntu server and when I installed it I used encrypted LVM. I now want to add a new 2TB disk. I have added the disk to the box and can see it with fdisk -l.
The next thing I want to do is add it to the existing volume group so I have one big drive (I'll make backups on an external device using unison as not much will change each day).
The LVM commands seem straight forward (pvcreate, followed by vgextend I think), but what I'm not sure about is how to handle encryption. Do I run cryptsetup first then the LVM commands? Do I use the same password as for the current harddrive and do they figure out they are working together or will I need to enter the password twice?
Can someone help?
Thanks.
