Creating an encrypted lvm logical volume

I wanted to create a secure place to store ssl keys, etc. I decided to create an lvm logical volume and encrypt it. Here's what I did:

1. Create the logical volume (LV):
   lvcreate --size 5G --name lv_secure vg_name
2. Encrypt the LV:
   cryptsetup luksFormat /dev/vg_a001/lv_secure
3. Verify the LV is encrypted:
   cryptsetup isLuks /dev/vg_a001/lv_secure && echo Success
4. Open the secure volume and create a mapped device named "secure":
   cryptsetup luksOpen /dev/vg_a001/lv_secure secure
5. Get info about the mapped device:
   dmsetup info secure
6. Create an ext3 file system on the mapped device:
   mke2fs -j /dev/mapper/secure
7. Mount the mapped device:
   mkdir /mnt/secure
mount /dev/mapper/secure /mnt/secure
8. When you are done, unmount and close the secure device:
   umount /mnt/secure
cryptsetup remove secure
