Introduction

The first thing I do when deploying a new server is install aide, and initialize the database. The second thing that needs to be done is to move this database to a read-only partition or media.

Adding a new disk

If you want, you can add a new disk to use for the new logical volume this step can be skipped if you want the aide-lv to reside on the existing volume group. To do this, execute the following:

`pvcreate /dev/sdxn`, i.e `pvcreate /dev/sdb1`

This creates a new physical volume for the disk.

`vgcreate vg-aide /dev/sdb1`

This creates a volume group for aide called vg-aide.

Create the LV

Now, let's create a new logical volume for aide.

`lvcreate -L 4G -n lv-aide vg-aide`

This creates a new logical volume called lv-aide on the volume group vg-aide. If you skipped creating a new volume group, check the existing volume group name using:

`vgs`

This will show all volume groups. You can show information about them using:

`vgdisplay`

Creating a Filesystem

Next, create a filesystem on the new logical volume:

`mkfs.xfs /dev/vg-aide/lv-aide`

Create a Mountpoint

Now let's create a mountpoint for the logical volume:

`mkdir /aide-db`

Mounting the LV

Finally, mount the logical volume:

`mount -o ro /dev/vg-aide/lv-aide /aide-db`
