In a previous post, I talked about the Argon EON, which is a device that allows you to connect four hard drives (two 3.5" drives and two 2.5" drives) to a Raspberry Pi. I've been using this device as a network-attached storage (NAS) to back up our main NAS at home, using Open Media Vault (OMV) for management.
OMV is a package that enables you to quickly set up and manage a home server. One of the benefits of OMV is that it offers plugins that allow you to customize the features of the server installation. I found the MergerFS plugin helpful to create a virtual file system that spans the different drives. However, I wasn't able to create a RAID, as the 3.5" drives were significantly larger than the 2.5" drives.
Since I wanted to use the Raspberry Pi in the Argon EON to try out some locally hosted cloud platforms, I wanted to make sure that I could use the collection of drives in the case for this installation. Unfortunately, I didn't find similar plugins to span multiple file systems in Nextcloud or OwnCloud. So I decided to manually create a logical volume with Ubuntu's Logical Volume Management (LVM) system.
