I don&#8217;t connect USB drive to any of them and I don&#8217;t use the microSD cards to hold virtual machines, iso disks or backup. Rather, and I use network drives from network attached storage (NAS) to hold all my virtual machines and backups.\u00a0 I connect each of the nodes to network drives I have on a 4B 2gb Raspberry Pi running Open Media Vault.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Use Shared Storage<\/h2>\n\n\n\n<p>The primary purpose is to be able to share the network storage between all the Pimox nodes.  This way all the Pimox Nodes can access the same files off of a single location.  <br>Some benefits:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Provides one location for Virtual Machines<\/li>\n\n\n\n<li>I&#8217;m not limited to the storage on the MicroSD cards<\/li>\n\n\n\n<li>Templates and VMs can be migrated between nodes. This way you can keep a VM online when doing updates or reboots to a Node or when a Node goes offline.<\/li>\n\n\n\n<li>Provides one repository for iso images<\/li>\n\n\n\n<li>Provides one repository for backups<\/li>\n\n\n\n<li>Templates can be stored on one node, but be cloned to another<\/li>\n\n\n\n<li><\/li>\n\n\n\n<li>If you turn on High Availability (HA) and a node goes offline, the VM is automatically migrated to another node<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">My Setup<\/h2>\n\n\n\n<p>I have a 2 gig Pi 4 with Open Media Vault and a 1 TB SSD drive. The OMV shares holds all my virtual machines.\u00a0 While sharing a single drive can cause i\/o issues, I don&#8217;t run anything very read \/ write intensive so the shared ssd doesn&#8217;t have an issue with multiple VMs and nodes using it at one time.\u00a0 The key is to not boot 2+ VMs at the same time, stream from multiple services at the same time or any other set of hard drive intensive efforts at the same time. I\/O could climb and cause slowdowns or the share could be knocked offline, requiring vm reboots at best, corrupted VM data at the worst.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Open Media Vault\u00a0<\/h2>\n\n\n\n<p>I use <a href=\"https:\/\/www.wundertech.net\/turn-a-raspberry-pi-into-a-nas-openmediavault-tutorial\/\">OMV<\/a> because it&#8217;s easier than <a href=\"https:\/\/pimylifeup.com\/raspberry-pi-nfs\/\">building my own NFS server<\/a> and managing the drives, file systems, shares, permissions, etc. at the command line.\u00a0 I&#8217;m lazy that way. OVM also let&#8217;s me run BTRFS vs EXT4. Another option is ZFS, but I choose not to use it. I used BTRFS instead of EXT4 because if I move to a sata controller running off of pci, I can easily setup a raid configuration. You can also use EXT4, it works great as well and I&#8217;d be using it if I didn&#8217;t have the other option.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Backups and ISO images &#8211; A Synology NAS<\/h2>\n\n\n\n<p>My other shared storage is my Synology NAS.\u00a0 I use it to store backups, and ISO images both directly from Pimox but also from the Proxmox Backup Server I am using.\u00a0\u00a0 The VM backups on my NAS can then be uploaded to the cloud with the rest of my files.\u00a0 So I have the VM on OVM and the backups in the NAS and cloud. 3 is 2, 2 is 1 and 1 is none. I could use the NAS as a shared drive for the VMs, but then I hit up against i\/o issues from the mechanical drives and other devices using the NAS.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p>Shared network storage on a NAS is a must if you are running multiple Proxmox \/ Pimox nodes.  The configuration makes it easy to share iso, templates, backups and virtual machines.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>May 6th, 2024 In my Raspberry Pi home lab I run 3 Pimox Nodes in a cluster.
