I have set up a Datacenter Cluster with two nodes and one Backup Server with a reverse proxy and several webservers, each on its own VM. Each node is running on a re-purposed embedded firewall device with only space for a single 512G drive (a M.2 SSD). The Proxmox Backup Server is running on a server with one SSD and three 4TB drives set up as ZFS RAID Z1 for ~7TB available.
With the default partitions on both nodes, and not being able to add additional physical SSD's, I have not found a way to use the benefits of shared storage. Also, with the VMs all located on LVM-Thin, could not shrink an oversized VM, even after using gpart to shrink the partition inside the VM; qemu-image resize did not work for me with LVM-Thin.
I am wondering if there is a better way to set up the storage partitions, volumes etc... perhaps using only 100GB for the LVM partition and then using the unallocated space on the drive for a different partition, storage pool or...? I am only using about 20GB for VMs right now. Could it be better to have a different partition plan or to rebuild nodes with a different storage system? Appreciate any ideas or suggestions. Most of the examples I read on the forums talk about adding more drives, but I am pretty much limited to one physical drive per node....
Current node setup (x2):
