Storage Mismatch with LVM


New Member
Dec 18, 2019
Hello, I'm new to Proxmox (and LVM) and can't figure out how to get my LVM partitioned drives to recognize for there full logical volume size in Proxmox. I have 18TB usable in a raid 6 on an H700 raid card. I have setup 1 physical volume and 2 logical (VMs - 3T, and dataStore- 15T). In Proxmox it only shows 62.92Gb for both VMs and dataStore volumes. I have worked on this for a few days so I'm really hoping it's something simple that I missed. Here are the output of some common commands you'll probably need and thanks for your help!
