Add LVM Storage

[GarthK]

I have a new Dell 710 with two RAID stacks. The first is mirrored 300GB spindles that PVE installs on which has the vg name of "pve". The second is a 5TB RAID5 stack split into two 2TB and one 1TB partitions. These three partitions are then grouped with LVM into a single vg of 5TB called "vmstore". An ext4 filesystem has been created on this vg and all went well. This new filesystem has not been mounted. Prob is, when I try to add a new LVM Group via the web I/F, only the pve vg shows up. Read, watched, and searched the web but no luck.

What did I miss?

Thanx,
Garth

As far as i known, if your vg (which is actually an lv) is formated, you must mount it (add it fo fstab) and add a directory-type storage in proxmox gui.

proxmox lvm group support is intended in order to store VMs raw images as lv (for example, for vm-101, you're going to have an lv called /dev/yourvg/vm-101-disk1)

if you want to use LVM volumes for your VM´s you do not need to add a filesystem as your VM´s will use the block devices directly.

I'm going to start from scratch and do it again. I did everything in that doc but it didn't show up as available in the ADD Storage pulldown until I just happened to look at it again. I added it as a directory and it worked but that's not what I want to end up with.

Thanx for the responses,
Garth
