New volume not showing in Proxmox Dashboard

[Uuugh]

Hi,
I am lost. I have a new installation of Proxmox 6. My goal is to add a new thin storage area for vm's on separate physical storage from pve. But I can not see the storage/volumes in the Proxmox front end. I have followed every manual and post I could find ...so I am obviously missing something. More than likely I can't figure out how to use the pvesm command. I have looked for it to show in each of the steps I followed from fstab to lvcreate. Here is my process. Please explain (or point me to a good reference) for what I missed. Thanks a bunch!

sgdisk -N 1 /dev/sdb pvs PV VG Fmt Attr PSize PFree /dev/sdb1 vg-taichi lvm2 a-- 238.47g 0 /dev/sdc3 pve lvm2 a-- <57.26g 7.12g reboot pvcreate /dev/sdb1 vgcreate vg-taichi /dev/sdb1 lvcreate -l 100%FREE --thinpool tp-taichi vg-taichi lvcreate -V 250G --thin -n tv-taichi_data vg-taichi/tp-taichi lvs LV VG Attr LSize Pool Origin Data% Meta% Move Log data pve twi-aotz-- 26.76g 3.38 1.63 root pve -wi-ao---- 14.25g swap pve -wi-ao---- 7.12g vm-100-disk-0 pve Vwi-a-tz-- 8.00g data 11.30 tp-taichi vg-taichi twi-aotz-- <238.24g 2.07 11.47 tv-taichi_data vg-taichi Vwi-a-tz-- 250.00g tp-taichi 1.97 mkdir -p /mnt/taichi_data mkfs.ext4 /dev/vg-taichi/tv-taichi_data mount /dev/vg-taichi/tv-taichi_data /mnt/taichi_data nano /etc/fstab /dev/mapper/vg--taichi-tv--taichi_data /mnt/taichi_data ext4 defaults 0 0 mount -av

pvesm add lvm tv-taichi_data ???

mkdir -p /mnt/taichi_data
mkfs.ext4 /dev/vg-taichi/tv-taichi_data
mount /dev/vg-taichi/tv-taichi_data /mnt/taichi_data

nano /etc/fstab
/dev/mapper/vg--taichi-tv--taichi_data /mnt/taichi_data ext4 defaults 0 0
mount -av

These steps seem wrong.

Just create the thin LVM and then if you add it through the GUI in Datacenter -> Storage you can select the present but not configured LVMs that should be added as storage.

PVE will create logical volumes for the guests disks.

I agree with you. That's kind of my problem. At each step in the process I expected to see the volumes in the dashboard (or have the option to create something with them), but the disks/volumes were never available. The dashboard shows sdb, but nothing is in LVM or LVM-Thin.

I just went down my path hoping something would work. I was not expecting to need to mount the Volume either.

Thoughts? Thanks

...Shouldn't this have been enough?
sgdisk -N 1 /dev/sdb reboot pvcreate /dev/sdb1 vgcreate vg-taichi /dev/sdb1

Should I even need to do these through the console?
lvcreate -l 100%FREE --thinpool tp-taichi vg-taichi lvcreate -V 250G --thin -n tv-taichi_data vg-taichi/tp-taichi

So I started over. I installed PVE on a new drive (sdb) and I was able to see the and create VGs on the second drive (sda).
I hate asking this question, because the instructions are somewhere probably blatantly obvious the I am overlooking, but how do I add a thin storage on sda to house my VMs and LXCs?

Pointing to a good post or video, or article would be more than sufficient.

Nevermind. My steps were basically correct...
Find the drive name
fdisk -l

Partition the disk
sgdisk -N 1 /dev/sdb

reboot

Create a Physical Volume
pvcreate /dev/sdb1

Create Volume Group
vgcreate vg-taichi /dev/sdb

Create Thin Pool
lvcreate -l 100%FREE --thinpool tp-taichi vg-taichi

My error was where I went to add the LVM. I was trying to add it at the node level. Instead, go to
Dashboard->Datacenter->Storage->Add->LVM-Thin

Hopefully this helps someone else.

Oh, it so did help me!
Thanks for putting this up.
I ran into the exact same pitfall.

I to want to say thanks for posting the solution, though I was looking for the lvcreate steps.
