TASK ERROR: unable to create VM 104 - no such volume group 'drive2'

[zoltanb]

Hello,

I am new to ProxMox and currently testing it in my local environment with 3 nodes: i3, msi and smhome.

Under Datacenter / Storage I added a new LVM (drive2) which is physically attached to "i3" node but it is also shared with my 2 other nodes: "msi" and "smhome".
When I want to create a new VM, I can do it without any issue on the "i3" node, but not on "smhome" node.
For some reason, "smhome" node reports drive2 as 0 b available 0 b capacity although it let me select it, but the VM is not created, this is the error message I receive:

"Command failed with status code 5.
command '/sbin/vgscan --ignorelockingfailure --mknodes' failed: exit code 5
TASK ERROR: unable to create VM 104 - no such volume group 'drive2'"

This is what I see on i3 node:

root@i3:~# pvs
PV VG Fmt Attr PSize PFree
/dev/sda2 drive2 lvm2 a-- <2.73t <2.70t
/dev/sdb3 pve lvm2 a-- <223.07g <16.00g

And this is what I see on smhome node:

root@smhome:~# pvs
PV VG Fmt Attr PSize PFree
/dev/sda2 centos lvm2 a-- <297.09g 4.00m
/dev/sdb3 pve lvm2 a-- <223.07g 15.99g

centos 1 3 0 wz--n- <297.09g 4.00m
pve 1 3 0 wz--n- <223.07g 15.99g

What am I doing wrong? Why do I see the LVM on web interface (attached) but I can't use it to create a VM?

Thank you in advance.

I checked under storage and this is what I see under "i3":

Enabled Yes

Active Yes

Content Disk image, Container

Type LVM

Usage 0.00% (0 B of 3.00 TB)


Under "smhome", I see it as Active No and usage NA.

Enabled Yes

Active No

Content Disk image, Container

Type LVM

Usage NA

Hi,
the grey question mark means that Proxmox VE wasn't able to find the storage. Proxmox VE is not able to automatically share your LVM storage to other nodes. If you need that, you need to set it up yourself. Otherwise, you should adapt your storage configuration and restrict the storage to the nodes where it actually is available.

Thanks Fabian. I thought so, but it was strange that I could select the drive of another node on the web GUI.
