Error in "Storage Model" Wiki?

[maurizio.omissoni]

Hello
i tryed this part of the "Storage Model" Wiki in
http://pve.proxmox.com/wiki/Storage_Model

<part of Wiki>
Use local devices (like /dev/sd../, FC)

Before you can use local devices for storing VM´s you need to configure LVM2 for these devices on the console first.
This is a three step procedure (I just plugged in a 8 GB USB Stick for demonstration, recognized as /dev/sdl on my box)
First create the physical volume:
proxmox-ve:~# pvcreate /dev/sdl1
Physical volume "/dev/sdl1" successfully created
proxmox-ve:~#Second, create the volume group:
proxmox-ve:~# vgcreate usb-stick /dev/sdl1
Volume group "usb-stick" successfully created
proxmox-ve:~#And finally: Add the LVM Group to the storage list via the web interface.

after having installed a PVE 1.4, i installed a sata 80G HD with only one ext3 partition /dev/sdb1

First two steps were successful, but the third with the webgui gives me:

Error: unable to parse value for 'vgname'

I have looked for that error in the forum but i did not find any solution.
Strangely, with an usb-stick it works

Error: unable to parse value for 'vgname'

You select 'Use existing volumes' and the volume group 'usb-stick' is listed?

 

[maurizio.omissoni]

yes, "usb" and "80G" is listed. but only "80G" gives the error.
Is it important, that i added the physical HD after having installed PVE 1.4?

 

[dietmar]

yes, "usb" and "80G" is listed.

I thought the VG is named ''usb-stick'? Maybe we have a bug here - please try to use a name without hyphen for the VG.

 

[dietmar]

yes, "usb" and "80G" is listed. but only "80G" gives the error.

I am finally confused - what are the names of your volume groups? Please can you post the output of:

# vgs

unfortunately, i cannot start vgs as in the meanwhile i am in italy, and have no access to my server.

But as i wrote, i used the name "80G" for the 80GB Harddisk-partition /dev/sdb1, and "usb" for the stick at /dev/sdc1. no hyphens were used.
bothe names appears on the list in the webgui. I can create a LVM Group with "usb", but with "80G" I get that error.

Ah, OK - I think the name '80G' is the problem, because it does not start with a letter - please can you test with another name (starting with a letter)?

Yes, allready tryed this, when i use only numbers, e.g. "103" than appears the error "invalig character", but "80G" is accepted, I tryed also other pure alphabetic names as "abc" but the parse error still comes

Thank you Dietmar
now with the name "G80" it works!
