Problem adding an extra local storage in VE 5.2

[lucentsound]

Hi All,
i’m a newbie about Proxmox and i ask you for an help about the starting configuration.

I installed VE 5.2 on one HDD of a Server so SDA is the drive where Proxmox installation is running.

Then i add a second HDD locally on the same Server for storage purposes, SDB, and followed these commands i found on a blog:

fdisk –l (to see the name of new drive)

cfdisk /dev/sdb

and create new, primary, partition.

Then

pvcreate /dev/sdb1

Created a volume group for example "Data-Storage"

vgcreate Data-Storage /dev/sdb1


Then Added the storage in ProxMox webinterface



- clicked on tab Storage.

- clicked Add – LVM Group

- typed an ID Name Data-Storage

- Base Storage: Existing Volume Groups

- Volume Group: Data-Storage



- Enabled: Checked

Now the problem is that under menu : pve – Data Storage (pve) – Content i can’t upload any image cause the button is gray.

I added some screenshoot.

I know the question is stupid but please help me to under stand the mistake.

Thanks to all in advance.

Are you trying to upload ISO images? LVM is a block level storage. I dont believe you can store any ISO or LXC templates on block storage. You should mount the drive in a directory and add it to Pmx as Local storage instead of LVM. You can still have LVM on the actual drive, just need to mount it.

Yes Ahmed, i would like to use this second disk to upload ISO and also to contain virtual machine. Can you indicate me the steps i should make to reconfigure the disk? Thank you

The process is very simple. You do not need to reconfigure the drive itself.

This needs to be done from Command line:
1. Create an empty directory with any name. For example,
# mkdir /mnt/lvmdata

2. Run the command lvdisplay to get the exact name of the LVM you created. It should be in the following format:
/dev/volume_group_name/logical_volume_name

3. Add the following line into /etc/fstab so the node mounts the directory automatically after a reboot. I am assuming you used ext4 as to create filesystem.
/dev/mapper/logival_volume_name /mnt/lvmdata ext4 defaults 0 0

This needs to be done from GUI:
4. Goto Datacenter > Storage > Add > Directory

5. In the directory box type in: /mnt/lvmdata and click Add

Now you can select any Content type.

Hi, thank you very much for your precious support.
As you suggested me i investigated first the LVM i created and there is something i don't understand.
If i run the command pvscan i get:

root@pve:/# pvscan
PV /dev/sdb1 VG Data-Storage lvm2 [278.87 GiB / 278.87 GiB free]
PV /dev/sda3 VG pve lvm2 [135.87 GiB / 16.00 GiB free]
Total: 2 [414.74 GiB] / in use: 2 [414.74 GiB] / in no VG: 0 [0 ]
root@pve:/#

So it seams to me i created a volume group named "Data-Storage" on a physical volume /dev/sdb1 of 278.87 GiB free ( the new disk i added is a 300 Gib)

But if i run the command lvdisplay i get:

root@pve:/# lvdisplay

So, it seams i can't see the 278.87 GiB free that hoped to create. Where am i wrong?
