where do you see the iscsi attached storage

[webservio]

Excuse my ignorance on this question. Where do I see the iscsi attached storage? I added a test iscsi target call test and directly attached to LUN without any problems. However in backup or even in the system I cannot locate the storage. Before posting I read the Storage Model:

http://pve.proxmox.com/wiki/Storage_Model

But still not sure how to access the iscsi attached storage .

Thanks in advance.

Hi,
when you add a LVM-Group on the storage, you see this vg in the storage-menu.
Later, the disks from the VMs are created as logical volumes on this volume group.

I am sorry UDO but I do understand what you meant.

Hi,
some month ago i had the effect, that i don't see a SAN-Partition. I think it's had something to do with the installed multipath.
But i create the volumegroup on the console and add them in the frontend.

UDO,

Did you iscsi based Volume group show in df command? Below is an example of a NFS mounted (using openfiler NAS) in df command. However I cannot create something like that using iscsi:

vpshost2-36:~# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/pve/root 38188544 3108648 33140032 9% /

Hi,
the lvm-groups are not displayed with df, because they are not mountet, nor they have a filesystem - it's space for logical volumes. The logical volumes on the other hand are container like a true harddisk - in the container the guest-vm wrote the filesystem (ext, or ntfs, or what else).

To get a overview, you can use the commands

pvdisplay
vgdisplay
lvdisplay

pv - device. vg - volume group. lv logical volume

You can look at /etc/pve/storage.cfg

as example one vg from storage.cfg:

lvm: vg_ams200_fc_1
    vgname ams200_fc_1_vg
    shared
    content images

vgdisplay ams200_fc_1_vg
  --- Volume group ---
  VG Name               ams200_fc_1_vg
  System ID             
  Format                lvm2
  Metadata Areas        1
  Metadata Sequence No  255
  VG Access             read/write
  VG Status             resizable
  MAX LV                0
  Cur LV                14
  Open LV               4
  Max PV                0
  Cur PV                1
  Act PV                1
  VG Size               132,82 GB
  PE Size               4,00 MB
  Total PE              34002
  Alloc PE / Size       28084 / 109,70 GB
  Free  PE / Size       5918 / 23,12 GB
  VG UUID               fosNqB-YjAB-8g49-3FXc-nEav-mlUJ-eA91Hc

But i have no iscsi - my external storage are fibre channel.
