What do you get if  you run the following command on the console

# pvs /dev/disk/by-id/scsi-360a980004335444e4e6f544657306a39

Subject: [PVE-User] Problems adding iSCSI LVM target

Hi.

Since a few months using proxmox with local disks we're trying to implement it over an iSCSI target but we have problems to make the LVM volume over the target.

These are the steps we follow:

- From the web interface: Storage -> Storage List -> Add iSCSI target
- Fill all the data needed, and proxmox see the target:
nas1

ISCSI

Yes

Yes

Yes

n/a

n/a

n/a


- From the Storage List menu, "Add LVM group" and fill the Storage Name (tried to fill it with the same name than the target or with other), select the base storage, which then shows the base volume filled up with the existing iSCSI LUN, filled de volume group name (=pve), enable, shared and content "Virtual Disks".

But when press de "save" link, proxmox shows a pop-up with this info:

Error: command '/sbin/pvs --separator : --noheadings --units k --unbuffered --nosuffix --options pv_name,pv_size,vg_name,pv_uuid /dev/disk/by-id/scsi-360a980004335444e4e6f544657306a39' failed with exit code 5

This is the syslog output:
