External Storage Configuration

[kiwito]

Hi,

I decide to try proxmox. I installed Proxmox VE 6.2. When i click on "nodes-->myserver-->disks--> " I can see my external storage there. But it has 6 different name.

/dev/sdc
/dev/sde and goes on.

I checked them from CLI as blkid and they all have same id. I need to map them to storage.

How can i do that? My external storage model is NGX-IO_ISCSI . I am looking for solution for 2 days. I dont have much knowledge i hope u can understand my problem

Thank you.

Hey,

could you post the output of lsblk. Do you have data on them? I assume you have multiple drives and you would like to add them as one big, the easiest way to achieve that is probably by using LVM.

1. pvcreate /dev/sda /dev/sdb /dev/sdc ...
2. vgcreate <volume_group_name> /dev/sda /dev/sdb /dev/sdc ... create a volumegroup
3. lvcreate -n <logical_volume_name> -l100%FREE <volume_group_name> create one logical volume on the volumegroup

Now you can add the created logical volume to proxmox. LVM offers a lot of functionality I recommend to take a look at https://www.digitalocean.com/commun...on-to-lvm-concepts-terminology-and-operations for a short overview.

EDIT: make sure you have lvm2 installed

You need to have multipath installed and configured so that it maps all possible paths to one device, which then can be used as @Hannes Laimer (ui, new Proxmox staff member? Welcome!) explained.

Yeah i was looking for that.
Multipath is done.

But after pvcreate command i get the response Device /dev/dm-7 excluded by filter.

I looked google. May it be because of the size? Because i have 2 storage one 12 TB the other one 8 TB.
