[SOLVED] iSCSI share from Proxmox

[rcd]

How can i configure Proxmox to share an iSCSI (or other block level share) to be mounted on a PC)?
I can only find descriptions for mounting iSCSI shares exported from other servers onto Proxmox.

Sure, it's Debian-based, so you can use any software package that is available in Debian to achieve your goal.

Thanks, but I meant built-into Proxmox, kinda like in FreeNAS. I guess not?

No, Proxmox VE is a virtualization platform, not a NAS software. Just go the Debian way.

Uh, another rabbithole ...

The Debian page is quite limited. I found a better guide on Server World. Still, after installing, trying to run targetcli i get this error:

b"modprobe: ERROR: ../libkmod/libkmod.c:586 kmod_search_moddep() could not open moddep file '/lib/modules/5.4.41-1-pve/modules.dep.bin'\nmodprobe: FATAL: Module target_core_mod not found in directory /lib/modules/5.4.41-1-pve\n"
root@nas:/data#

I'm guessing this means it won't run in a CT, so is there a best practice for this? Run it on the host? I'd rather not have to start yet another VM for this.

What about Ceph? It seems to also be some way of providing clustered block-level storage? Could it be used as a newer version of iSCSI?

No, CEPH is distributed shared storage, whereas iSCSI is exporting storage from one endpoint and providing dedicated shared storage.

Of course on the host. Targetcli-fb works fine directly on the PVE host, @fireon has also written a german howto.

Ok, I just thought it was generally discouraged to run services on the host.

That depends on what you want to share. If you e.g. want to share ZFS via NFS, Samba, iSCSI or FC, you need to have it on your host. It'll also yield the best performance.
You can however do everything inside of a VM (not CT), but that depends also on the use case.

Ok, installed on the host using the guide mentioned earlier works fine.
