Add VLAN ... Error: Unknown device type.

[tcabernoch]

I work in a VLAN controlled environment.
The first thing I do to a newly installed host is put it on our MGT VLAN, so I can talk to it.
I add an interface, give it an IP, bring it up, and set the default route. Bam. Its online.

ip link add link eno1 name eno1.10 type vlan id 10


Or, that's they way it used to work. Fresh install ... proxmox-backup-server_3.3-1.iso
Now I when I add a VLAN interface, I get "Error: Unknown device type."

If I can't get this online from an ad hoc interface, I'm going to have to manually type out the whole vlan-aware bridge config in an iDRAC console session.
That sorta sux. :[

...
I've reinstalled with proxmox-backup-server_3.2-1.iso. Same issue.
I use this process a lot when I build PVE servers. Really baffled. Am I doing something wrong?

Hi,

just tried it out on a fresh installation of PBS ISO 3.3-1 and 3.4-1 - that command / creation of the VLAN interface worked fine for me on both systems.

Can you try with 3.4-1?
Maybe also verify the checksums of the ISOs, or run apt update && apt install -y debsums && debsums -c on the affected systems, see if anything is corrupted.

HI there. Thank you very much for your reply. I don't have the problem to poke at anymore. Another admin fixed it. This is what he said.

"something happened with the rebuild and there were a bunch of modules missing, one of which was bonding."

Yes. I should probably checksum the ISOs I used. I need to understand how this took place.

... And now that I think about it, every single time I've advised somebody about an issue of this sort, its always been a bad download.
Search me, how this one ISO out of all those ISOs out there manages to create a fully bootable and functional system that's just 'missing' a few parts.
Weird. Very strange.
