* Dimension "bandwidth exceeded" exhausted on 1 nodes

[aep]

Nomad version

Nomad v0.10.4 (f750636)

Operating system and Environment details

archlinux.

Issue

there appears to be no way to set network_speed or at least ignore it if the interface is not the public interface (which i need to set, otherwise nomad announced the wrong address internally to consul)

unclear if network_speed is ignored because nomad node-status --verbose does not show any network resources, so there is no way to know why it is exhausted either, since no jobs require any network resources

Reproduction steps

client {
network_interface = "wireguard"
network_speed = 1000
}

launch any job without network resource constrains

###logs

2020-03-20T23:21:38.091+0100 [DEBUG] client.fingerprint_mgr.network: unable to read link speed: path=/sys/class/net/cluster/speed

so apparently not ignored. still cant launch anything, even tho no jobs require network resources

i dont understand why, but rebooting the server (rather than the client where this is failing) made the problem go away

Hi @aep Thanks for reporting the bug and sorry for the slowness. This seems very similar to #7232 that I'm investigating this week.

FWIW, i can't reproduce it. I think this might happen when you start without network_interface, then change it later. possibly the old value is cached somewhere.
