- Why is na-arc-5 using qdisc pfifo_fast for eth0 while all the other na-arc nodes are using qdisc fq_codel for eth0? (see ip addr)
- na-arc-5 is running the rh-downloader service so its interface would affect all downloads.
- Should we change it to match with something like tc qdisc replace dev eth0 root fq_codel
- Is putting all the 1Gb/s production docker swarm nodes on the same ASIC on the same Fabric Extender of the cv-nexus switch a good idea?
- I am thinking it does not matter because it looks like the production docker swarm nodes use the 10Gb/s network which is on cv-nexus9k
- Why does natest-arc-3 have ens3 instead of eth0 and why is its speed 100Mb/s?
- virsh domiflist natest-arc-3 shows the Model as rtl8139 instead of virtio
- When I run ethtool eth0 on nar-arc-{1..5} natest-arc-{1..2} as root, the result is just Link detected: yes instead of the full report with speed while na-arc-3 shows 100Mb/s.
- Can we set up a test archive query that uses the "other" docker swarm which in this case would be the production swarm (na-arc-*)?
- Is putting the production swarm nodes (na-arc-*) on the 10Gb/s network a good idea? Sure it makes a fast connection to cvsan but it adds one more hop to the nangas servers (e.g. na-arc-1 -> cv-nexus9k -> cv-nexus -> nangas14)
- Why are there VLANs on the VM hosts. e.g. em1.97 on naasc-vs-4?
2022-08-12 dhart: If you want all of your guest VMs to be on the same subnet as the VM host, then VLAN awareness isn't needed. However, in most cases we want the flexibility of being able to have VM guests on different networks (from one another and/or the VM host) so the VM host is configured with a trunk interface to the network to allow for any VLAN to be passed to the underlying VM guests housed on that VM host machine
- 2022-08-12 dhart: 10.2.97.x (and 10.2.96.x) = internal VLAN for servers (primarily) 10.2.99.x = internal VLAN for server management 10.2.120.x = internal VLAN for 10 GE connections
- When I connect to the container acralmaprod001.azurecr.io/offline-production/rh-download:2022.06.01.2022jun I get errors like unknown user 1009
- Can we put 10Gb/s NICs in the nangas nodes?
- Why does almaportal use ens3 while almascience uses eth0?
