Now that the current generation of dumps is running from Airflow and Kubernetes, we can re-purpose the previous bare-metal servers.
The following two servers are EoL and should be decommissioned:
- dumpsdata1003
- snapshot1010
The remaining snapshot servers (https://wikitech.wikimedia.org/wiki/Dumps/Snapshot_hosts) will likely make good dse-k8s-worker nodes, since they have relatively powerful CPUs, although only 64 GB of RAM each.
The snapshot servers have been renamed and re-commissioned like this.
- snapshot1011 -> dse-k8s-worker1015
- snapshot1012 -> dse-k8s-worker1016
- snapshot1013 -> dse-k8s-worker1017
- snapshot1015 -> dse-k8s-worker1018
- snapshot1016 -> dse-k8s-worker1019
The dumpsdata servers are to be renamed and recommissioned like this:
- dumpsdata1004 -> an-worker1233
- dumpsdata1005 -> an-worker1234
- dumpsdata1006 -> an-worker1235
- dumpsdata1007 -> an-worker1236
The dumpsdata servers (https://wikitech.wikimedia.org/wiki/Dumps/Dumpsdata_hosts) have lower-spec CPU and are 2U servers with 12 x 4TB disks each.
These are a little under-specced as either Hadoop or dse-k8s workers, but we might be able to find a role for them, or we could simply mark them as spare for DC-Ops to allocate accordingly.
