Retire m class VMs #24

Open tdudgeon opened 3 years ago

tdudgeon commented 3 years ago

The m class hypervisors are starting to be removed so we must replace the VMs with c class ones. Seems like we have the following ones:

DLS project pulsar-central-manager.xchem (m2.large) pulsar-bastion-2 (m1.small)

xchem-follow-up project xch-ctrl1 (m1.xlarge) xch-etcd1 (m1.large) kubernetes-nfs-fs-media (m1.large) xch-production-etcd1/2/3 (m1.large) xch-production-ctrl1/2 (m1.large) rke-etcd-1/2/3 (m1.large)

Seems like the instances can just be resized to c-class instances. Jacob says this is the recommended approach, but best first to create a snapshot just in case.

I did a quick test and it worked fine with an ubuntu VM, but I'm having problems creating centos7 ones ATM so can't test that.

pulsar-bastion-2 was resized to a c2.small instance.

tdudgeon commented 3 years ago

rke-etcd-1/2/3 have been resized to c1.large instances.

tdudgeon commented 3 years ago

pulsar-central-manager.xchem has been resized to a c2.large instance.

Only the xch-production-etcd1/2/3 and xch-production-ctrl1/2 instances remain and those will be handled as part of the prod K8S cluster upgrade.
