https://kubernetes.io/docs/tutorials/stateful-application/basic-stateful-set/#updating-statefulsets

There are some cases that you might be trying to update a statefulset and you get this error:

Error: cannot patch "my-statefulset" with kind StatefulSet: StatefulSet.apps "my-statefulset" is invalid: spec: Forbidden: updates to statefulset spec for fields other than 'replicas', 'ordinals', 'template', 'updateStrategy', 'persistentVolumeClaimRetentionPolicy' and 'minReadySeconds' are forbidden && cannot patch "my-statefulset-tracking" with kind StatefulSet: StatefulSet.apps "my-statefulset-tracking" is invalid: spec: Forbidden: updates to statefulset spec for fields other than 'replicas', 'ordinals', 'template', 'updateStrategy', 'persistentVolumeClaimRetentionPolicy' and 'minReadySeconds' are forbidden

And while you can diff a file manually beteween you update and the yaml that you can fecth: kubectl -n my-ns get sts my-statefulset -o yaml

HP Smart Storage Admin CLI (ssacli) installation and usage on Proxmox PVE (6.x)

Why use HP Smart Storage Admin CLI?

You can use ssacli (smart storage administrator command line interface) tool to manage any of supported HP Smart Array Controllers in your Proxmox host without need to reboot your server to access Smart Storage Administrator in BIOS. That means no host downtime when managing your storage.

CLI is not as convenient as GUI interface provided by BIOS or desktop utilities, but still allows you to fully manage your controller, physical disks and logical drives on the fly with no Proxmox host downtime.

ssacli replaces older hpssacli, but shares the same syntax and adds support for newer servers and controllers.

Adding tailscale to an EdgeRouter (and surviving system upgrades)

I suggest you run sudo bash on all of these so you're the root user.

Installing

1. Download tailscale and put the files in /config/. Find the latest stable or unstable version for your EdgeRouter's processor (ex. ER4 is mips and ERX is mipself)

sudo bash    # if you havent already

Setup etcdctl using the instructions at https://github.com/etcd-io/etcd/releases/tag/v3.4.13 (changed path to /usr/local/bin):

Note: if you want to match th etcdctl binaries with the embedded k3s etcd version, please run the curl command for getting the version first and adjust ETCD_VER below accordingly:

curl -L --cacert /var/lib/rancher/k3s/server/tls/etcd/server-ca.crt --cert /var/lib/rancher/k3s/server/tls/etcd/server-client.crt --key /var/lib/rancher/k3s/server/tls/etcd/server-client.key https://127.0.0.1:2379/version
