I'm glad you were able to restore the cluster @mjrepo2. Maybe you can find something interesting in this list. Regardless you can also use a different one. Are you sure you want to create this branch? To solve the issue we wanted to restore the backup. When restoring our etcd we have to keep the same deployment name (for connection strings and such), I have noticed when I try to restore a second time, upon helm delete etcd, my PVC for etcd-snapshotter is released, and will not be remounted, since a new PVC/PV for etcd-snapshotter is created.. Is this due to it being labelled as an "init-snapshot-volume" like so. While killing pods randomly, it all worked fine here. Check out our member new_member_envs. drwxrwsrwx 2 root root 4096 Jul 16 07:40 . except etcd. That's actually a very good point. i have the same issue. Our mission is to make awesome software available to everyone, everywhere. Why does etcd not release this mount after a successful restore, so I can delete the pv,pvc. This is certainly causing the error message (and unexpected behavior). I had 3 initially, and then I scaled down to 2 (still majority), but granted the third node managed to send member removing signal to all the other nodes (1, 2) it should not matter, right? Sep 2021, at 08:32, Roman Kuznetsov ***@***. Launch as many etcd instances as the number of nodes you wish to have in your cluster (in this example, three instances) and then perform the steps below on each node: Additional resources Documentation Improve this page by contributing to our documentation. @alemorcuq Is there a rough estimate when this will be worked on?

To sum up, I might have got my cluster into a weird state when scaling down to 0 pods while one of the pods was still in a crashloop. continuously updated when new versions are made available. There is no need for k8s API access to determine the list that goes in ETCD_INITIAL_CLUSTER, etcdctl would do: Using etcd-headless.kv.svc.cluster.local to drive the member list has the added benefit that etcdctl would retry by itself until it finds a node that is responsive (I'm thinking here of the situation when some of the nodes are not started or crash looping, still they resolve from the headless service DNS record). The libetcd.sh script covers for "Detected data from previous deployments", but you're left at the mercy of etcd's ability to cope with old data. Launch in Bitnami Launchpad.

Releases around helm/bitnami-aks/redis 9.3.3 on Artifact Hub. I'd rather start new nodes fresh and sync the latest data. I did some further investigation and was finally able to get the cluster up. Velero is an open source tool to safely backup and restore, perform disaster recovery, and migrate Kubernetes cluster resources and persistent volumes. That way when you scale-up, the nodes come with empty data instead of carrying artifacts from the previous run that could possibly mess-up the cluster state. Create the cluster. Now it gets funny, the etcd cluster builds up fine and everything is ok until every-day at 5:00 am, at this time the 3rd member of the cluster is leaving the cluster, the second node just stays fine. I can't seem to be able to reproduce this with a replicaCount of 5. Prerequisites To run this application you need Docker Engine >= 1.10.0. This method involves the following steps: Use the etcdctl tool to create a snapshot of the data in the source cluster.

Looking for a distributed and reliable key-value store? (See the logs below) Logs (etcd-0 node) helm install test -f etcd.yaml bitnami/etcd --set statefulset.replicaCount=3 --set persistence.enable=true --set persistence.size=8Gi --set startFromSnapshot.enabled=true --set startFromSnapshot.existingClaim=etcd-snapshotter --set startFromSnapshot.snapshotFilename=/snapshots/db-test. Or do I have to always provide another extra volume for that? It eventually fixed itself after 4 retries though, which is good. We periodically deploy changes via helm upgrade --install, and hence ETCD_INITIAL_CLUSTER_STATE also transitioned for us at some point from new to existing. Create the PV. Please remember to uninstall the previous release previously and remove the PVC(s) generated during the previous installation. Check this comment that does sth similar.

While there don't seem to be issues during regular operations, we have noticed significant flakiness when a member is terminated for any reason (e.g node draining, OOM killed) and is subsequently unable to rejoin the cluster with the exact same error message. Please create a pod like the one below, so you can inspect what you have in the "restore" PV: Then, access the Pod and inspect the volume: Please share the output of the above command. kubectl exec -it etcd-0 -- etcdctl snapshot restore /tmp/db --name etcd-0 --initial-cluster etcd-0=http://etcd-0.etcd-headless.default.svc.cluster.local:2380,etcd-1=http://etcd-1.etcd-headless.default.svc.cluster.local:2380,etcd-2=http://etcd-2.etcd-headless.default.svc.cluster.local:2380 --initial-cluster-token etcd-cluster-k8s --initial-advertise-peer-urls http://etcd-0.etcd-headless.default.svc.cluster.local:2380, COPY the restored data from /opt/bitnami/etcd/etcd-0.etcd/member/snap/db to the default data directory: /bitnami/etcd/data/member/snap/, Unfortunately it is not possible to change the data dir to the original restore location, because it contains the pod-id in the path: /opt/bitnami/etcd/etcd-0.etcd/member/snap/db.

Multi-Tier solutions are a perfect choice to ensure high availability and . I tested with the same procedure: randomly kill pods, wait for them to rejoin the cluster, kill one more, then wait again, scale down to 0 replicas, scale back up to 5 replicas. Falg to notify restore is to be performed. When updating the initialClusterState to "existing", the pod should rejoin the cluster and be able to recover from pod crash.

Now, etcd makes use of these env vars only to start a new member after that member has been added to the existing cluster. If the user has lost nodes, they must recreate all the non-recovery control plane machines and then run '-p' option from this plugin to redeploy ETCD. I have just raised the internal priority of this issue. I also tried building docker image based on mentioned PR - it does not generate an event that says that pre-stop failed when scaling down, but it does not help re-joining the cluster when scaling up unfortunately. That happens because there are container env var changes: ETCD_INITIAL_CLUSTER_STATE changes from new -> existing Cannot retrieve contributors at this time. Use Helm v3 with the chart. It seems overkill that I have a volume for each etcd instance, a volume to snapshot the cluster, and another volume to restore?
