Over the past updates (espcially the update to
etcd-wrapper: https://github.com/coreos/coreos-overlay/tree/master/app-admin/etcd-wrapper) my etcd-cluster with five machines broke. Now I'm trying to recover from that.
Currently I only use it for the
etcd-lock while updating the machines. So there is basically no important information in there (yet).
I tried a lot of stuff and since, in my opinion, the documentation is not that structured, I mixed a lot of infos form different parts together. Currently I'm in a state, where one node wants to elect a leader with another node. But that other node thinks it is part of another cluster. And I cannot do anything on the first one anymore.
etcdctl just revokes all actions with the info, that the cluster is not healthy...
So I want to do a fresh start again!
Could someone point me to some part of the documentation, that explains that? It seems, that the disaster recovery part (https://coreos.com/etcd/docs/latest/op-guide/recovery.html), that allegedly contained the info, has changed (and is also depreacted).
Additionally it would be really helpful, if someone could point me to the part of the docu, that explains how to setup a
etcd-cluster without re-installing the whole system.
Thanks in advance!
PS: I would have gladly selected some better tags (like
etcd-cluster), but I am not allowed to create them now :)
