I am learning k8s and had an exercise to backup etcd data, so I used the command:
ETCDCTL_API=3 etcdctl snapshot save --endpoints localhost:2379 --cacert=/etc/kubernetes/pki/etcd/ca.crt --cert=/etc/kubernetes/pki/etcd/server.crt --key=/etc/kubernetes/pki/etcd/server.key mysnap.db
which worked nicely :) but then when I tried to get the snapshot status with:
ETCDCTL_API=3 etcdctl snapshot status mysnap.db
and with:
ETCDCTL_API=3 etcdctl snapshot status --endpoints localhost:2379 --cacert=/etc/kubernetes/pki/etcd/ca.crt --cert=/etc/kubernetes/pki/etcd/server.crt --key=/etc/kubernetes/pki/etcd/server.key mysnap.db
in both situations I got the error message:
Error: cannot get hash of bucket �_
I tried to understand why but did not find out a lot, only the section of the source code where the error message jump from (in golang) in this URL: https://fossies.org/linux/etcd/clientv3/snapshot/v3_snapshot.go
etcdctl version: 3.2.26
