Hey guys, I have trouble while trying to take snapshot from etcd in my Kubernetes cluster. There hasn't been any resource in order to fix this problem on rke issue (on Github). Whenever I run

rke etcd snapshot-save --config cluster.yml --name first-snapshot

command, I face the following issue:

invalid memory address or nil pointer

This error has been solved but I can't find the snapshot (it's name in the above case is first-snapshot) in my files.

find / -name first-snapshot 2>/dev/null

The above command didn't find any file on my computer.

The snapshot should be in

/opt

the file will have the date appended to it so the reason the find command didn't work is because there won't be a literal file called 'first-snapshot' I would use a wildcard (*) in the find command to find it so like:

find / -name "first-snapshot*" 2>/dev/null

Thanks

That could be a lot of things. it could be RKE. It could be your OS. It could be the OS you're running rke snapshot-save from. More context is needed here. this is a very generic memory error...
