Restore one cluster node

[mac-linux-free]

Hello, due to the grub/zfs non efi bug encountered now with pm 8.1 upgrade I have to reinstall one node after the other. Does the restore process work on a member node?

Thank you.

Hello!

As said in the readme, this has not been tested in a cluster configuration. As far as i know, it should work on the host, but i'm not sure how the cluster may react.

Please let me know how it goes if you try, very interested!

Hello!

I got it working. But please could you add one more thing to the backup?

/etc/corosync/authkey it is a file.

It did not work at first. But after copying this file my cluster is up again.

Horray.

but the ssh_keys are messed up

and you have to be sure, that replication jobs are removed at first.

How so? Is there something we can do about it? Prevent any unwanted behaviors

Ye makes sense, that's the kind of things i was exepecting when i say " i'm not sure how the cluster may react" :)

So in cluster configurations, you have to stop the replication in cluster before restoring the memeber configuration right?

In the next hour I'll do the next node. So thank you.
