[SOLVED] Changed node IP and it is now giving a No route to host (595) error.

[NotLarry]

We had to migrate one of our nodes (9 in total) to a new subnet. It's internal network stays the same.
We migrated 6 other nodes in the past with no issues.

After the ip change (vlan on the switch and in /etc/network/interfaces on the node)

No changes were made to corosync.conf (the ip addresses are not on the interface that changed)
No changes were made to /etc/hosts (again, no interfaces in the /etc/hosts file were changed).

/etc/pve is empty and trying to start pve-cluster results in a failure with the following error;

hvcms01pri pveproxy[3825]: /etc/pve/local/pve-ssl.key: failed to load local private key (key_file or key) at /usr/share/perl5/PVE/APIServer/AnyEvent.pm line 1687

/etc/pve is empty and trying to start pve-cluster results in a failure with the following error;

seems like corosync is not running or the node cannot see the others (is not quorate) - check the journal for messages from corosync

I hope this helps!

<solved>

Did the following;
systemctl stop pve-cluster
systemctl stop corosync
moved /etc/pve to a temporary file
mkdir /etc/pve
/sbin/shutdown -r now

System came back
