We are trying to set up a Vertica backup using vbr.py.
We are trying to set up a Vertica copycluster using vbr.py.
We have validated that the dradmin user has passwordless ssh enabled and working.
The backups fail with this message:
[[email protected] backup]$ /opt/vertica/bin/vbr.py --task backup --config-file /home/dradmin/backup/backup_snapshot.ini
Error: Errors connecting to remote hosts: <IP>. Check SSH settings, and that the same Vertica version is installed on all nodes.
Since Vertica (7.2.x), it is required that you set AllowTcpForwarding to yes in the /etc/ssh/sshd_config.
All supported releases
Notice that by default it is commented out, that is because the default value is yes, if it has been edited of changed, change it back.
Match User dradmin
Note, if you edit this file, recycle sshd
systemctl restart sshd
