Known Causes

4 known causes
⚠️
SSH Key Misconfiguration
Public and private SSH keys may not be correctly generated, distributed, or properly referenced by the ACFS configuration on all cluster nodes.
⚠️
File Permissions Error
The `.ssh` directory or the SSH key files (`id_rsa`, `authorized_keys`) might have incorrect file permissions or ownership, preventing SSH from accessing them securely.
⚠️
Hostname Resolution Failure
The cluster nodes might not be able to resolve each other's hostnames or IP addresses correctly, hindering the establishment of SSH connections.
⚠️
SSH Daemon Issues
The SSH daemon (`sshd`) might not be running on one or more target nodes, or its configuration (`sshd_config`) might be preventing passwordless access.
