Issue

  • We are trying to install the undercloud with the below undercloud.conf file parameters and were facing the below issue. On making the changes on the undercloud.py file the undercloud installation was successful.
local_ip = 192.168.15.10/24
undercloud_public_host = 192.168.15.11
undercloud_admin_host = 192.168.15.12
undercloud_nameservers = 10.135.2.13
overcloud_domain_name = localdomain
local_interface = ens224
masquerade_network = 192.168.15.0/24
generate_service_certificate = false
undercloud_ntp_servers = 10.135.2.13
undercloud_hostname = vm-os-dir.localdomain
clean_nodes = true
overcloud_domain_name = localdomain
enable_ui = true
  • We have also enabled SeLinux to Enforcing mode:
 [stack@vm-os-dir ~]$ getenforce

Undercloud install failed.

Reason: Command '['find', '/home/stack/.ssh', '-exec', 'ls', '-lZ', '{}', ';']' returned non-zero exit status 1

See the previous output for details about what went wrong.  The full install
log can be found at /home/stack/.instack/install-undercloud.log.

#############################################################################
  • We made the changes on the undercloud.py file on line: 1730 to get the undercloud installation successfully running:
 ['find', ssh_path, '-exec', 'ls', '-lZa', '{}', ';']) 

where we added an 'a' for -lZ as it was not getting the .ssh directory.

  • After fixing that line we were able to install the undercloud successfully:
2020-01-22 11:14:36,658 INFO:
#############################################################################
Undercloud install complete.

The file containing this installation's passwords is at
/home/stack/undercloud-passwords.conf.

There is also a stackrc file at /home/stack/stackrc.

These files are needed to interact with the OpenStack services, and should be
secured.
