Dmitri Chebotarov commented on VCL-609:
---------------------------------------
Andy, I think you are referring to this error:
|image|DataStructure.pm:get_computer_private_ip_address(1589)|failed to cat
/etc/hosts on this management node, exit status: 255, output:
Last time I got this error it was caused by non-0 return status while executing
SSH command during reservation. In my case it was:
new|utils.pm:run_ssh_command(5481)|SSH command executed on vmguest-vcl91,
returning (0, "The following error occurred: ...")
It didn't triggered a warning or error during the reservation process, but I
think the non-0 return code is "passed" to get_computer_private_ip_address
subroutine, which triggers the error/failure above, but there is nothing wrong
with the 'cat /etc/hosts'.
> Reservations fail if cat command returns non-zero exit status when retrieving
> contents of /etc/hosts on management node

> The get_computer_private_ip_address subroutine in Datastructure.pm retrieves
> the contents of /etc/hosts on the management node using the cat command.
> Occasionally this command returns a non-zero exit status even though the
> contents were retrieved causing the subroutine to return null unnecessarily.
