Andy Kurth updated VCL-836:
---------------------------
Summary: Incorrect IP addresses in cluster_info file (was: cluster_info
file may contain incorrect IP addresses)
> Incorrect IP addresses in cluster_info file
> -------------------------------------------
>
> Key: VCL-836
> URL: https://issues.apache.org/jira/browse/VCL-836
> Project: VCL
> Issue Type: Bug
> Components: vcld (backend)
> Affects Versions: 2.4
> Reporter: Andy Kurth
> Assignee: Andy Kurth
> Fix For: 2.4.1
>
>
> The cluster_info file added to computers in a cluster reservation may contain
> wrong public IP addresses. This is due to the backend vcld daemon caching
> reservation data including the computer public IP address in its %ENV
> variable.
> A computer using dynamic DHCP may obtain a different IP address when loaded.
> The IP address in the VCL database prior to the computer being loaded is
> retrieved when the load (new or reload state) process begins. After the
> computer is loaded, its correct public IP address is retrieved from the
> computer's OS and the database is updated.
> The problem occurs when subsequent processes are forked -- mainly when a
> request goes from new to reserved. After the new process terminates, the
> vcld daemon is still storing the original computer information in %ENV. A
> reserved process is forked which uses this data. During reserved,
> cluster_info is created which contains the public IP address of each computer
> assigned to the request. When cluster_info is created, the previously
> retrieved data is used. As a result, the only IP addresses which would be
> correct are the ones which haven't changed since vcld originally retrieved
> the data.
