New Revision: 1524774
URL: http://svn.apache.org/r1524774
Log:
VCL-727
Added additional looping to xCAT.pm::_rpower which makes additional attempts if
a timeout error is encountered. Added ability to control number of rpower
attempts via entries in the variable table: xcat|rpower_error_limit,
xcat|timeout_error_limit

> Project: VCL
> Issue Type: Improvement
> Components: vcld (backend)
> Affects Versions: 2.3.2
> Reporter: Andy Kurth

> Priority: Minor
> Fix For: 2.3.3
>
>
> xCAT commands run from the management node may occasionally display "Error:
> Timeout". This usually occurs when multiple nodes are being loaded and
> several xCAT commands are issued concurrently.
> Making additional attempts to run the command again usually results in the
> command succeeding. There are loops to detect errors and make multiple
> attempts in the current xCAT code but sometimes these are not sufficient. It
> would be beneficial to differentiate timeout errors from other errors. If a
> timeout error occurs, additional attempts should be made. The current loops
> are sufficient for non-timeout errors. If these occur multiple times in a
> row it usually means there is a problem which won't be fixed by trying over
> and over again. If timeout errors are encountered, more leeway should be
> given.
> This will help prevent some failed new and reload reservations.
