Andy Kurth created VCL-727:
------------------------------
Summary: xCAT commands may timeout - make multiple attempts
Key: VCL-727
URL: https://issues.apache.org/jira/browse/VCL-727
Project: VCL
Issue Type: Improvement
Components: vcld (backend)
Affects Versions: 2.3.2
Reporter: Andy Kurth
Assignee: 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.
