Description Justin Ross 2014-02-05 14:49:35 UTC

The bug content here was selected from bug 1061736:

 2] query vs. set functionality (expected backups)
  There is no way how to specify number of expected backups:
  * qpid-ha set --backups=2 consistently fails with UnknownMethod
   * note qpid-ha set --backups=0 do not fail - has simply no effect
  * qpid query always say None
  See Additional Info 2]
  I propose:
   * remove the expected backups functionality (if not useful/functional/needed)
        OR
   * valid values should not fail and should be reflected in qpid query table

Additional info:

Alan, please assess.

Comment 2 Alan Conway 2014-02-05 15:13:02 UTC

Well spotted, not sure what I was doing there but I didn't finish it. It doesn't make sense anyway as "expected backups" means something else (specific backup UUIDs, not just a count) in the new HA context.

Removed the invalid options on trunk:

Commit 1564797 from Alan Conway in branch 'qpid/trunk'
[ https://svn.apache.org/r1564797 ]

QPID-5541: HA incorrect options for expected-backups in qpid-ha tool

Remove invalid --backup option from qpid-ha set and query commands.

Comment 4 Frantisek Reznicek 2014-02-13 11:28:16 UTC

The not functional Expected backups HA feature was successfully removed.
qpid-ha set --backups is no longer valid option.
