* ctdb-freeze: Drop function thaw_priority()Amitay Isaacs2016-07-251-16/+10
| | | | | | | | | There are no database priorities anymore, so the function name does not make any sense. Call the code in thaw_priority() directly from ctdb_control_thaw(). Signed-off-by: Amitay Isaacs <amitay@gmail.com> Reviewed-by: Martin Schwenke <martin@meltin.net>
* ctdb-daemon: Drop priorites from freeze/thaw codeAmitay Isaacs2016-07-251-90/+47
| | | | | | | | | | | Parallel database recovery freezes databases in parallel and irrespective of database priority. So drop priority from freeze/thaw code. Database priority will be dropped completely soon. Now FREEZE and THAW controls operate on all the databases.

| | | | | | | | | | | It's possible that the databases can get attached after initial freeze.

* freeze: If priority is invalid here, it's time to abortAmitay Isaacs2013-07-021-6/+1

Other callers of ctdb_start_freeze() are internal to CTDB. So if priority is invalid in ctdb_start_freeze(), definitely something is seriously wrong.
