This is the latest stable release of CTDB. CTDB 2.5.4 can be used with
Samba releases 3.6.x, 4.0.x and 4.1.x.
Changes in CTDB 2.5.4
=====================
User-visible changes
--------------------
* New command "ctdb detach" to detach a database.
* Support for TDB robust mutexes. To enable set TDBMutexEnabled=1.
The setting is per node.
* New manual page ctdb-statistics.7.
Important bug fixes
-------------------
* Verify policy routing configuration when starting up to make sure that
policy
routing tables do not override default routing tables.
* "ctdb scriptstatus" should correctly list the number of scripts executed.
* Do not run eventscripts at real-time priority.
* Make sure "ctdb restoredb" and "ctdb wipedb" cannot affect an ongoing
recovery.
* If a readonly record revokation fails, CTDB does not abort anymore. It
will
retry revoke.
* pending_calls statistic now gets updated correctly.
Important internal changes
--------------------------
* Vacuuming performance has been improved.
* Fix the order of setting recovery mode and freezing databases.
* Remove NAT gateway "monitor" event.
* Add per database queue for lock requests. This improves the lock
scheduling performance.
* When processing dmaster packets (DMASTER_REQUEST and DMASTER_REPLY) defer
all
call processing for that record. This avoids the temporary inconsistency
in
dmaster information which causes rapid bouncing of call request between
two
nodes.
* Correctly capture the output from lock helper processes, so it can be
logged.
* Many test improvements and additions.
