This provides a separate script for handling local daemons. It can be
used for testing outside of the CTDB simple test suite. It is
installed as ctdb_local_daemons.
The logic is copied from ctdb/tests/simple/scripts/local_daemons.bash.

CTDB needs the legacy/00.ctdb event script to be able to function
properly. If this script is not enabled then assume a first-time
install or an upgrade to a version that requires events scripts to be
enabled via symlinks. In these cases enable this script and other
commonly used scripts.
Remove links during uninstall (but not during upgrade).

Using CTDB_SET_TunableVariables in the main configuration file is no

The only subtlety is an unexpected order change in one of the unit

The change to ctdbd.conf and removal of /etc/sysconfig/ctdb as a
configuration file makes RPM rename the latter with a .rpmsave suffix.
This means that a working configuration is moved aside on upgrade and
manual intervention is needed.
Avoid this by convincing RPM that the existing /etc/sysconfig/ctdb is
still a configuration file.

This will allow killing of TCP connections without daemon involvement.
It looks strange that the common code for daemon and helper is in the

temporary changes to the build configuration. This code will move

If the files section uses %{_libexecdir} then CTDB must also be
configured to build and install with the same path, otherwise rpmbuild
can fail due to a mismatch. "rpmbuild --showrc" indicates that the
default %configure command sets:
--libexecdir=%{_libexecdir} \
A mismatch will occur on SUSE systems, where SLES 12 and OpenSUSE 12
set _libexecdir to %{_exec_prefix}/lib.
The failure was initially seen when testing on Debian where
_libexecdir is set to %{_prefix}/lib/x86_64-linux-gnu, though Debian
is an unlikely platform for building RPMs...

This is intended to replace the use of "ctdb natgwlist" in 11.natgw
and provide different views of the NAT gateway status.
It replaces the use of CTDB_NATGW_SLAVE_ONLY=yes with a "slave-only"
keyword in the NAT gateway nodes file. This means the nodes file must
be consistent on all nodes in a NAT gateway group.
Note that this script is not yet integrated, so there are no behaviour
or documentation changes.

Parallel database recovery fixes the samba/ctdb deadlock during recovery.
Many times samba tries to grab multiple record locks in sequence.
Consider a case when samba is already holding a record lock on a database
and tries to get a record lock on second database. If the second record
is not available on the local node, samba asks ctdb to migrate the record.
If recovery occurs at this time (e.g. node becoming inactive), ctdb
cannot freeze all the databases since samba is already holding a lock
and waiting for the second lock. CTDB can process the second record
request only after the recovery is complete, thus causing a deadlock.
In parallel database recovery, each database is frozen and recovered
independent from each other. So as soon as the second database is
recovered, CTDB will resend all the pending migration requests and Samba
can get the second lock. Once samba releases both the locks, ctdb can
freeze the first database and recover it completing recovery process.
