705e4174c9 ctdb-recoverd: Gently abort recovery when election is underway
Sometimes the recovery daemon fails to get the recovery lock on one
node so that node is banned.  This seems to always happen during an
election.  The recovery is triggered because other nodes are found to
have recovery mode enabled.  They have recovery mode enabled because
an election has been forced.

The recovery daemon's main_loop() only does an initial check for an
election.  After that, a node can force an election and, in the
process, set itself to be the current winner.  In this situation,
verify_recmode() will always return MONITOR_RECOVERY_NEEDED so
do_recovery() is called.  If the previous recovery master hasn't
admitted defeat and released the recovery lock, then do_recovery()
will rightly fail.  However, it would be better if it failed a little
more gracefully, since this case is not that unusual.

Instead of trying to take the recovery lock, return early with an
error if there is an election in progress.  Note that the race is
still there but it is now much narrower.

There are probably more subtle ways of avoiding this issue, including
something like this in main_loop():

-	if (pnn != rec->recmaster) {
+	if (pnn != rec->recmaster || rec->election_timeout) {
 		return;
 	}

However, this check is done earlier so it leaves the race window open
a little wider.

55fbe364b9 ctdb-daemon: Support per-node robust mutex feature
To enable TDB mutex support, set tunable TDBMutexEnabled=1.

When databases are attached for the first time, attach flags must include
TDB_MUTEX_LOCKING and TDBMutexEnabled must set to enable mutex support.

However, when CTDB attaches databases internally for recovery, it will
enable mutex support if TDBMutexEnabled is set.

e454e5ac9c ctdb-daemon: Check PID in ctdb_remove_pidfile(), not unreliable flag
If something unexpectedly uses fork() then an exiting child will
remove the PID file while the main daemon is still running.  The real
test is whether the current process has the PID of the main CTDB
daemon, which is the process that calls setsid().

This could be done using getpgrp() instead.  At the moment the
eventscript handler harmlessly calls setpgid() - harmless because the
atexit() handlers are cleared upon exec().  However, it is possible
that process groups will be used more in future so it is probably
better to rely on the session ID.

Thanks to Sumit Bose <sbose@redhat.com> for the idea.

aac607d727 ctdb-eventscripts: Ensure $GANRECDIR points to configured subdirectory
Check that the $GANRECDIR symlink points to the location specified by
$CTDB_GANESHA_REC_SUBDIR and replace it if incorrect.  This handles
reconfiguration and filesystem changes.

While touching this code:

* Create the $GANRECDIR link as a separate step if it doesn't exist.
  This means there is only 1 place where the link is created.

* Change some variables names to the style used for local function
  variables.

* Remove some "ln failed" error messages.  ln failures will be logged
  anyway.

* Add -v to various mkdir/rm/ln commands so that these actions are
  logged when they actually do something.

6a552f1a12 ctdb-tests: Try harder to avoid failures due to repeated recoveries
About a year ago a check was added to _cluster_is_healthy() to make
sure that node 0 isn't in recovery.  This was to avoid unexpected
recoveries causing tests to fail.  However, it was misguided because
each test initially calls cluster_is_healthy() and will now fail if an
unexpected recovery occurs.

Instead, have cluster_is_healthy() warn if the cluster is in recovery.

Also:

* Rename wait_until_healthy() to wait_until_ready() because it waits
  until both healthy and out of recovery.

* Change the post-recovery sleep in restart_ctdb() to 2 seconds and
  add a loop to wait (for 2 seconds at a time) if the cluster is back
  in recovery.  The logic here is that the re-recovery timeout has
  been set to 1 second, so sleeping for just 1 second might race
  against the next recovery.

* Use reverse logic in node_has_status() so that it works for "all".

* Tweak wait_until() so that it can handle timeouts with a
  recheck-interval specified.

4dd382296d ctdb-tools-ctdb: Make natgwlist and lvsmaster more resilient
Recent changes have caused these commands to attempt to get
capabilities from all nodes before doing further filtering.  This
means that capabilities are unnecessarily fetched from nodes that are
unlikely to be the master.  If such a node does not answer the control
then many nodes can fail to calculate the master node.  In the case of
natgwlist this will cause "monitor" events to fail resulting in
unhealthy nodes.

Restore the behaviour where capabilities are only fetched for a node
that will be the master if it has the desired flags.

Although this masks a problem where a connected node is not replying,
it can help to avoid an outage in some cases.

Add supporting tests and infrastructure.  Infrastructure just lets a
timeout be faked - just for ctdb_ctrl_getcapabilities_stub() so far.
First test checks that this infrastructure works if the first node
times out in natgwlist.  Second test checks the case worked around by
the above fix - that is, no failure when a node with PNN beyond the
NATGW master can time out.

a1e1b81b9c ctdb-tools/ctdb: Detach databases only if all nodes disallow client access
This makes sure that AllowClientDBAttach is set to 0 before detaching any
databases.

If someone enables the tunable between checking of tunable and actual
detaching of databases, then they deserve what they get. :-)

2f2421bae1 ctdb-eventscripts: CTDB_NATGW_PUBLIC_* optional on slave-only nodes
Commit 4ee4925d41 forgot about
CTDB_NATGW_SLAVE_ONLY so it introduces an incorrect failure when this
is set, and CTDB_NATGW_PUBLIC_IFACE or CTDB_NATGW_PUBLIC_IP is unset.

Relax the sanity check to see if CTDB_NATGW_SLAVE_ONLY is set.

Update the documentation to explicitly state that
CTDB_NATGW_PUBLIC_IFACE and CTDB_NATGW_PUBLIC_IP are optional and
unused if CTDB_NATGW_SLAVE_ONLY is set.  It would be possible to
insist that CTDB_NATGW_PUBLIC_IFACE and CTDB_NATGW_PUBLIC_IFACE should
be unset in that case.  However, it is more reasonable to allow
consistent configuration across nodes except with some nodes
configured slave-only.

Add tests, update infrastructure and fix a thinko in the stub's
"natgwlist" implementation.

ce8ac88b96 ctdb-tools-ctdb: Drop disconnected nodes when filtering by capability
Commit ba69742ccd missed the point of
filtering disconnected nodes while limiting the nodemap to those in
the NAT gateway group.  It was really to avoid trying to fetch
capabilities from disconnected nodes.  This should be explicitly done
in filter_nodemap_by_capabilities(), otherwise "ctdb natgwlist" simply
fails when there is a disconnected node.

Note that the alternate solution where filter_nodemap_by_flags() is
called before filter_nodemap_by_capabilities() would not be not
correct.  Filtering on flags first can produce a "healthier" set of
nodes where none of them have the NAT gateway capability.

Also extend stub for ctdb_ctrl_getcapabilities() to fail when trying
to get capabilities from a disconnected node and add a corresponding
test to confirm that "ctdb natgwlist" is no longer broken.
